[Mesa-dev] [PATCH] r600g: fix and optimize tgsi_cmp when using ABS and NEG modifier

From: Patrick Rudolph Some apps set NEG and ABS on the source param to test for zero. Use ALU_OP3_CNDE insted of ALU_OP3_CNDGE and unset both modifiers. It also removes the need for a MOV instruction, as ABS isn't supported on op3. Tested on AMD CAYMAN and AMD RV770. Signed-off-by: Patrick Rud
