current upstream crash at : 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.

take test.ll

  define <vscale x 4 x i1> @icmp_undef() {
    %r = icmp eq <vscale x 4 x i32> undef, undef
    ret <vscale x 4 x i1> %r
  }

run : ./bin/opt -S -constprop t.ll -o -
