Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] figure 1 Be the cross-compiler structure diagram of multi-platform multi-target language based on HLSL according to the present invention, as figure 1 As shown, the cross-compiler 100 of the HLSL-based multi-platform multi-target language of the present invention includes: a code processor 110, a lexical analyzer 120, a syntax analyzer 130 and a code generator 140, wherein,

[0038] The code processor 110 is configured to preprocess the input HLSL code. Among them, the content of preprocessing includes: expanding referenced files, expanding predefined macros, removing comments in codes, and removing useless codes controlled by macros.

Abstract

The invention discloses an HLSL-based multi-platform multi-language cross compiler and a compilation method. The compiler comprises a code processor, a lexical analyzer, a syntactic analyzer and a code generator, wherein the code processor is used for preprocessing an HLSL code; the lexical analyzer is used for carrying out lexical analysis on the preprocessed HLSL code so as to generate a mark; the syntactic analyzer is used for carrying out syntactic analysis on the generated mark so as to construct an abstract syntax tree; and the code generator is used for generating an intermediate code unrelated to platforms according to the abstract syntax tree and generating the intermediate code into a target language code. According to the HLSL-based multi-platform multi-language cross compiler and the compilation method, multi-platform multi-language cross compilation can be realized.

Description

technical field [0001] The invention relates to the technical field of shader language, in particular to an HLSL-based multi-platform multi-target language cross compiler and compiling method. Background technique [0002] The shader language is a development language for programmable GPU pipelines. The code written in the shader language will be compiled by the shader compiler into executable instructions for the GPU. Currently common shader languages ​​include HLSL for Direct3D, GLSL for OpenGL, and MSL for Metal. These shader languages ​​are not syntactically compatible with each other and have their own compilers for their respective platforms. [0003] With the development of technology, especially the rise of mobile platforms, large game engines need to support multiple platforms and multiple graphics interfaces. In order to save development and maintenance costs, a common shader language for multiple platforms has become a common requirement. [0004] There are curre...
