[0002] Currently, when an application is compiled, compilation optimization is performed to improve the startup and running speed of the application. Various optimization modules are called during compilation to optimize the source code, such as dead source code elimination, constant folding, inline optimization, etc. Inline optimization is to insert the source code of the inline function directly into the call point during the compilation process. When the program is running, it does not need to execute the function call step, but directly executes the source code of the inline function, thereby saving the function call overhead.

[0003] However, if the body of an inline function is large and is frequently called from multiple locations, the source code size will increase significantly, which may cause the application's operating efficiency to decrease. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The terms "at least one (item)", "at least one of" and the like in the specification and claims of the present application refer to any one, any two or a combination of more than two of the objects included therein. For example, at least one (item) of a, b, and c can be represented by: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" refers to two or more, and its meaning is similar to that of "at least one (item)".

[0023] The following is an explanation of some concepts and / or terms involved in the compilation method provided in the embodiments of the present application.

[0024] 1. Inline function: It is used to prompt the compiler to embed the function body directly into the calling point when the function is called, instead of through the conventional function calling mechanism.

[0025] 2. Inline functions are declared using the inline keyword. Usually, inline is used at the definition of a function, as shown below:

[0026] inline int add(int a,int b){

[0027] Return a+b;

[0028] }

[0029] In this example, the add function is declared as an inline function. When the add function is called in the source code, the compiler will try to insert the body of this function directly into the call site instead of performing a function call.

[0030] 3. Speed-profile compilation mode. When the application editing mode is speed-profile compilation mode, the application source code is compiled according to at least one frequently called function recorded in the profile file. The application source code is partially compiled.

[0031] 4. Speed ​​compilation mode. When the compilation mode of the application is speed compilation mode, the source code of the application is fully compiled, and there is no need to call functions when compiling the source code.

[0032] The compilation method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] The compilation method in the embodiment of the present application can be applied to the scenario of source code compilation.

[0034] At present, when compiling frameworks and applications, Ahead-of-Time (AOT) compilation optimization and Just-In-Time (JIT) compilation optimization are performed to improve the startup and running speed of frameworks and applications. Various optimization modules are called during compilation to optimize the source code, such as dead source code elimination, constant folding, inline optimization, etc. In order to implement calls between source codes, the compiler needs to allocate an active area for each source code, save the caller for each parameter, create the callee's environment, transfer control to the callee, and finally pass parameters when returning. Inline optimization is to directly convert the called function to the call point, which can be used to reduce the overhead of function calls, facilitate escape analysis and delete repeated memory barrier (LoadStore) operations, and obtain more optimization opportunities to improve the execution efficiency of source code. However, through inlining, the inline optimization module will try to replace all called functions during the source code compilation process. However, if the function body of the called function is large and is frequently called in multiple locations, it will cause a significant increase in the source code volume and cause source code expansion. This may result in a decrease in the operating efficiency of the application.

[0035] In the compilation method, device, electronic device and storage medium provided in the embodiments of the present application, when compiling the first source code of the first application, the electronic device performs function inlining on the first source code and the function body corresponding to the first function to generate the second source code only when it is determined that the calling frequency of the first function in the first source code is greater than or equal to the first threshold, that is, when it is determined that the first function is a frequently called function, thereby reducing the number of times the first application performs function inlining and avoiding a substantial increase in the source code volume of the first application. This improves the operating efficiency of the application.

[0036] The execution subject of the compilation method provided in the embodiment of the present application may be a compilation device, and the compilation device may be an electronic device, or a functional module or entity in an electronic device. The technical solution provided in the embodiment of the present application is described below using an electronic device as an example.

[0037] The present application embodiment provides a compilation method. Figure 1 A flowchart of a compilation method provided by an embodiment of the present application is shown, and the method can be applied to electronic devices. Figure 1 As shown, the compilation method provided in the embodiment of the present application may include the following steps 201 and 202.

[0038] Step 201: When compiling a first source code of a first application, the electronic device obtains a first function identifier.

[0039] In an embodiment of the present application, the above-mentioned first function identifier is used to indicate the first function in the first source code.

[0040] In some embodiments of the present application, the first application may be any one of the following: a communication application, a payment application, a shopping application, a reading application, a video application, etc. The embodiments of the present application do not limit this.

[0041] In some embodiments of the present application, the first source code may be a source code corresponding to any source code segment in the application source code of the first application, and each source code segment corresponds to a function.

[0042] In some embodiments of the present application, the first function may be an inline function.

[0043] In some embodiments of the present application, the first function identifier may be a unique identifier of the first function, that is, the address of the function in the memory.

[0044] It should be noted that the source code in the embodiments of the present application can be understood as code, which is not limited in the embodiments of the present application.

[0045] Step 202: When the first function identifier matches any one of the at least one second function identifier, the electronic device inlines the first source code and the function body corresponding to the first function to generate a second source code.

[0046] In an embodiment of the present application, the second function identifier is used to indicate a function in the first application whose calling frequency is greater than or equal to a first threshold.

[0047] In some embodiments of the present application, the second function identifier may be a unique identifier of the function.

[0048] In some embodiments of the present application, the calling frequency of a function is greater than or equal to a first threshold, which can be understood as the function is often called.

[0049] In some embodiments of the present application, the electronic device may first determine whether the first function identifier matches any one of at least one second function identifier, and then, when the first function identifier matches any one of at least one second function identifier, the electronic device may inline the first source code and the function body corresponding to the first function to generate a second source code.

[0050] In some embodiments of the present application, the electronic device determines whether a first function identifier matches any one of at least one second function identifier, which can be understood as: the electronic device determines whether the calling frequency of the first function indicated by the first function identifier is greater than or equal to a first threshold, that is, determines whether the first function is frequently called.

[0051] In some embodiments of the present application, the electronic device may compare the first function identifier with at least one second function identifier to determine whether the first function identifier matches any one of the at least one second function identifier.

[0052] It can be understood that since the second function identifier is used to indicate a function in the first application whose calling frequency is greater than or equal to the first threshold, when the first function identifier matches any one of at least one second function identifier, the calling frequency of the first function indicated by the first function identifier is also greater than or equal to the first threshold, and therefore it can be determined that the first function is frequently called.

[0053] In some embodiments of the present application, Figure 1 ,like Figure 2 As shown, before the above step 201, the compilation method provided in the embodiment of the present application also includes the following step 301.

[0054] Step 301: The electronic device obtains a configuration file of a first application.

[0055] In an embodiment of the present application, the above configuration file includes at least one second function identifier.

[0056] In some embodiments of the present application, the above configuration file may be a profile file.

[0057] In some embodiments of the present application, the electronic device determining whether the first function identifier matches any one of the at least one second function identifier can also be understood as: the electronic device determining whether the first function identifier exists in the configuration file.

[0058] In some embodiments of the present application, the electronic device may record in the configuration file the functions in the first application whose calling frequency is greater than or equal to the first threshold.

[0059] In some embodiments of the present application, the function whose calling frequency indicated by the second function identifier is greater than or equal to the first threshold may be at least one of the following: a function called when the first application is started, and a function called when the first application is run.

[0060] In some embodiments of the present application, when the first application is started, the electronic device can record the function called when the first application is started, and then record the function identifier in a configuration file when the number of function calls is greater than or equal to a first threshold.

[0061] In some embodiments of the present application, when running a first application, the electronic device may record a function called when running the first application, and then record a function identifier in a configuration file when the number of function calls is greater than or equal to a first threshold.

[0062] In this way, since the electronic device can record the functions in the first application whose calling frequency is greater than or equal to the first threshold in the configuration file, it can determine whether the calling frequency of the first function is greater than or equal to the first threshold by comparing the first function identifier with at least one second function identifier in the configuration file, that is, determine whether the first function is a commonly used function, and then perform inline optimization if the first function is a commonly used function, thereby reducing the number of times the first application performs function inlining, avoiding a substantial increase in the source code volume of the first application, and thus improving the operating efficiency of the application.

[0063] In some embodiments of the present application, the electronic device may call TryInlineAndReplace to perform function inlining on the first source code and the function body corresponding to the first function to generate a second source code.

[0064] In some embodiments of the present application, the electronic device can find the function body of the first function through the first function identifier, so as to inline the first source code and the function body corresponding to the first function to generate the second source code.

[0065] In some embodiments of the present application, the electronic device performs function inlining on the first source code and the function body corresponding to the first function, which can be understood as the electronic device replacing the function body of the first function with the calling source code.

[0066] In some embodiments of the present application, when the first function identifier does not match at least one second function identifier, the electronic device does not perform function inlining.

[0067] It can be understood that since the second function identifier is used to indicate a function in the first application whose calling frequency is greater than or equal to the first threshold, when the first function identifier does not match at least one second function identifier, the calling frequency of the first function indicated by the first function identifier is lower, that is, the first function is not called frequently, and therefore the electronic device may not perform function inlining.

[0068] In some embodiments of the present application, Figure 3 As shown, it is a flowchart of an electronic device performing inline optimization on a first source code of a first application, including the following steps S1 to S5.

[0069] S1. When compiling a first source code of a first application, the electronic device obtains a unique identifier of a first function.

[0070] S2. Obtain a configuration file of the first application, and obtain a unique identifier of at least one function whose calling frequency is greater than or equal to a first threshold.

[0071] S3. The electronic device determines whether the unique identifier of the first function matches any one of the at least one unique identifier included in the configuration file.

[0072] If the unique identifier of the first function matches any one of the at least one unique identifier included in the configuration file, the electronic device executes step S4; if the unique identifier of the first function does not match any one of the at least one unique identifier included in the configuration file, the electronic device executes step S5;

[0073] S4. The electronic device inlines the first source code and the function body corresponding to the first function to generate a second source code.

[0074] S5. The electronic device determines that the inline optimization of the first function is completed.

[0075] It should be noted that for the relevant description of step S1 to step S5, reference can be made to the contents of the above embodiment, which will not be repeated here.

[0076] In some embodiments of the present application, the electronic device compiles the first source code of the first application including the following five examples:

[0077] Example 1: When the electronic device compiles the first source code of the first application, it first determines whether the first function is a static function or a directly called function (IsInvokeStaticOrDirect). When the first function is a static function or a directly called function, the electronic device can determine whether the calling frequency of the first function is greater than or equal to a first threshold. Then, when the calling frequency of the first function is greater than or equal to the first threshold, the electronic device can inline the first source code and the function body corresponding to the first function to generate a second source code.

[0078] In some embodiments of the present application, when the first function is a static function or a directly called function, the electronic device can directly obtain the first function identifier through the GetResolved method to determine whether the calling frequency of the first function is greater than or equal to the first threshold.

[0079] In this way, after determining that the first function is a static function or a directly called function, the electronic device adds a judgment on the heat value (i.e., the calling frequency) of the first function. If the heat value of the first function is not high, the function inlining operation is not performed. If the heat value of the first function is high, the function inlining operation is performed on it. Therefore, compared with the related art, the method of directly performing the function inlining operation on the first function after determining that the first function is a static function or a directly called function reduces the number of times the first application performs function inlining, avoids a substantial increase in the source code volume of the first application, and thus improves the operating efficiency of the application.

[0080] Example 2: When the first function is not a static function or a directly called function, the electronic device can determine whether the first function is a virtualized call, and then when the first function is a virtualized call, the electronic device can determine whether the calling frequency of the first function is greater than or equal to a first threshold, and then when the calling frequency of the first function is greater than or equal to the first threshold, the electronic device can inline the first source code and the function body corresponding to the first function to generate a second source code.

[0081] In some embodiments of the present application, when the first function is a virtualized call, the electronic device may obtain the first function identifier through Class Hierarchy Analysis (CHA) to determine whether the calling frequency of the first function is greater than or equal to a first threshold.

[0082] In some embodiments of the present application, the electronic device may call the function TryInlineFromCHA to obtain the first function identifier.

[0083] In some embodiments of the present application, the electronic device may call TryInlineAndReplace to inline the first source code and the function body corresponding to the first function.

[0084] In some embodiments of the present application, the electronic device may use AddCHAGuard to perform deoptimization judgment and processing.

[0085] In this way, after determining that the first function is a virtualization call, the electronic device adds a judgment on the heat value of the first function. If the heat value of the first function is not high, the function inline operation is not performed. If the heat value of the first function is high, the function inline operation is performed on it. Therefore, compared with the related technology, the method of directly performing a function inline operation on the first function after determining that the first function is a virtualization call reduces the number of times the first application performs function inlining, avoids a substantial increase in the source code volume of the first application, and thus improves the operating efficiency of the application.

[0086] Example three, when the first function is not a static function or a directly called function, and the first function is not a virtualized call, the electronic device can determine whether the first function exists in an inline cache area (InlineCache). When the first function exists in the inline cache area, the electronic device can determine whether the calling frequency of the first function is greater than or equal to a first threshold. Then, when the calling frequency of the first function is greater than or equal to the first threshold, the electronic device can inline the first source code and the function body corresponding to the first function to generate a second source code.

[0087] In some embodiments of the present application, when the first function exists in the inline cache area, the electronic device can determine whether the first function is monomorphic or polymorphic. When the first function is monomorphic, TryInlineMonomorphicCall is called to obtain the first function identifier; when the first function is polymorphic, TryInlinePolymorphicCallToSameTarget is called to obtain the first function identifier to determine whether the calling frequency of the first function is greater than or equal to the first threshold.

[0088] In some embodiments of the present application, the electronic device may call the function TryInlineFromInlineCache to obtain the first function identifier.

[0089] In some embodiments of the present application, when the first function is monomorphic (TryInlineMonomorphicCall), the electronic device can obtain class_index through FindClassIndexIn, and then obtain monomorphic_type through GetMonomorphicType(classes), and then obtain the function identifier of the actual called function through the Resolve method FromInlineCache(monomorphic_type, invoke_instruction, pointer_size).

[0090] In some embodiments of the present application, when the first function is polymorphic (TryInlinePolymorphicCall), the processing is divided into two cases. First, TryInlinePolymorphicCallToSameTarget is called to handle the situation of multiple invokes of the same method. Here, the actual real function and the function identifier of the real function being called are found by traversing various types, and then a judgment is made. The remaining processing of multiple invokes of different methods is also to traverse various corresponding types to find the actual real function and the function identifier of the real function being called.

[0091] In this way, after determining that the first function exists in the inline cache area, the electronic device adds a judgment on the heat value of the first function. If the heat value of the first function is not high, the function inline operation is not performed. If the heat value of the first function is high, the function inline operation is performed on it. Therefore, compared with the related art, the method of directly performing function inline operation on the first function after determining that the first function exists in the inline cache area reduces the number of times the first application performs function inlining, avoids a substantial increase in the source code volume of the first application, and thus improves the operating efficiency of the application.

[0092] In some embodiments of the present application, Figure 4 As shown, it is a flowchart of an electronic device performing inline optimization on a first source code of a first application, including the following steps S11 to S19:

[0093] S11. The electronic device determines whether the first function is a static function or a directly called function.

[0094] When the first function is a static function or a directly called function, execute steps S12 and S13; when the first function is not a static function or a directly called function, execute step S14;

[0095] S12: The electronic device directly obtains a first function identifier.

[0096] S13: The electronic device determines a calling frequency of the first function, and when the calling frequency of the first function is greater than or equal to a first threshold, the electronic device performs inline optimization.

[0097] S14: The electronic device determines whether the first function is a virtualization call.

[0098] When the first function is a virtualized call, execute steps S15 and S13; when the first function is not a virtualized call, execute step S16;

[0099] S15. The electronic device obtains a first function identifier through CHA.

[0100] S16. The electronic device determines whether the first function exists in the inline cache area.

[0101] When the first function exists in the InlineCache, step S17 is executed; when the first function does not exist in the InlineCache, the process ends;

[0102] S17. The electronic device determines whether the first function is monomorphic or polymorphic.

[0103] When the first function is monomorphic, steps S18 and S13 are executed; when the first function is polymorphic, steps S19 and S13 are executed;

[0104] S18. The electronic device calls TryInlineMonomorphicCall to obtain a first function identifier.

[0105] S19. The electronic device calls TryInlinePolymorphicCallToSameTarget to obtain a first function identifier.

[0106] It should be noted that for the relevant description of step S11 to step S19, reference can be made to the contents of the above embodiment, which will not be repeated here.

[0107] Example 4, in combination with Example 1, when the first function is a static function or a directly called function, and the calling frequency of the first function is greater than or equal to a first threshold, when the electronic device inlines the first source code and the function body corresponding to the first function, if the function inlining fails, the electronic device can determine whether the first function is a virtualization call. When the first function is a virtualization call, the electronic device can obtain the first function identifier through CHA, and then re-determine whether the calling frequency of the first function is greater than or equal to the first threshold. Then, when the calling frequency of the first function is greater than or equal to the first threshold, the first source code and the function body corresponding to the first function are inlined to generate a second source code.

[0108] It can be understood that the failure of the electronic device to execute function inlining indicates that it is wrong to directly obtain the first function identifier through the GetResolved method. Therefore, the electronic device can determine whether the first function is a virtualization call. When the first function is a virtualization call, the electronic device can obtain the first function identifier again through CHA to determine whether the calling frequency of the first function is greater than or equal to the first threshold. Then, when the calling frequency of the first function is greater than or equal to the first threshold, the first source code and the function body corresponding to the first function are inlined to generate a second source code.

[0109] Example 5, in combination with Example 4, when the first function is a static function or a directly called function, and the calling frequency of the first function is greater than or equal to the first threshold, the electronic device inlines the first source code and the function body corresponding to the first function, but the function inlining fails. Then, when the first function is a virtualized call and it is determined that the calling frequency of the first function is greater than or equal to the first threshold, the electronic device inlines the first source code and the function body corresponding to the first function, but the function inlining fails again, the electronic device can determine whether the first function exists in the inline cache area. When the first function exists in the inline cache area, the electronic device can determine whether the first function is monomorphic or polymorphic. When the first function is monomorphic, TryInlineMonomorphicCall is called to obtain the first function identifier again; when the first function is polymorphic, TryInlinePolymorphicCallToSameTarget is called to obtain the first function identifier again to determine whether the calling frequency of the first function is greater than or equal to the first threshold. Then, when the calling frequency of the first function is greater than or equal to the first threshold, the first source code and the function body corresponding to the first function are inlined to generate a second source code.

[0110] It can be understood that the failure of the electronic device to execute function inlining indicates that the first function identifier obtained through CHA is incorrect. Therefore, the electronic device can determine whether the first function exists in the inline cache area. When the first function exists in the inline cache area, the electronic device can re-obtain the first function identifier to re-determine whether the calling frequency of the first function is greater than or equal to the first threshold. Then, when the calling frequency of the first function is greater than or equal to the first threshold, the first source code and the function body corresponding to the first function are inlined to generate a second source code.

[0111] In this way, after the function inlining fails, the electronic device can re-obtain the first function identifier through other means and re-judge the heat value of the first function. If the heat value of the first function is not high, the function inlining operation is not performed. If the heat value of the first function is high, the function inlining operation is performed on it. Therefore, compared with the related technology, after the function inlining fails, the method of directly performing the function inlining operation on the first function after obtaining the first function identifier through other means reduces the number of times the first application performs function inlining, avoids a substantial increase in the source code volume of the first application, and thus improves the operating efficiency of the application.

[0112] In some embodiments of the present application, before the above-mentioned step 201, the electronic device may determine the compilation mode of the first application. When it is determined that the compilation mode of the first application is the speed-profile compilation mode, the electronic device starts to execute step 201, that is, starts to execute the inline optimization solution of the present application.

[0113] In some embodiments of the present application, the compilation mode of the first application may also be the compilation mode of the framework corresponding to the first application, which is not limited in the embodiments of the present application.

[0114] In some embodiments of the present application, when it is determined that the compilation mode of the first application is the speed compilation mode, the electronic device does not need to execute the inline optimization solution of the present application.

[0115] It can be understood that when the compilation mode of the first application is the speed compilation mode, the source code of the first application is fully compiled and does not need to call functions, so there is no need to execute the inline optimization solution of the present application.

[0116] In some embodiments of the present application, before determining the compilation mode of the first application, the electronic device may first set a mutex to synchronize access to certain data structures, and then determine the compilation mode of the first application.

[0117] In some embodiments of the present application, before the above step 201, the compiling method provided by the embodiment of the present application further includes the following step 401. In addition, the "electronic device inlines the first source code and the function body corresponding to the first function" in the above step 202 can be specifically implemented by the following step 202a.

[0118] Step 401: The electronic device determines a first value.

[0119] In an embodiment of the present application, the above-mentioned first value is the maximum number of function inline instructions corresponding to the first application.

[0120] In some embodiments of the present application, the above-mentioned maximum number of function inline instructions can also be understood as: the maximum number of function inline times, that is, the maximum number of times the electronic device can execute function inlining when compiling the source code of the first application.

[0121] In some embodiments of the present application, the above step 401 can be specifically implemented through the following step 401a.

[0122] Step 401a: The electronic device determines a first value according to the first information.

[0123] In an embodiment of the present application, the first information includes information for indicating at least one of the following: a computing capability of the electronic device, a usage frequency of the first application, and a number of at least one second function identifier.

[0124] In some embodiments of the present application, the electronic device may determine the computing capability of the electronic device based on the processor type of the electronic device.

[0125] In some embodiments of the present application, the processor type of the electronic device includes any of the following: high-end type, mid-end type, and low-end type.

[0126] It can be understood that the higher the level of the processor type of an electronic device, the stronger the computing power of the electronic device.

[0127] In some embodiments of the present application, the first information is used to indicate the computing capability of the electronic device and the usage frequency of the first application; the step 401a can be specifically implemented through the following step 401a1.

[0128] Step 401a1: The electronic device determines a first value according to the computing capability of the electronic device and the usage frequency of the first application.

[0129] In an embodiment of the present application, the computing capability of the electronic device and the usage frequency of the first application are positively correlated with the first value.

[0130] It can be understood that the stronger the computing power of the electronic device is, the larger the first value is; and the higher the frequency of use of the first application is, the larger the first value is.

[0131] In some embodiments of the present application, the electronic device may determine a first range corresponding to the computing power of the electronic device, and then when the usage frequency of the first application is greater than or equal to a second threshold, add the second value to the first adjustment value to obtain the above-mentioned first value.

[0132] Exemplarily, the computing capabilities of the electronic device are different, and the corresponding first ranges are also different. The stronger the computing capability of the electronic device is, the larger the upper limit value of the corresponding first range is.

[0133] Exemplarily, when the usage frequency of the first application is greater than or equal to the second threshold, the first application is a frequently used application.

[0134] Exemplarily, the second numerical value may be a median value of the first range.

[0135] Exemplarily, the first adjustment value may be a first preset value, and the first adjustment value is an adjustment value corresponding to the usage frequency of the first application.

[0136] For example: assuming that the first range corresponding to the computing power of the electronic device is (512, 1024), the median value of the first range is 768 (that is, the second value mentioned above), and the first adjustment value is 100; when the usage frequency of the first application is greater than the second threshold, the electronic device can determine that the first value is: 768+100=868.

[0137] In some embodiments of the present application, when the usage frequency of the first application is less than the second threshold, the electronic device may subtract the second value from the first adjustment value to obtain the above-mentioned first value.

[0138] In some embodiments of the present application, the first value is within a first range.

[0139] In some embodiments of the present application, when the value obtained after adding the first adjustment value to the second value exceeds the upper limit of the first range, the electronic device may use the upper limit of the first range as the first value.

[0140] In some embodiments of the present application, when the value obtained after subtracting the second value from the first adjustment value does not exceed the lower limit of the first range, the electronic device may use the lower limit of the first range as the first value.

[0141] In some embodiments of the present application, the first information is used to indicate the number of at least one second function identifier; the step 401a can be specifically implemented by the following step 401a2.

[0142] Step 401a2: The electronic device determines a first value according to the number of at least one second function identifier.

[0143] In an embodiment of the present application, the number of the at least one second function identifier is positively correlated with the first numerical value.

[0144] It can be understood that the greater the number of the at least one second function identifier, the greater the first value.

[0145] In some embodiments of the present application, after obtaining the number of the second function identifier, the electronic device can search the storage table, and then use the numerical value corresponding to the number stored in the storage table as the above-mentioned first numerical value.

[0146] In some embodiments of the present application, the electronic device may pre-set a corresponding relationship between the number of second function identifiers and the first numerical value, and store the corresponding relationship in a storage table.

[0147] In some embodiments of the present application, the first information is used to indicate: the computing capability of the electronic device, the usage frequency of the first application, and the number of at least one second function identifier. The step 401a can be specifically implemented by the following step 401a3.

[0148] Step 401a3: The electronic device determines a first value according to the computing capability of the electronic device, the usage frequency of the first application, and the number of at least one second function identifier.

[0149] In some embodiments of the present application, the electronic device may determine a first range corresponding to the computing power of the electronic device, and then when the usage frequency of the first application is greater than or equal to a second threshold, add the second value to the first adjustment value to obtain a third value, and then when the number of at least one second function identifier is greater than or equal to the third threshold, add the third value to the second adjustment value to obtain the above-mentioned first value.

[0150] In some embodiments of the present application, the second adjustment value may be a second preset value, and the second adjustment value is an adjustment value corresponding to the number of the second function identifier.

[0151] Exemplarily, the first preset value and the second preset value may be the same or different.

[0152] For example: assuming that the first range corresponding to the computing power of the electronic device is (512, 1024), the median value of the first range is 768 (i.e., the second value mentioned above), the first adjustment value is 100, and the second adjustment value is 50; when the usage frequency of the first application is greater than the second threshold, the electronic device can determine that the third value is: 768+100=868, and then when the number of at least one second function identifier is greater than the third threshold, the electronic device can determine that the first value is 868+50=918.

[0153] In some embodiments of the present application, when the usage frequency of the first application is less than a second threshold, the electronic device may subtract the second value from the first adjustment value to obtain a fourth value, and then when the number of at least one second function identifier is less than a third threshold, the electronic device may subtract the fourth value from the second adjustment value to obtain the above-mentioned first value.

[0154] In some embodiments of the present application, when the usage frequency of the first application is greater than or equal to a second threshold, the electronic device may add the second value to the first adjustment value to obtain a third value, and then when the number of at least one second function identifier is less than the third threshold, the electronic device may subtract the third value from the second adjustment value to obtain the above-mentioned first value.

[0155] In some embodiments of the present application, when the usage frequency of the first application is less than a second threshold, the electronic device may subtract the second value from the first adjustment value to obtain a fourth value, and then when the number of at least one second function identifier is greater than a third threshold, the electronic device may add the fourth value to the second adjustment value to obtain the above-mentioned first value.

[0156] In some embodiments of the present application, the first value is within a first range.

[0157] In some embodiments of the present application, when a first value calculated by an electronic device exceeds an upper limit value of a first range, the electronic device may use the upper limit value of the first range as the first value.

[0158] In some embodiments of the present application, when the first numerical value calculated by the electronic device does not exceed the lower limit of the first range, the electronic device may use the lower limit of the first range as the first numerical value.

[0159] It should be noted that in the embodiment of the present application, after determining the first range, it is only illustrated by first determining whether the usage frequency of the first application is greater than or equal to the second threshold, and then determining whether the number of at least one second function identifier is greater than or equal to the third threshold. After determining the first range, the electronic device may also first determine whether the number of at least one second function identifier is greater than or equal to the third threshold, and then determine whether the usage frequency of the first application is greater than or equal to the second threshold. The embodiment of the present application is not limited to this.

[0160] In some embodiments of the present application, Figure 5 As shown, it is a flowchart for an electronic device to determine the maximum number of function inline instructions corresponding to a first application, including the following steps S21 to S29.

[0161] S21. The electronic device determines a processor type of the electronic device.

[0162] S22. The electronic device determines a first range corresponding to the processor type.

[0163] S23, the electronic device determines whether the first application is a commonly used application;

[0164] When the electronic device determines that the first application is a commonly used application, steps S24 and S26 are executed; when the electronic device determines that the first application is not a commonly used application, steps S25 and S26 are executed;

[0165] S24, the electronic device increases the number of function inline instructions corresponding to the first application;

[0166] S25, the electronic device reduces the number of inline function instructions corresponding to the first application;

[0167] S26. The electronic device determines whether the number of at least one second function identifier is greater than a third threshold;

[0168] When the number of at least one second function identifier is greater than the third threshold, executing step S27, and when the number of at least one second function identifier is less than the third threshold, executing step S28;

[0169] S27, the electronic device increases the number of inline function instructions corresponding to the first application;

[0170] S28, the electronic device reduces the number of inline function instructions corresponding to the first application;

[0171] S29. The electronic device obtains a maximum number of function inline instructions corresponding to the first application.

[0172] It should be noted that for the relevant description of steps S21 to S29, reference can be made to the contents of the above embodiments, which will not be repeated here.

[0173] Step 202a: When the first instruction number is less than the first value, the electronic device inlines the first source code and the function body corresponding to the first function.

[0174] In an embodiment of the present application, the first number of instructions is: the number of instructions for inlining the source code of the first application and the function body corresponding to the function.

[0175] It can be understood that when the electronic device compiles the first source code of the first application, it can first determine whether the number of instructions for inlining the source code of the first application and the function body corresponding to the function exceeds the maximum number of function inlining instructions corresponding to the first application. If it does not exceed, the first source code and the function body corresponding to the first function are inlined; if it exceeds, the inline optimization is not performed.

[0176] In this way, since the electronic device can determine the maximum number of function inline instructions suitable for the application based on information such as the processor type, whether it is a commonly used application, and the number of functions with higher calling frequency in the configuration file, compared with the related art, the maximum number of function inline instructions corresponding to all applications is the same. When applications with larger volumes (for example, configuration files exceeding 200KB and application volumes exceeding 200MB) are compiled using the same maximum number of function inline instructions, the source code volume will increase significantly. The present application can determine the maximum number of function inline instructions suitable for the application, thereby avoiding a significant increase in the source code volume. At the same time, as the source code volume is reduced, the memory used when the application is running will also be reduced, thereby improving the running smoothness, reducing the application compilation power consumption, and improving the battery life.

[0177] The compilation method provided in the embodiment of the present application, when compiling the first source code of the first application, the electronic device performs function inlining on the first source code and the function body corresponding to the first function to generate the second source code only when it determines that the calling frequency of the first function in the first source code is greater than or equal to the first threshold, that is, when it determines that the first function is a frequently called function, thereby reducing the number of times the first application performs function inlining and avoiding a substantial increase in the source code volume of the first application. Thus, the running efficiency of the application is improved.

[0178] It should be noted that the compilation method provided in the embodiment of the present application can be executed by a compilation device. In the embodiment of the present application, the compilation device provided in the embodiment of the present application is described by taking the compilation method executed by the compilation device as an example.

[0179] It should be noted that the above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or, under the premise that there is no contradiction, can also be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of the present application do not limit this.

[0181] The acquisition module 71 is used to acquire a first function identifier when compiling a first source code of a first application, where the first function identifier is used to indicate a first function in the first source code.

[0182] The processing module 72 is used to inline the first source code and the function body corresponding to the first function to generate a second source code when the first function identifier obtained by the acquisition module 71 matches any one of at least one second function identifier; wherein the second function identifier is used to indicate a function in the first application whose calling frequency is greater than or equal to the first threshold.

[0183] The embodiment of the present application provides a compiling device, because when compiling the first source code of the first application, the electronic device performs function inlining on the first source code and the function body corresponding to the first function to generate the second source code only when it determines that the calling frequency of the first function in the first source code is greater than or equal to the first threshold, that is, when it determines that the first function is a frequently called function, thereby reducing the number of times the first application performs function inlining and avoiding a substantial increase in the source code volume of the first application. Thus, the running efficiency of the application is improved.

[0184] In one possible implementation, the acquisition module 71 is also used to inline the first source code and the function body corresponding to the first function when the first function identifier matches any one of at least one second function identifier in the processing module 72, and obtain a configuration file of the first application before generating the second source code, the configuration file including at least one second function identifier.

[0185] In a possible implementation, the compilation device 70 provided in the embodiment of the present application further includes: a determination module; the determination module is used to determine a first value before the acquisition module 71 acquires the first function identifier, the first value being the maximum number of function inline instructions corresponding to the first application. The processing module 72 is specifically used to inline the first source code and the function body corresponding to the first function when the first instruction number is less than the first value determined by the determination module 72; wherein the first instruction number is: the number of instructions for inlining the source code of the first application and the function body corresponding to the function.

[0186] In a possible implementation, the determination module is specifically used to determine a first value based on first information; wherein the first information includes information for indicating at least one of the following: computing power of the electronic device, frequency of use of the first application, and the number of at least one second function identifier.
