Subject: aarch64: Mark rev64 as a pseudo instruction
X-Git-Tag: binutils-2_45~640
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a8d71f52d0729376ff1dfa27a60a07cc8d4dff40;p=thirdparty%2Fbinutils-gdb.git

aarch64: Mark rev64 as a pseudo instruction

This is more natural than raising the priority of rev with F_P1, and
is functionally equivalent.
