[PATCH] D54368: RegAllocFast: Record internal state based on register units

[Mikael Holmén via Phabricator via llvm-commits]

uabelho added inline comments.


================
Comment at: llvm/lib/CodeGen/RegAllocFast.cpp:136
     void setPhysRegState(MCPhysReg PhysReg, unsigned NewState);
+    bool isPhysRegFree(MCPhysReg PhysReg) const;
 
----------------
This seems to be unused? gcc warns with

../lib/CodeGen/RegAllocFast.cpp:245:6: warning: 'bool {anonymous}::RegAllocFast::isPhysRegFree(llvm::MCPhysReg) const' defined but not used [-Wunused-function]
 bool RegAllocFast::isPhysRegFree(MCPhysReg PhysReg) const {
      ^~~~~~~~~~~~

Will it be used soon or can it be removed?
