[LLVMdev] A weird problem when try to output operand of instruction involving function pointer in a struct

names of local variables/registers have no meaning in LLVM (in fact they aren't
required to have a name at all) they only exist to make things more readable for
developers.  If you try to name something XYZ, but something called XYZ already
exists, then XYZ1 will be used instead; if the XYZ1 name is already used, then
XYZ2 will be used instead, etc.  Due to the way front-ends work it is quite
common to have such name collisions, resulting in getting a name with a number
on the end.

Ciao, Duncan.
