[PATCH] D80538: [MachineVerifier] Add a new RewriteTied flag to fix verify two-address constraint error

[Zhang Kang via Phabricator via llvm-commits]

ZhangKang added a comment.

The TwoAddressInstructionPass will rewrite the tied to meet the RegConstraint.
For example:
The TwoAddressInstructionPass will rewrite below IR

  %10:gprc = RLWIMI killed %9:gprc(tied-def 0), killed %0:gprc, 1, 0, 30

to:

  %10:gprc = RLWIMI killed %10:gprc(tied-def 0), killed %0:gprc, 1, 0, 30
