Hi all,
I ran into a GLSL error when run my GLSL shader. I use Mesa llvm driver.
The following is the error message I got:

Any idea how to track down the problem? Is it possible to generate TGSI
IR code with Mesa glsl_compiler?
The GLSL code is translated to an IR which is then translated to TGSI.
Hard to say what the problem is without seeing your shader code.
Can you file a bug which includes your shader code? If you could set it
up in a piglit shader_runner file that'd help.
