[llvm] r326795 - [Asm] Add debug printing for assembler macros

[Oliver Stannard via llvm-commits]

Ah, yep, I've added a dependency from MC to MCParser, which is the wrong way round. I think I should just be able to move the calls from MCContext to AsmParser to fix this.

Thanks for letting me know, for some reason I didn't get any emails from those bots.
