[PATCH] D83937: [Power] Set the mayRaiseFPException for FCMPUS/FCMPUD

[Qiu Chaofan via Phabricator via llvm-commits]

qiucf added a comment.

Can we add test to show the effect? Something like

  %a = call double @llvm.experimental.constrained.fadd.f64(...)
  ; Insert the instruction here
  %b = call double @llvm.experimental.constrained.fdiv.f64(...)

I think instruction with side effect should prevent `fdiv` from scheduled upwards.
