How can I print to a string in LLVM

问题

I want to print an instruction in LLVM to a string instead of the screen. I use I->print( errs() ) to print to the screen. How can I instead put the instruction in a string?

回答1:

Like this,

std::string str;
llvm::raw_string_ostream rso(str);
I->print(rso);
