Rich Felker	867b1822f3	add explicit barrier operation to internal atomic.h API	12 years ago
Rich Felker	90e51e45f5	clean up unused and inconsistent atomics in arch dirs the a_cas_l, a_swap_l, a_swap_p, and a_store_l operations were probably used a long time ago when only i386 and x86_64 were supported. as other archs were added, support for them was inconsistent, and they are obviously not in use at present. having them around potentially confuses readers working on new ports, and the type-punning hacks and inconsistent use of types in their definitions is not a style I wish to perpetuate in the source tree, so removing them seems appropriate.	12 years ago
rofl0r	323272db17	import vanilla x86_64 code as x32	13 years ago
Rich Felker	50a50988d5	remove more unnecessary operand-size suffixes from x86_64 atomic.h	13 years ago
Rich Felker	311736516e	remove gratuitous temp vars, casts, and suffixes in x86_64 atomic.h aside from general cleanup, this should allow the identical atomic.h file to be used for the upcoming x32 port.	13 years ago
Rich Felker	df0b5a4940	security hardening: ensure suid programs have valid stdin/out/err this behavior (opening fds 0-2 for a suid program) is explicitly allowed (but not required) by POSIX to protect badly-written suid programs from clobbering files they later open. this commit does add some cost in startup code, but the availability of auxv and the security flag will be useful elsewhere in the future. in particular auxv is needed for static-linked vdso support, which is still waiting to be committed (sorry nik!)	15 years ago
Rich Felker	4bb9b4f3b4	add word-sized ctz function to atomic.h strictly speaking this and a few other ops should be factored into asm.h or the file should just be renamed to asm.h, but whatever. clean it up someday.	15 years ago
Rich Felker	e914f8b7ec	optimize contended normal mutex case; add int compare-and-swap atomic	15 years ago
Nicholas J. Kain	062354f2e1	Optimize x86_64 atomics to take advantage of 64-bitness.	15 years ago
Nicholas J. Kain	1e12632591	Port musl to x86-64. One giant commit!	15 years ago
Rich Felker	a5bf06c035	move arch-specific internal headers into place	15 years ago
Rich Felker	0bcbb53dc4	ensure that the compiler doesn't try to reorder around atomic ops	15 years ago
Rich Felker	0b44a0315b	initial check-in, version 0.5.0	15 years ago
