[PATCH] D142313: [PowerPC] Replace PPCISD::VABSD cases with generic ISD::ABDU(X,Y) node

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/CodeGen/PowerPC/ppc64-P9-vabsd.ll:1249
 entry:
   %sub = sub <4 x i32> %a, %b
   %sub.i = sub <4 x i32> zeroinitializer, %sub
----------------
if we replace this with sub nsw then the fold is legal
