[PATCH] D141836: [AArch64] Disable __muloti4 libcalls for AArch64

[Sebastian Poeplau via Phabricator via llvm-commits]

sebastianpoeplau added a comment.

> From reading the thread on https://github.com/llvm/llvm-project/issues/16778 (which is closed, although the issue doesn't seem resolved), this is a stop-gap for toolchains that don't include an implementation for `__muloti4`. An implementation seems to exist in compiler-rt, but compiler-rt isn't linked with by default. It seems unfortunate that there is no way to still emit a call to `__muloti4` when we do link with compiler-rt, but from reading that thread there is currently no way to tell LLVM that an implementation of `__muloti4` is available.

That's my understanding as well.

> So I'm happy to accept this change, but please wait for a few days to land it to see if @rengolin or @nickdesaulniers has any comments.

Will do. Thanks for your review!
