Compiler Generates Managed Interface from Unmanaged Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of integrating legacy unmanaged code into a managed runtime environment requires significant development efforts, including hand coding interoperability and creating additional managed code programs, which increases development time and expense.
Innovation Solution
A compiler that compiles unmanaged source code into native object code and generates a managed interface, creating a single assembly that includes both embedded native code and managed interface, eliminating the need for interoperability code and simplifying the integration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unmanaged code is integrated into managed environment using traditional interoperability methods, then native code functionality is available in managed environment, but development complexity and time increase significantly
Solution Approach 1:
The compiler automatically generates managed interface code and metadata from unmanaged source code without requiring manual intervention. The system serves itself by extracting function signatures, parameter types, and return types directly from the unmanaged code and producing the corresponding managed interface definitions and interoperability wrappers automatically.
Solution Approach 2:
The compiler performs preliminary analysis of unmanaged source code during the compilation phase to extract interface information and generate managed code stubs before runtime. This preliminary generation of metadata and interface definitions eliminates the need for developers to manually create interoperability code later.
2Reliability
If manual interoperability code is hand-coded to integrate native libraries, then functionality is achieved, but development time and expense increase
Solution Approach 1:
The compilation system automatically extracts function prototypes, parameter declarations, and return types from unmanaged source code and generates corresponding managed interface definitions. This self-service approach eliminates manual code writing while ensuring accuracy of the generated interfaces.
Solution Approach 2:
The system creates copies of function signatures and interface definitions from the unmanaged code structure, transforming them into managed code equivalents. The metadata and interface stubs are copied and adapted from the original unmanaged declarations, preserving functionality while changing the code representation.
3Adaptability or versatility
If additional managed code programs are created to describe native library prototypes, then interoperability is enabled, but the number of files and compilation steps increase
Solution Approach 1:
The system merges the unmanaged source code compilation with managed interface generation into a single compilation process. Instead of separately compiling unmanaged code, creating managed interface files, and then linking them, the process combines these steps so that managed interface code is generated directly during unmanaged code compilation.
Solution Approach 2:
The compiler performs multiple functions simultaneously: it compiles unmanaged source code to object code, extracts interface information, generates managed interface definitions, and creates metadata - all in a single pass. This multi-functional approach eliminates the need for separate managed code programs and multiple compilation steps.

AI summary
In one embodiment, the present invention includes a method for generating an assembly that is usable in a managed environment. More specifically, the assembly may be an all-inclusive object file that contains a native code module, a managed wrapper and prototype information in a single assembly. The method may include forming an object file from a native code module, where the object file includes prototype information, generating a managed code wrapper using the prototype information, and creating a single assembly including the managed code wrapper and the native code module. In some embodiments, the managed code wrapper may be automatically created, reducing burden on a developer. Other embodiments are described and claimed.
