[PATCH] D110065: [AArch64] Add support for the 'R' architecture profile.

[John Brawn via Phabricator via cfe-commits]

john.brawn added a comment.

Looking at the behaviour of gcc it looks like there -march=armv8-r enables instructions that are present in 8-r but not 8-a, but doesn't disable any instructions. So e.g. it will accept the dcps3 instruction when compiling with -march=armv8-r whereas clang won't. That's probably a bug in gcc though.
