* | Followup on Proposal to move MIR physical register namespace to '$' sigil. | Puyan Lotfi | 2018-01-31 | 1 | -3/+3 |
| | | | | | | | | | | | | Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922 | ||||
* | [MachineOperand][MIR] Add isRenamable to MachineOperand. | Geoff Berry | 2017-12-12 | 1 | -0/+16 |
Summary: Add isRenamable() predicate to MachineOperand. This predicate can be used by machine passes after register allocation to determine whether it is safe to rename a given register operand. Register operands that aren't marked as renamable may be required to be assigned their current register to satisfy constraints that are not captured by the machine IR (e.g. ABI or ISA constraints).
