[PATCH] D21408: [ARM] MRRC2 shouldn't allow predicates

[Renato Golin via llvm-commits]

Hi Ranjeet,

I'm surprised you didn't pick this problem before commit. Our buildbots seem happy, so this was definitely a downstream test.

Both my AArch32 and ARMv7M manuals seem to imply AL is allowed for MRRC2, but the ARMv7A manual says it must be unconditional (which following certain interpretations, could mean using AL).

Can you share what the assertion is?

cheers,
