[LLVMdev] Dereference PointerType?

Hi Daniel,

it is useless because getTypeAllocSize will handle any type, including
pointer types.  It is bogus because your code assumes that the LLVM
bitcode is targeting your own machine, i.e. that sizeof(void*) as given
by your machine is correct for the target.  This may or may not be the
case, but it is something best avoided.

Ciao,

Duncan.
