Subject: [AArch64] Add V8_2aOps feature to Cortex-A55 and 75
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=df2a024df200fcc986d7f46adf57f2db7cff8bf7;p=llvm

[AArch64] Add V8_2aOps feature to Cortex-A55 and 75

Add the missing hardware features the ProcA55 and ProcA75 feature.
These are already enabled via the target parser, but I had missed
them in the backend.

Differential Revision: https://reviews.llvm.org/D37974
