[PURPOSE]:
The current process design for Uniform / Block / Pipe IO symbols reflection (during program linking) is as following :
1.1 using a global mapper called 'TNameToIndex' to store all the relationship of name (of symbols) to their indexes (in their own MapIndexToReflection vectors).
1.2 TNameToIndex mapper will be used during program linking and helps to check and merge duplicate symbols within each stage ( Uniform, Block and Pipe IO)
1.3 Different types of symbols will have their own index mapping storage. All those symbols will share TNameToIndex as a general searching mapper.
1.4 Only IN in first stage and OUT in last stage will be dealed within traversing functions.
Now, here we meet those problems:
2.1 In and Out variables for pipelines are mapping to different MapIndexToReflection vector (ioItems), but they may still have same names within the general symbol search mapper : TNameToIndex.
2.2 Then, when there are same symbols of IN in VS and OUT in FS, TNameToIndex could not tell the difference because it only stores one local index for one symbol (1:1) as a pair of KeyValue.
[What fixed]:
Seperate I/O from other symbols like Uniform and Block (it is wrong to keep them all in TNameToIndex), and save in new searching mappers called pipeInNameToIndex and pipeOutNameToIndex.
Expose new top-level functions defined as getReflectionPipeIOIndex and getPipeIOIndex for users who need to query Pipe I/O information (As they may reach those things through getUniformIndex and getReflectionIndex now, which is a confused way.)
As there are 2 mappers for above symbols, users needs to input second argument when they wanna reach those pipe I/O parameters, that's also why we need to modify GET functions either.
[Test Case]:
The shader is as following:
######### VS ############
layout(location = 0) in vec4 g_position;
layout(location = 1) in vec4 g_color;
out StageData {
vec4 color;
} g_vs_out;
void main() {
gl_Position = g_position;
g_vs_out.color = g_color;
}
########### FS #############
in StageData {
vec4 color;
} g_fs_in;
layout(location = 0) out vec4 g_color;
void main() {
g_color = g_fs_in.color;
