GPU Shader Analyzer - Compilation Bug

Question asked by tobspr on Dec 18, 2015

I think I found a bug in the GPU Shader Analyzer (Version 1.59.3208). This GLSL fragment shader fails to compile with all available compilers:

 

#version 130

struct MyStruct {

  int member;

};

in SomeVertexInput {

  int member_2;

};

void main() {}

 

Error message:

 

Internal compilation failure. Possibly caused by GSA not supporting a GLSL feature used in shader.

ERROR: 0:7: error(#132) Syntax error: ';' parse error

ERROR: error(#273) 1 compilation errors.  No code generated

 

My first thought was, maybe the compiler does not support global struct declarations. However, this compiles just fine:

 

#version 130

struct MyStruct {

  int member;

};

void main() {}

 

So obviously thats not the issue. Only using the vertex input works fine, too, though:

 

#version 130

in SomeVertexInput {

  int member_2;

};

void main() {}

 

All three shaders compile with the NVIDIA drivers, but only the last 2 compile with GPU Shader Analyzer. Am I doing something wrong? Or did I discover a compiler bug?

 

(BTW, is there some way to format code?)
