--- Comment #2 from Marius Hillenbrand <mhil...@linux.ibm.com> ---
Per Sanjay Patel's comment on https://reviews.llvm.org/D94089
> I'm sympathetic to the motivation, but that was a hack: one goal of IR is to
> overcome side-channel source-level optimization like this.
> For example, we added several IR transforms to reduce compiled-code
> differences
> in source-level diffs like "if (bool1 && bool2)" vs. "if (bool1 & bool2)"
> (logical vs. bitwise ops).
> If the expression order matters, then we want the programmer to indicate that
> explicitly with something like "__builtin_expect" or profile metadata.
... closing this bug as no-issue.
