Description
Technical field
Embodiments of the present invention are related to compiler pretreatment technical field, more specifically, embodiments of the present invention are related to
A kind of preprocess method of code to be compiled and device.
Background technology
This part is it is intended that the embodiments of the present invention stated in claims provide background or context.Herein
Description is not because include just recognizing to be prior art in this part.
In Unity development of games engine, tinter (Shader) refers to that one group supplies computer graphical resource in execution wash with watercolours
The instruction using during dye task, is mainly used in calculating color or the light and shade of image.
When writing the code of Shader instruction, it is possible to use #pragma multi_compile sentence enters to keyword
Row macrodefinition, namely symbol followed by can be a keyword using #pragma multi_compile sentence mark
(Keyword), keyword is the mark for labelling branch in shader instruction, and keyword is divided into state of activation and un-activation
Whether state two states, when being compiled to Shader instruction, activate this pass of determination according to keyword in Shader instruction
Whether the code representated by key word can be compiled to code segment, specifically, the keyword being active is compiled into generation
In code section, the keyword being compiled in code segment can be divided into two kinds of on off states of opening and closing again, specifically executes in code
When select to determine whether this keyword executes according to the on off state of keyword.
When writing the code of Shader instruction, use cooperatively with keyword is branch's anticipation code, refers in Shader
Some branches anticipation code can be specified in order, comprise keyword in branch's anticipation code, branch's anticipation code can be according to pass
The on off state of key word selects different branches.
When writing the code of Shader instruction, if being carried out to keyword using #pragma multi_compile sentence
Macrodefinition, and using anticipation branch code in Shader instruction, then when being compiled to Shader instruction, can be to branch
The different branches of anticipation code are combined, and generate different Shader variants, namely anticipation code difference branch of multiple branches
Each group of permutation and combination all correspond to a Shader variant, such that it is able to using different Shader variants execution rendering tasks
When, realize different effects, for tool example：
In the examples described above, drafting skin, drafting hair, drafting hair dew are all using #pragma multi_
The keyword of compile sentence definition it is assumed that each keyword is all in state of activation, then, when being compiled, is understood according to three
The different on off states of individual keyword are combined, and compiling generates different Shader variants, specifically it is assumed that each is crucial
Word has two kinds of on off states, represents that keyword is closed with 0, represents that keyword is in opening with 1, then above-mentioned
Shader in example instructs when being compiled, the different switch shapes of three keywords according to included in branch's anticipation sentence
State is combined, and can generate the individual Shader variant of following 8 (2^3), respectively：000th, 001,010,011,100,101,110 with
And 111.
As can be seen that Shader instruction adopts this write method from above-mentioned example, for weight in instructing in Shader
Use again and identical code (namely code of keyword), can only write once, when using by the activation of keyword
State control whether using, it is to avoid repeat to write identical code, thus for writing and safeguarding that offer facilitates.
In application development compilation process, the quantity of Shader variant exponentially can increase with the increase of keyword
Plus, for example：In certain application program Shader instruction, the quantity of keyword is 128, then Shader variant in compilation process
It is up to 2^128 in theory, then after compiling, the packet of this application program will be very big, then running this application program
When also by internal memory larger for occupied terminal, but have in the Shader variant being compiled in compilation process most of may can't
Using arriving, this is accomplished by the Shader variant that will not use is deleted.
The Shader variant not used is deleted generally by the mode deleting Keyword in prior art,
Specifically, Unity supports using #pragma shader_feature sentence, keyword to be deleted in Shader, but
Be this sentence when being used together with #pragma multi_compile sentence, the invalid switch of keyword can only be deleted
State, namely delete certain on off state of not using of keyword, the Shader variant not used can not be deleted completely, lead
Cause in the case that keyword quantity is more, the packet after compiling is still very big, occupied terminal larger internal memory during operation.
Therefore, need a kind of preprocess method of code to be compiled at present badly, to carry out to Shader instruction before compiling
Pretreatment, reduces the quantity generating Shader variant in compilation process, thus generating the size of packet after reducing compiling, fall
The tag memory taking during low operation.
Content of the invention
For in prior art, when being compiled to Shader instruction, the quantity of Shader variant can be with Shader
The increase of keyword in instruction and in exponential increase, and it is impossible to effective delete not by way of deleting to keyword
The Shader variant using, thus the packet of generation is larger after leading to compile, during operation, the larger internal memory of occupied terminal asks
