llvm dev - Apr 2013 - [LLVMdev] get the identifies of the unnamed temporaries from the instruction of LLVM IR

hi, Duncan:
thanks for your patience.
i have tried it. 
using instuction: errs()<<i->getOperand(0);
but it prints the address: someting like 0x1139700;
i checked the defination of getOperand() is Value* getOperand( unsigned int
i);
so is there someting i missed?

You can also use: i->getOperand(0)->dump();

Ciao, Duncan.

hi, Duncan,
thank you for your reply;
instruction "i->getOperand(0)->dump()" may print the %4 in the
screen, but
how can i store it in a variable like char * oprand="%4" ?
