* Followup on Proposal to move MIR physical register namespace to '$' sigil.Puyan Lotfi2018-01-311-17/+17
| | | | | | | | | | | | Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
* [CodeGen] Always use `printReg` to print registers in both MIR and debugFrancis Visoiu Mistrih2017-11-301-3/+3
| | | | | | | | | | | | | | output As part of the unification of the debug format and the MIR format, always use `printReg` to print all kinds of registers. Updated the tests using '_' instead of '%noreg' until we decide which one we want to be the default one. Differential Revision: https://reviews.llvm.org/D40421 llvm-svn: 319445
* Add test case for r311511Matthias Braun2017-08-231-0/+36
This also changes the TailDuplicator to be configured explicitely pre/post regalloc rather than relying on the isSSA() flag. This was necessary to have `llc -run-pass` work reliably. llvm-svn: 311520
