Rich Felker	ffaaa6d230	remove legacy i386 fallback stdarg implementation and framework this has been slated for removal for a long time. there is fundamentally no way to implement stdarg without compiler assistance; any attempt to do so has serious undefined behavior; its working depends not just (as a common misconception goes) on ABI, but also on assumptions about compiler code generation internal to a translation unit, which is not subject to external ABI constraints.	10 years ago
Rich Felker	def0af1898	use compiler builtins for variadic macros when available this slightly cuts down on the degree musl "fights with" gcc, but more importantly, it fixes a critical bug when gcc inlines a variadic function and optimizes out the variadic arguments due to noticing that they were "not used" (by __builtin_va_arg). we leave the old code in place if __GNUC__ >= 3 is false; it seems like it might be necessary at least for tinycc support and perhaps if anyone ever gets around to fixing gcc 2.95.3 enough to make it work..	15 years ago
