Detailed Description

template<bool Signed>
class clang::interp::IntegralAP< Signed >

If an IntegralAP is constructed from Memory, it DOES NOT OWN THAT MEMORY.

It will NOT copy the memory (unless, of course, copy() is called) and it won't alllocate anything. The allocation should happen via InterpState or Program.
