Hi All,

I have ADD instruction but I want change to SUB instruction in MachineCSE.cpp file.

%8:gpr32 = MOVi32imm -655360000
nsw ADDWrr killed %7:gpr32, killed %8:gpr32

%8:gpr32 = MOVi32imm 655360000
nsw SUBSWrr killed %7:gpr32, killed %8:gpr32

Could any one please give your suggestions on this.

Thanks and Regards,
Ramakota Reddy.
