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

[Jonas Paulsson via Phabricator via cfe-commits]

jonpa added a comment.

The problem seems to be with a tied earlyclobber operand:

  asm("" : "+&r"(a));

Per the comment in InlineAsm::ConstraintInfo::Parse(), only output can be earlyclobber.

I am not sure if the earlyclobber ('&') should with this patch be removed from the added use of the register, or if this has to for some reason really be tied to the def?
