Damien Lespiau b3ba758a01 uxa/gen7: Don't use a message register to store vl ... Turns out the "new" assembler that uses mesa's opcode emission hits the path that automatically transforms MRF registers into GRF ones in the exa_wm_src_projective shader. The diff with the new assembler is: $ intel-gen4disasm -g7 - - { 0x00600041, 0x208077be, 0x008d03c0, 0x008d0180 }, + { 0x00600041, 0x2e8077bd, 0x008d03c0, 0x008d0180 }, mul(8) m4<1>F g30<8,8,1>F g12<8,8,1>F { align1 }; mul(8) g116<1>F g30<8,8,1>F g12<8,8,1>F { align1 }; Of course, message registers are no more in gen7, so the shader is trying to do something shaddy (ahem!). Instead of using m4, let's make exa_wm_src_projective use g68 for v (aka vl) which makes sense since: 1/ vh is g69 2/ exa_wm_src_affine uses g68 for vl already This commit changes the generated assembly, here's the decoded diff: $ intel-gen4disasm -g7 - - { 0x00600041, 0x208077be, 0x008d03c0, 0x008d0180 }, + { 0x00600041, 0x288077bd, 0x008d03c0, 0x008d0180 }, mul(8) m4<1>F g30<8,8,1>F g12<8,8,1>F { align1 }; mul(8) g68<1>F g30<8,8,1>F g12<8,8,1>F { align1 }; Cc: Kenneth Graunke <kenneth@whitecape.org> Reported-by: Xiang, Haihao <haihao.xiang@intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>		2013-02-18 13:46:47 +00:00
