Hi Tim and Alex Thanks for your replies. So just to make it clear for me: does this imply that there’s indeed no way on the current version to tell the compiler or Clang to optimize this?

It may be that the 'not' operator is not being found under bash at : 'RUN: at line 12';   not Perhaps this is would be better as the more commonly seen '!'.

I've come across a curious and pernicious problem in llvm-rc. absolute.test checks that llvm-rc can accept a filename that is an absolute path. And it works just fine. Until you run it with a file that starts with "/c." These will fail: llvm-rc /crawl/through/some/path/to/my.rc llvm-rc /c/some/path/to/my.rc The option parser ends up interpreting "/" as an option prefix

Hi, we at Arm have noticed that assembly can differ when compiling for AArch64 depending on whether debug information is generated or not. The issue is reproducible for the following small example compiled with `-O1` for `aarch64-arm-linux-gnu`: a() { b(a); for (;;) c("", b); } The reason for the difference is that AArch64 frame lowering emits CFI
