2014-05-30	fix breakage from recent syscall commits due to missing errno macros	Rich Felker	1	-0/+1

2014-05-29	support linux kernel apis (new archs) with old syscalls removed	Rich Felker	1	-4/+12
	such archs are expected to omit definitions of the SYS_* macros for syscalls their kernels lack from arch/$ARCH/bits/syscall.h. the preprocessor is then able to select the an appropriate implementation for affected functions. two basic strategies are used on a case-by-case basis: where the old syscalls correspond to deprecated library-level functions, the deprecated functions have been converted to wrappers for the modern function, and the modern function has fallback code (omitted at the preprocessor level on new archs) to make use of the old syscalls if the new syscall fails with ENOSYS. this also improves functionality on older kernels and eliminates the incentive to program with deprecated library-level functions for the sake of compatibility with older kernels. in other situations where the old syscalls correspond to library-level functions which are not deprecated but merely lack some new features, such as the *at functions, the old syscalls are still used on archs which support them. this may change at some point in the future if or when fallback code is added to the new functions to make them usable (possibly with reduced functionality) on old kernels.
2013-03-26	remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG	Rich Felker	1	-1/+2
	the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part.
2012-09-07	cleanup src/linux and src/misc trees, etc.	Rich Felker	1	-0/+27
	previously, it was pretty much random which one of these trees a given function appeared in. they have now been organized into: src/linux: non-POSIX linux syscalls (possibly shard with other nixen) src/legacy: various obsolete/legacy functions, mostly wrappers src/misc: still mostly uncategorized; some misc POSIX, some nonstd src/crypt: crypt hash functions further cleanup will be done later.
