* Followup on Proposal to move MIR physical register namespace to '$' sigil.Puyan Lotfi2018-01-311-7/+7
| | | | | | | | | | | | Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922

* [Hexagon] Don't kill live registers when creating mux out of tfrKrzysztof Parzyszek2017-06-161-0/+17
The second part of r305300: when placing the mux at the later location, make sure that it won't use any register that was killed between the two original instructions. Remove any such kills and transfer them to the mux. llvm-svn: 305553
