this is definitely the most perverted, obscene thing i've ever done with a compiler. to my friends who work at Apple, have worked at Apple, or are possessed of such a shining divine Purpose that they have accumulated more Apple knowledge than any Apple employee could possibly know… you're allowed to kill me for this. well not really but
good news for stack smashers, the safety's off https://github.com/hikari-no-yume/touchHLE/commit/2960cf6260520685da39379803643ee4d82ec4ec
I am now cross-compiling to 32-bit iOS using upstream LLVM and no Apple headers, on Windows!
fear me

note: the resulting binary probably doesn't actually work on iOS, only in touchHLE. I could make it work on iOS but it would require some extra effort and I don't have a jailbroken iOS 6 device right now :)
@mary I've thought about trying it with no_std before… never actually done it though.
@saagar i'm sorry saagar, you can't fire that gun. i have left the trigger undefined
@saagar on that note I find it funny that I had to disable stack smashing protection because the stack guard was undefined :3
