11// CAREFUL: In programs with plugins, FuncPC* can return different values
12// for the same function (because there are actually multiple copies of
13// the same function in the address space). To be safe, don't use the
14// results of this function in any == expression. It is only safe to
15// use the result as an address at which to start executing code.
