; 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)
