[PATCH v4 2/3] aarch64: Add support for moving fpm system register

2024-07-30 Thread Claudio Bantaloukas
Unlike most system registers, fpmr can be heavily written to in code that exercises the fp8 functionality. That is because every fp8 instrinsic call can potentially change the value of fpmr. Rather than just use an unspec, we treat the fpmr system register like all other registers and use a move o
