+; 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)
