[PATCH] D93793: [IR] Let IRBuilder's CreateVectorSplat/CreateShuffleVector use poison as placeholder

[Juneyoung Lee via Phabricator via llvm-commits]

aqjune added inline comments.


================
Comment at: clang/test/CodeGen/SystemZ/builtins-systemz-zvector-constrained.c:84
   vd = vec_splat(vd, 1);
   // CHECK: shufflevector <2 x double> %{{.*}}, <2 x double> undef, <2 x i32> <i32 1, i32 1>
   // CHECK-ASM: vrepg
----------------
These SystemZ zvector tests are still creating shufflevector with undef, and I couldn't find where they stem from. :/
