2016-01-26	change the internal socketcall selection logic	Szabolcs Nagy	-0/+2
	only use SYS_socketcall if SYSCALL_USE_SOCKETCALL is defined internally, otherwise use direct syscalls. this commit does not change the current behaviour, it is preparation for adding direct syscall numbers for i386.
2015-04-14	use hidden visibility for i386 asm-internal __vsyscall symbol	Rich Felker	-7/+7
	otherwise the call instruction in the inline syscall asm results in textrels without ld-time binding.
2014-06-06	add vdso clock_gettime acceleration support to i386	Rich Felker	-0/+4

2014-04-17	make socketcall types common as they are same for all architectures	Timo Teräs	-22/+0

2013-03-26	remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG	Rich Felker	-2/+0
	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.
2012-10-13	ensure pointer decay in inline-asm arg for i386 syscall6	Rich Felker	-1/+1
	this is actually a rather subtle issue: do arrays decay to pointers when used as inline asm args? gcc says yes, but currently pcc says no. hopefully this discrepency in pcc will be fixed, but since the behavior is not clearly defined anywhere I can find, I'm using an explicit operation to cause the decay to occur.
2012-10-11	i386 vsyscall support (vdso-provided sysenter/syscall instruction based)	Rich Felker	-66/+7
	this doubles the performance of the fastest syscalls on the atom I tested it on; improvement is reportedly much more dramatic on worst-case cpus. cannot be used for cancellable syscalls.
2012-09-08	syscall organization overhaul	Rich Felker	-0/+136
	now public syscall.h only exposes __NR_* and SYS_* constants and the variadic syscall function. no macros or inline functions, no __syscall_ret or other internal details, no 16-/32-bit legacy syscall renaming, etc. this logic has all been moved to src/internal/syscall.h with the arch-specific parts in arch/$(ARCH)/syscall_arch.h, and the amount of arch-specific stuff has been reduced to a minimum. changes still need to be reviewed/double-checked. minimal testing on i386 and mips has already been performed.
