Coloring language machine code generation method and device of abstract target code architecture

Abstract

The invention discloses a coloring language machine code generation method and device of an abstract target code architecture. The method comprises the steps of defining a set of universal shader abstract target instruction according to a specific type of a GPU shader; converting the intermediate representation code of the coloring language program into an abstract target instruction; designing aninstruction mapping table according to a mapping relationship between the abstract target instruction and an actual GPU target machine instruction; and performing mode matching on the abstract targetinstruction and the instruction mapping table, and converting the abstract target instruction into a target machine instruction executable by a GPU shader. The abstract target code introduced by themethod can decouple the generation part of the compiler rear-end target code from the specific GPU shader machine code, the modularization level of a coloring language compiler rear-end program can begreatly improved, and the difficulty of compiler rear-end development is reduced.

Description

technical field [0001] The invention belongs to the technical field of coloring language compilers, and in particular relates to a method for generating machine codes of an abstract object code framework at the back end of the coloring language compiler. Background technique [0002] A shading language compiler usually consists of three parts: compiler front-end, machine-independent code optimizer, and compiler backend. The general shading language compiler process is as follows: figure 1 shown. The backend part of the compiler mainly includes functions such as generation of target machine code, allocation and management of shader hardware resources, and optimization of machine-related code. Among them, target machine code generation is a key technology in the back-end design of the shader language compiler, and it is also a difficult point in the back-end design of the compiler. The process of this function is complicated and the amount of code is large. [0003] The back...
