clang-p2996/llvm/test/CodeGen/X86/vec_fabs.ll
Craig Topper cdb0ed2910 [X86] Add custom execution domain fixing for 128/256-bit integer logic operations with AVX512F, but not AVX512DQ. 
AVX512F only has integer domain logic instructions. AVX512DQ added FP domain logic instructions.

Execution domain fixing runs before EVEX->VEX. So if we have AVX512F and not AVX512DQ we fail to do execution domain switching of the logic operations. This leads to mismatches in execution domain and more test differences.

This patch adds custom domain fixing that switches EVEX integer logic operations to VEX fp logic operations if XMM16-31 are not used.

; PR20354: when generating code for a vector fabs op,
; make sure that we're only turning off the sign bit of each float value.
; No constant pool loads or vector ops are needed for the fabs of a
; bitcasted integer constant; we should just return an integer constant
; that has the sign bits turned off.
;
; So instead of something like this:
; movabsq (constant pool load of mask for sign bits)
; vmovq (move from integer register to vector/fp register)
; vandps (mask off sign bits)
; vmovq (move vector/fp register back to integer return register)
;
; We should generate:
; mov (put constant value in return register)
