Preprocessing method and device of to-be-compiled codes

Abstract

The embodiment of the invention provides a preprocessing method and device of to-be-compiled codes. The method comprises the steps that in the to-be-compiled codes, whether an instruction for rendering a target object is included in the codes for drawing the target object or not is determined; making response to the instruction for rendering the target object, branch structure statements meeting the preset condition in the instruction are replaced with sequential structure statements; the branch structure statements are used for selecting whether rendering is carried out or not, and the sequential structure statements are used for rendering. The branch structure statements meeting the preset condition in the instruction are replaced with the sequential structure statements, the number of Shader variants generated in the compiling process is reduced, therefore, the size of a data package generated after compiling is reduced, and terminal internal storage occupied during operating is reduced. In addition, the embodiment of the invention provides a preprocessing device of the to-be-compiled codes.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of compiling preprocessing, and more specifically, embodiments of the present invention relate to a method and device for preprocessing code to be compiled. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the Unity game development engine, a shader (Shader) refers to a set of instructions used by computer graphics resources when performing rendering tasks, and is mainly used to calculate the color or shade of an image. [0004] When writing the code of the Shader instruction, you can use the #pragma multi_compile statement to macro-define the keyword, that is, you can use the #pragma multi_compile statement to identify the symbol immediately following it as a keyword (Keyword), a...

[0011] In the prior art, the Shader variants that are not used are generally deleted by deleting the Keyword. Specifically, Unity supports the use of the #pragma shader_feature statement in the Shader to delete keywords, but this statement is in conjunction with # When the pragma multi_compile statement is used together, only the switch state with invalid keywords can be deleted, that is, the unused switch state of a keyword can be deleted, but the unused Shader variant cannot be completely deleted, resulting in a large number of keywords In the case of , the compiled data packet is still very large, and the runtime occupies a large memory of the terminal
