Subject: aarch64: Make FEAT_ASMv8p2 instruction aliases always available
X-Git-Tag: binutils-2_42~93
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f6cfacfed1fd604bea8fd95324f245e10a322320;p=thirdparty%2Fbinutils-gdb.git

aarch64: Make FEAT_ASMv8p2 instruction aliases always available

There's no reason to disallow the aliases when the aliased instructions are
always available.  The new behaviour matches existing LLVM behaviour.
