    draw,gallivm: Fix draw_get_shader_param.
    
    - Use LLVM limits when LLVM is being used, instead of TGSI limits
    - Provide draw_get_shader_param_no_llvm for when llvm is never used (softpipe)
    - Eliminate several of the hacks around draw shader caps in several drivers
    
    Unfortunately the hack for PIPE_MAX_VERTEX_SAMPLERS is still necessary.

Comment 1 Jose Fonseca 2012-07-17 12:47:57 UTC 
Hi Vinson.

The test passes here with LLVM 3.1 on x86.

What's your setup?
Comment 2 Vinson Lee 2012-08-13 00:10:16 UTC 
I am unable to reproduce the failure. glsl-mat-from-int-ctor-03 passes with Mesa master.
