[PATCH] D61419: Support FNeg constant folding

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/test/CodeGen/X86/fp-fold.ll:226-242
+
+define float @fneg_undef() {
+; ANY-LABEL: fneg_undef:
+; ANY:       # %bb.0:
+; ANY-NEXT:    retq
+  %r = fneg float undef
+  ret float %r
----------------
These tests don't really belong in codegen (same for the vector cases).

Can you also add a test with some weird constant expressions as a source?
