#91870 fixes a warning that's existed for a while for bare-metal Arm targets which encourages calling interrupt handlers from other interrupt handlers. Doing this leads to unpredictable behavior and/or infinite loops due to how Arm exception returns are defined: https://github.com/llvm/llvm-project/pull/91870#issuecomment-2106045679. `clang` should warn when you try to do this.
