Subject: AArch64: disable printing of add/sub alias
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=61e0d55d0e8825d945b7133a076918089b548530;p=oota-llvm.git

AArch64: disable printing of add/sub alias

This alias appears not to have an appropriate PrintMethod. Normally, I'd look
into it, but since AArch64 is disappearing soon it's probably not worth it.

This will be tested when the TableGen "should I print this Alias" heuristic is
fixed (very soon).
