Subject: RISC-V: Add vxsat as a register

X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f6d7ff4796709c0639317bfd8fa58a2957a1e299;p=thirdparty%2Fgcc.git

RISC-V: Add vxsat as a register

We aren't doing anything with vxsat right now, but I'd like to add it as
an accepted register to the clobber list.  If we get this into GCC-14
then we'll avoid some preprocessor-based twiddling if we ever start
using vxsat in the future.

gcc/ChangeLog:

	* config/riscv/riscv.h (REGISTER_NAMES): Add vxsat.
