[PATCH] D150249: [X86] Improve handling on zero constant for fminimum/fmaximum lowering

[Evgenii Kudriashov via Phabricator via llvm-commits]

e-kud added inline comments.


================
Comment at: llvm/test/CodeGen/X86/fminimum-fmaximum.ll:1140
 ; X86-NEXT:    retl
   %r = call <2 x double> @llvm.minimum.v2f64(<2 x double> %x, <2 x double> <double 0., double 5.>)
   ret <2 x double> %r
----------------
I think this test shows that a predicate //is not preferred zero// should be more generic than // is opposite zero// (in context of constant vectors).
