gcc, Arm: Revert changes to {get,set}_fpscr
MVE made changes to {get,set}_fpscr to enable the compiler to optimize unneccesary gets and sets when using these for intrinsics that use and/or write the carry bit. However, these actually get and set the full FPSCR register and are used by fp env intrinsics to modify the fp context. So MVE should not be using these. gcc/ChangeLog: 2020-03-20 Andre Vieira <andre.simoesdiasvieira@arm.com> * config/arm/unspecs.md (UNSPEC_GET_FPSCR): Rename this to ... (VUNSPEC_GET_FPSCR): ... this, and move it to vunspec. * config/arm/vfp.md: (get_fpscr, set_fpscr): Revert to old patterns.
