Not yet compliant, but working on it. There's quite a few ASIL-D components too. We don't use GCC but rather tip-of-the-tree LLVM. Embedded is a completely separate and different mess using whatever the vendor ships for a particular microcontroller.

So far our safety guys haven't seen any issues with tool qualification besides requiring everything to be documented and the whole system to be re-tested in case of any tool changes.
