[Mesa-dev] glslcompiler build failure

We built a new standalone compiler as part of glsl2 - it should be built as
src/glsl/glsl_compiler. You might want to take a look at that. It takes a
--dump-ast ...prints out the abstract syntax tree (GLSL source)
--dump-hir ...prints out high level IR (before lowering & optimization)
--dump-lir ...prints out low lever IR (optimized)
--link ...attempts to link the given files
For testing an individual shader, you can just run:
glsl_compiler --dump-lir foo.frag
If you want to run piglit's glslparsertest using the standalone compiler,
create a symlink from piglit/tests/glslparsertest/glslcompiler ->
mesa/src/glsl/glsl_compiler. Then, run:
./piglit-run.py -x valgrind tests/external-glslparser.tests results
Of course, that only tests parsing...usually, if I want to test shader
execution, I'll create a new .shader_test file and use piglit's shader_runner.
I actually hadn't seen src/mesa/drivers/glslcompiler before. Is it worth
keeping? I imagine we could fold anything useful into the new compiler.
I hope this helps!
