Sure, but let's replace this with a link to a bug report in llvm's issue tracker?Yes, please! I can apply the patch once we have the bug number.I can look into that.https://github.com/llvm/llvm-project/issues/215547
Thanks. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106671 was closed as invalid pointing to the same commit in llvm. What's going on here? Where's the corresponding feature request for GCC? At the least, I could imagine there being a `-fno-omit-bti-pads` or whatever for the kernel to opt into this behavior. -- Thanks, ~Nick Desaulniers
