[LLVMdev] get the identifies of the unnamed temporaries from the instruction of LLVM IR
hello guys:
I am in trouble with get the identifies of the unnamed temporaries from the
instruction of LLVM IR.
for example:
instruction: %4 = mul nsw i32 %1, %width
unnamed temporaries: %4, %1
how to get them?
I have tried several iterators(op_iterator,value_op_iterator) and
getOperand(int) function,but none of them works.
does anyone know how to get it? thanks very much
