Built-In Functions Provided by GCC

shame we dont do more cool stuff with builtins. so many times ive wished for something like

__builtin_regex_compile() __builtin_regex_match()

regexes don't generally belong as compiler builtins. Those are more suitable for language standard libraries or OS standards like POSIX.

If there were an ISA out there that had some kind of regular expression feature, those could conceivably be supported with builtins, though.

		The dividing line between compiler builtin, language primitive, standard library or compiler runtime doesn't really exist if you don't want it to. They're all variations on the same theme.

I wonder how one would do DFA minimization with that though. Implement regexp functional equivalence testing so I will not have to! :D

That could be implemented as a pass you load yourself if you don't want to to wait / persuade other people to ship it.
