*	fcntl.h should make availabel the mode constants from sys/stat.h	Rich Felker	2011-03-08	2	-8/+20
\| \| \| \|	also remove some legacy nonsense that crept in.
*	simplify and optimize pthread_mutex_trylock	Rich Felker	2011-03-08	1	-17/+16
\|
*	rwlock trylock functions were wrongly returning EAGAIN instead of EBUSY	Rich Felker	2011-03-08	2	-3/+3
\|
*	fix major breakage in pthread_once (it was always deadlocking)	Rich Felker	2011-03-08	1	-8/+7
\| \| \| \| \| \|	the issue was a break statement that was breaking only from the switch, not the enclosing for loop, and a failure to set the final success state.
*	fix and optimize non-default-type mutex behavior	Rich Felker	2011-03-08	4	-25/+19
\| \| \| \| \| \| \| \| \|	problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time.
*	implement pthread_mutexattr_[gs]etpshared functions	Rich Felker	2011-03-08	2	-0/+16

\|
*	fix off-by-one error in sem_(timed)wait (using old sem value instead of new)	Rich Felker	2011-03-07	1	-1/+1
\|
*	use the selected clock from the condattr for pthread_cond_timedwait	Rich Felker	2011-03-07	3	-1/+3
\|
*	add prototypes for pthread_condattr_* and pthread_rwlockattr_*	Rich Felker	2011-03-07	1	-0/+12
\|
*	implement pthread_rwlockattr_* (essentially no-ops)	Rich Felker	2011-03-07	4	-0/+28
\|
*	implement pthread_condattr_* interfaces	Rich Felker	2011-03-07	6	-0/+45
\| \| \| \| \|	note that, while the attributes are stored, they are not used in pthread_cond_init yet.
*	reject invalid attribute settings	Rich Felker	2011-03-07	2	-0/+2
\| \| \| \| \|	note that this is a pedantic conformance issue and waste of code. it only affects broken code or code that is probing for conformance.
*	implement barrier attribute functions (essentially no-ops)	Rich Felker	2011-03-07	4	-0/+27
\|

*	implement POSIX shared memory	Rich Felker	2011-03-03	2	-0/+42
\|
*	use -L/...../ -lgcc instead of /...../libgcc.a in musl-gcc wrapper	Rich Felker	2011-03-01	1	-1/+2
\| \| \| \| \| \|	this should avoid warnings about unused libs when not linking, and might fix some other obscure issues too. i might replace this approach with a completely different one soon though.
*	depends on settimeofday which needs _GNU_SOURCE feature test	Rich Felker	2011-03-01	1	-0/+1
\|
*	implement futimens and utimensat	Rich Felker	2011-02-27	3	-0/+16
\|
*	cleanup namespace in sys/time.h	Rich Felker	2011-02-27	1	-4/+5
\|
*	implement fexecve	Rich Felker	2011-02-27	2	-0/+11
\|
*	cleanup utf-8 multibyte code, use visibility if possible	Rich Felker	2011-02-27	3	-84/+5
\| \| \| \| \| \| \| \| \| \| \| \| \|	this code was written independently of musl, with support for a the backwards, nonstandard "31-bit unicode" some libraries/apps might want. unfortunately the extra code (inside #ifdef) makes the source harder to read and makes code that should be simple look complex, so i'm removing it. anyone who wants to use the old code can find it in the history or from elsewhere. also, change the visibility of the __fsmu8 state machine table to hidden, if supported. this should improve performance slightly in shared-library builds.
*	fix missing prototype for strsignal	Rich Felker	2011-02-26	2	-0/+2
\|
*	various changes in preparation for dynamic linking support	Rich Felker	2011-02-24	4	-8/+24
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	prefer using visibility=hidden for __libc internal data, rather than an accessor function, if the compiler has visibility. optimize with -O3 for PIC targets (shared library). without heavy inlining, reloading the GOT register in small functions kills performance. 20-30% size increase for a single libc.so is not a big deal, compared to comparaible size increase in every static binaries. use -Bsymbolic-functions, not -Bsymbolic. global variables are subject to COPY relocations, and thus binding their addresses in the library at link time will cause library functions to read the wrong (original) copies instead of the copies made in the main program's bss section. add entry point, _start, for dynamic linker.
*	apply feature test protection to memccpy	Rich Felker	2011-02-24	1	-1/+4
\|
*	add implementation of memccpy function	Rich Felker	2011-02-24	1	-0/+32
\|
*	fix backwards conditional in stpncpy	Rich Felker	2011-02-24	1	-1/+1
\| \| \| \| \| \|	this only made the function unnecessarily slow on systems with unaligned access, but would of course crash on systems that can't do unaligned accesses (none of which have ports yet).
*	rewind must clear the error indicator in addition to seeking	Rich Felker	2011-02-22	1	-2/+5
\|
*	change errno to static linkage (improves PIC code generation)	Rich Felker	2011-02-21	1	-4/+2
\|
*	cleanup comment cruft in startup code	Rich Felker	2011-02-21	1	-1/+0
\|
*	make startup code PIE-compatible	Rich Felker	2011-02-21	1	-2/+4
\|
*	remove sample utf-8 code that's not part of the standard library	Rich Felker	2011-02-21	1	-47/+0
\|
*	use an accessor function for __libc data pointer when compiled as PIC	Rich Felker	2011-02-20	2	-4/+19
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	prior to this change, a large portion of libc was unusable prior to relocation by the dynamic linker, due to dependence on the global data in the __libc structure and the need to obtain its address through the GOT. with this patch, the accessor function __libc_loc is now able to obtain the address of __libc via PC-relative addressing without using the GOT. this means the majority of libc functionality is now accessible right away. naturally, the above statements all depend on having an architecture where PC-relative addressing and jumps/calls are feasible, and a compiler that generates the appropriate code.
*	avoid referencing address of extern function from vdprintf	Rich Felker	2011-02-20	1	-1/+6
\| \| \| \| \| \| \| \|	this change is in preparation for upcoming PIC/shared library support. the intent is to avoid going through the GOT, mainly so that dprintf is operable immediately, prior to processing of relocations. having dprintf accessible from the dynamic linker will make writing and debugging the dynamic linker much easier.
*	shave off 2 bytes from crt1.o _start	Rich Felker	2011-02-20	1	-2/+2
\|
*	cleanup asprintf stuff	Rich Felker	2011-02-20	2	-2/+2
\|
*	prototypes for GNU asprintf/vasprintf	Rich Felker	2011-02-20	1	-0/+2
\|
*	fix %n specifier, again. this time it was storing the wrong value.	Rich Felker	2011-02-20	1	-7/+7
\|
*	include sys/sysmacros.h from sys/types.h when _GNU_SOURCE is defined	Rich Felker	2011-02-20	1	-0/+1
\|
*	fix typo in inotify structure	Rich Felker	2011-02-20	1	-1/+1
\|
*	make malloc(0) return unique pointers rather than NULL	Rich Felker	2011-02-20	2	-6/+10
\| \| \| \| \| \| \|	this change is made with some reluctance, but i think it's for the best. correct programs must handle either behavior, so there is little advantage to having malloc(0) return NULL. and i managed to actually make the malloc code slightly smaller with this change.
*	fix simple_malloc malloc(0) behavior not to return non-unique pointers	Rich Felker	2011-02-20	1	-0/+1
\|
*	fix simple_malloc size restrictions	Rich Felker	2011-02-20	1	-5/+6
\| \| \| \| \| \|	do not allow allocations that overflow ptrdiff_t; fix some overflow checks that were not quite right but didn't matter due to address layout implementation.
*	fix null pointer dereference introduced in last sigprocmask commit	Rich Felker	2011-02-20	1	-1/+1
\|
*	make real symbols for the legacy (nonstandardized) utmp functions	Rich Felker	2011-02-20	2	-6/+23
\| \| \| \| \| \| \|	this is needed in the long term for ABI compatibility anyway, and in the immediate, it helps with building broken programs like GNU screen that try to prototype the functions themselves rather than using the header.
