Subject: [binutils][aarch64] Allow movprfx for SVE2 instructions.
X-Git-Tag: binutils-2_33~1300
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5cd99750959f54fea9e7290ec850df6c96878b56;p=thirdparty%2Fbinutils-gdb.git

[binutils][aarch64] Allow movprfx for SVE2 instructions.

SVE2 introduces a number of new instructions that work with the movprfx
instruction.  This commit ensures that SVE2 instructions are accounted
for.
