Rich Felker	71df8b2760	use -L/...../ -lgcc instead of /...../libgcc.a in musl-gcc wrapper 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.	15 years ago

Rich Felker	015d33c507	cleanup utf-8 multibyte code, use visibility if possible 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.	15 years ago
Rich Felker	2a195dd31c	fix missing prototype for strsignal	15 years ago
Rich Felker	41d518360f	various changes in preparation for dynamic linking support 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.	15 years ago

Rich Felker	b8ff2aaabb	add implementation of memccpy function	15 years ago
Rich Felker	9f19b3ec8d	fix backwards conditional in stpncpy 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).	15 years ago

Rich Felker	cfcbea1e43	remove sample utf-8 code that's not part of the standard library	15 years ago
Rich Felker	d89c9e8a63	use an accessor function for __libc data pointer when compiled as PIC 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.	15 years ago
Rich Felker	4ee039f354	avoid referencing address of extern function from vdprintf 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.	15 years ago

Rich Felker	f552c792c7	include sys/sysmacros.h from sys/types.h when _GNU_SOURCE is defined	15 years ago
Rich Felker	b1b752372f	fix typo in inotify structure	15 years ago
Rich Felker	26031da0f8	make malloc(0) return unique pointers rather than NULL 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.	15 years ago
Rich Felker	598a0147cd	fix simple_malloc malloc(0) behavior not to return non-unique pointers	15 years ago
Rich Felker	a23baf586a	fix simple_malloc size restrictions 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.	15 years ago
Rich Felker	96f2197494	fix null pointer dereference introduced in last sigprocmask commit	15 years ago
Rich Felker	eee150f39c	make real symbols for the legacy (nonstandardized) utmp functions 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.	15 years ago
Rich Felker	d6a1e0c79e	resolve some header namespace non-issues after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection.	15 years ago
Rich Felker	855df698c4	move the GNU siginfo renaming so it doesn't lead to mismatching names	15 years ago
Rich Felker	8668f033bc	fill in some missing siginfo stuff in signal.h	15 years ago
Rich Felker	2b43ef8fc7	make sys/param.h not depend on PATH_MAX and NAME_MAX this is a nonstandard header used only by backwards programs, but for some reason it's extremely popular. the recent namespace cleanup fixes broke it, because PATH_MAX and NAME_MAX will not be defined unless an approriate feature test macro has been defined. moreover, it's too late to just #define _GNU_SOURCE in param.h, since limits.h may have already been included. let's just hard-code standard values and be done with it.	15 years ago
Rich Felker	13e8459232	workaround gcc bug 46926 by providing a dumb sincos implementation note that this library itself is built with -ffreestanding so sincos.c should not be miscompiled even if the gcc used to compile musl has this bug.	15 years ago
Rich Felker	98e02144da	use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit code	15 years ago
Rich Felker	5316d083ec	fix typo in wordexp.h (note that the function is still unimplemented)	15 years ago
Rich Felker	4b1244a0bf	implement the remaining clock_* interfaces	15 years ago
Rich Felker	19eb13b9a4	race condition fix: block all signals before decrementing thread count the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals.	15 years ago
Rich Felker	a49c119276	prevent sigprocmask/pthread_sigmask from blocking implementation signals this code was wrongly disabled because the old version was trying to be too clever and didn't work. replaced it with a simple version for now.	15 years ago
Rich Felker	fb11b6b85e	make pthread_exit run dtors for last thread, wait to decrement thread count	15 years ago
Rich Felker	69ecbd0f31	make mktemp match the historic behavior, and update functions that use it the historic mktemp is supposed to blank the template string on failure, rather than returning 0. just zero the first character so that mkstemp and mkdtemp can still retry with O(1) space requirement.	15 years ago
Rich Felker	2e6239dd06	fix major bug created from copying mkdtemp logic	15 years ago
Rich Felker	095a5ae6f2	add syscall wrappers for inotify	15 years ago
