[PATCH] D71389: [ConstantFold][SVE] Fix constant folding for bitcast.

[Huihui Zhang via Phabricator via llvm-commits]

huihuiz added a comment.

Current upstream crash with llvm/lib/IR/Value.cpp:404: void llvm::Value::doRAUW(llvm::Value *, llvm::Value::ReplaceMetadataUses): Assertion `New->getType() == getType() && "replaceAllUses of value with new value of different type!"' failed.

run: opt -S -constprop bitcast.ll -o -

bitcast.ll

  define <vscale x 4 x float> @bitcast_scalable_constant() {
    %i1 = insertelement <vscale x 4 x i32> undef, i32 1, i32 0
    %i2 = shufflevector <vscale x 4 x i32> %i1, <vscale x 4 x i32> undef, <vscale x 4 x i32> zeroinitializer
    %i3 = bitcast <vscale x 4 x i32> %i2 to <vscale x 4 x float>
    ret <vscale x 4 x float> %i3
