llvm dev - May 2009 - [LLVMdev] new warnings

I discovered I needed:

              bool Emitted = TII->copyRegToReg(*mbbi, mi, regA, regB,  
rc, rc);

              assert(Emitted && "Unable to issue a copy
instruction!
\n");
            }

in a release-asserts build to get around a warning:

/Volumes/mrs5/net/clang/clang/clang/lib/CodeGen/ 
TwoAddressInstructionPass.cpp: In member function ‘virtual  
bool<unnamed>::TwoAddressInstructionPass::runOnMachineFunction 
(llvm::MachineFunction&)’:
/Volumes/mrs5/net/clang/clang/clang/lib/CodeGen/ 
TwoAddressInstructionPass.cpp:937: warning: unused variable ‘Emitted’

I can't recall if that is the recommended way to fix these types of  
errors, so I thought I'd ask here first.
