* Followup on Proposal to move MIR physical register namespace to '$' sigil.Puyan Lotfi2018-01-311-1/+1
| | | | | | | | | | | | Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
* [MIR] Print on the given output instead of stderr.Quentin Colombet2016-07-131-1/+1
| | | | | | | | | | | | Currently the MIR framework prints all its outputs (errors and actual representation) on stderr. This patch fixes that by printing the regular output in the output specified with -o. Differential Revision: http://reviews.llvm.org/D22251 llvm-svn: 275314
* When printing MIR, output to errs() rather than outs().Justin Lebar2016-02-191-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Without this, this command $ llvm-run llc -stop-after machine-cp -o - <( echo '' ) outputs an error, because we close stdout twice -- once when closing the file opened for "-o", and again when closing outs(). Also clarify in the outs() definition that you can't ever call it if you want to open your own raw_fd_ostream on stdout.
