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.

Eli Friedman	da228fee0c	[ARM] Use alias analysis in ARMPreAllocLoadStoreOpt. ... This allows the optimization to rearrange loads and stores more aggressively. This doesn't really affect performance, but it helps codesize. Differential Revision: https://reviews.llvm.org/D30839 llvm-svn: 298021	2017-03-17 00:34:26 +00:00
