[llvm-dev] Conversion of const llvm::MCExpr * to string

[hameeza ahmed via llvm-dev]

Thank you. I did as you mentioned. Now i am getting error because MAI is
not defined in my code. I am adding the print statement in
x86mccodeemitter.cpp.

string imm;
llvm::raw_string_ostream rso(imm);

MI.getOperand(4).getExpr()->print(rso, MAI);

getting error. What to do now?

Please help.
