Googling about the hp libunwind, it sounds like it's a series of unw_ functions. Which sounds like the GCC libunwind interface. But that is vibes; if someone *believes* the two are API incompatible, *what could I tell them to convince them otherwise*?

Also, is it weird that llvm libunwind seems to literally has no usage documentation at all? Did I miss something? Is Google simply cooked?
