llvm dev - Mar 2009 - [LLVMdev] how to get the InvodInst 's Operand Name?

HI all,


here is a llvm IR :

invoke void @__cxa_throw(i8* %7, i8* bitcast
(%struct.__fundamental_type_info_pseudo* @_ZTIi to i8*), void (i8*)*
null)
noreturn         to label %invcont unwind label %lpad

say I want to get the Invoke's Operand's  name,  I use
getOperand(i)->getName(), it can work for that the Operand hasname,
but  some Operand  hasn't name,
So, My problem is how can i get  all the Operand 's name ?

are you trying to get the name "@_ZTIi" or "@__cxa_throw"?

Ciao,

Duncan.

Hi Duncan,
>>are you trying to get the name "@_ZTIi" or
"@__cxa_throw"?
yes! i want get the name @_ZTi or @__cxa_throw,
the latter @__cxa_throw i can get it throw  value->getName(), but the
 @_ZTi it  did n't has  name!
