Puyan Lotfi	43e94b15ea	Followup on Proposal to move MIR physical register namespace to '$' sigil. ... Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922	2018-01-31 22:04:26 +00:00
Francis Visoiu Mistrih	c71cced0aa	[CodeGen] Always use `printReg` to print registers in both MIR and debug ... 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.

Jonas Paulsson	c63ed222b8	[SystemZ] Enable machine scheduler. ... The machine scheduler (before register allocation) is enabled by default for SystemZ. The SelectionDAG scheduling preference now becomes source order scheduling (was regpressure). Review: Ulrich Weigand https://reviews.llvm.org/D37977 llvm-svn: 315063	2017-10-06 13:59:28 +00:00
