[PATCH] D87279: [clang] Fix handling of physical registers in inline assembly operands.

[James Y Knight via Phabricator via cfe-commits]

jyknight added a comment.

This change seems like it's done in the wrong layer -- why do we add a special-case in Clang to emit "={r11},{r11}", instead of fixing LLVM to not break when given the previously-output "={r11},0"?

Furthermore, since earlyclobber was exempted from this change, doesn't the same TwoAddressInstructionPass bug still affect earlyclobber uses?
