Hello,
I am writing a MachineFunctionPass that inspects the generated machine code, and examines each opcode and its corresponding operands. If the 'instruction + operands' match a particular sequence, then the pass should replace them with a fixed instruction + operands sequence. I tried using MachineInstr's getOpcode and getOperand functions but the pass didn't work as expected.
Kindly tell me how to proceed or point to appropriate references. Thank you !
