[RDF] Clear the renamable flag when copy propagating reserved registers llvm-svn: 323831
2018-01-31 07:19:44 +08:00
# RUN: llc -march=hexagon -run-pass hexagon-rdf-opt %s -o - | FileCheck %s
# Check that r29 gets propagated into the A2_addi, and that the renamable
# flag is cleared.
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
