[LLVMdev] insertions with inst_iterators?

[ret val]

I insert a function call to a function I generate right before when I
find something "interesting", a assignment on a function pointer or a
call on a function pointer. So I don't think its anything inherit with
my algorithm, just my use of iterators.

I attached the main body of my loop incase anyone feels like taking a
look. When it runs it prints "here"(line 138) endlessly.

Thanks again
