| 2012-09-06 | remove dependency of wmemmove on wmemcpy direction•••unlike the memmove commit, this one should be fine to leave in place.
wmemmove is not performance-critical, and even if it were, it's
already copying whole 32-bit words at a time instead of bytes.

| 2012-09-06 | remove dependency of memmove on memcpy direction•••this commit introduces a performance regression in many uses of
memmove, which will need to be addressed before the next release. i'm
making it as a temporary measure so that the restrict patch can be
committed without invoking undefined behavior when memmove calls
memcpy with overlapping regions.

| 2012-09-06 | fix broken ttyname[_r] (failure to null-terminate result) | Rich Felker | 1 | -1/+4 |
| 2012-09-02 | avoid "inline" in public headers for strict c89 compatibility•••while musl itself requires a c99 compiler, some applications insist on
being compiled with c89 compilers, and use of "inline" in the headers
was breaking them. much of this had been avoided already by just
skipping the inline keyword in pre-c99 compilers or modes, but this
new unified solution is cleaner and may/should result in better code
generation in the default gcc configuration.

| 2012-09-01 | fix wrong type for poll.h nfds_t•••this should not break anything since the type should never be used
except as the argument type for poll.

| 2012-08-30 | fix missing statics in crypt_sha256 code | Rich Felker | 1 | -3/+3 |
| 2012-08-29 | anti-DoS rounds count limits for blowfish and des crypt•••all of the limits could use review, but err on the side of avoiding
excessive rounds for now.
| Rich Felker | 2 | -2/+2 |
| 2012-08-29 | limit sha512 rounds to similar runtime to sha256 limit•••these limits could definitely use review, but for now, i feel
consistency and erring on the side of preventing servers from getting
bogged down by excessively-slow user-provided settings (think
.htpasswd) are the best policy. blowfish should be updated to match.
| Rich Felker | 1 | -1/+1 |
| 2012-08-29 | add sha256/sha512 crypt•••based on versions sent to the list by nsz, with some simplification
and debloating. i'd still like to get them a bit smaller, or ideally
merge them into a single file with most of the code being shared, but
that can be done later.

| 2012-08-29 | get rid of eh_frame bloat•••if needed for debugging, it will be output in the .debug_frame section
instead, where it is not part of the loaded program and where the
strip command is free to strip it.

| 2012-08-27 | fix bug caused by main app & libc having map set; cannot free them | Rich Felker | 1 | -1/+1 |
| 2012-08-26 | dladdr support for dynamic linker (nonstandard extension)•••based on patches submitted by boris brezillon. this commit also fixes
the issue whereby the main application and libc don't have the address
ranges of their mappings stored, which was theoretically a problem for
RTLD_NEXT support in dlsym; it didn't actually matter because libc
never calls dlsym, and it seemed to be doing the right thing (by
chance) for symbols in the main program as well.

| 2012-08-25 | implement "low hanging fruit" from C11•••based on Gregor's patch sent to the list. includes:
- stdalign.h
- removing gets in C11 mode
- adding aligned_alloc and adjusting other functions to use it
- adding 'x' flag to fopen for exclusive mode
| Rich Felker | 7 | -49/+75 |
| 2012-08-25 | add c11 quick_exit and at_quick_exit functions | Rich Felker | 3 | -0/+46 |
| 2012-08-25 | fix bug in gnu hash lookup on dlsym(handle, name) lookups•••wrong hash was being passed; just a copy/paste error. did not affect
lookups in the global namespace; this is probably why it was not
caught in testing.

| 2012-08-25 | clean up search_vec usage for vdso | Rich Felker | 1 | -2/+2 |
| 2012-08-25 | use new search_vec function to find vdso in dynamic linker | Rich Felker | 1 | -4/+2 |
| 2012-08-25 | ensure canary is setup if stack-prot libs are dlopen'd into non-ssp app•••previously, this usage could lead to a crash if the thread pointer was
still uninitialized, and otherwise would just cause the canary to be
zero (less secure).

| 2012-08-25 | add gnu hash support in the dynamic linker•••based on the patches contributed by boris brezillon.

| 2012-08-19 | fix bug whereby most atexit-registered functions got skipped | Rich Felker | 1 | -3/+2 |
| 2012-08-18 | make dynamic linker report all failures before exiting•••before, only the first library that failed to load or symbol that
failed to resolve was reported, and then the dynamic linker
immediately exited. when attempting to fix a library compatibility
issue, this is about the worst possible behavior. now we print all
errors as they occur and exit at the very end if errors were
encountered.

| 2012-08-17 | release notes for 0.9.4 | Rich Felker | 1 | -0/+29 |
| 2012-08-17 | add mips to supported arch list in INSTALL file | Rich Felker | 1 | -1/+1 |
| 2012-08-17 | crt1 must align stack pointer on mips•••it's naturally aligned when entered with the kernel argv array, but if
ld.so has been invoked explicitly to run a program, the stack will not
be aligned due to having thrown away argv[0].

| Rich Felker | 1 | -2/+10 |
| 2012-08-17 | fix extremely rare but dangerous race condition in robust mutexes•••if new shared mappings of files/devices/shared memory can be made
between the time a robust mutex is unlocked and its subsequent removal
from the pending slot in the robustlist header, the kernel can
inadvertently corrupt data in the newly-mapped pages when the process
terminates. i am fixing the bug by using the same global vm lock
mechanism that was used to fix the race condition with unmapping
barriers after pthread_barrier_wait returns.
| Rich Felker | 3 | -20/+33 |
| 2012-08-17 | fix float parsing logic for long decimal expansions•••this affects at least the case of very long inputs, but may also
affect shorter inputs that become long due to growth while upscaling.
basically, the logic for the circular buffer indices of the initial
base-10^9 digit and the slot one past the final digit, and for
simplicity of the loop logic, assumes an invariant that they're not
equal. the upscale loop, which can increase the length of the
base-10^9 representation, attempted to preserve this invariant, but
was actually only ensuring that the end index did not loop around past
the start index, not that the two never become equal.
the main (only?) effect of this bug was that subsequent logic treats
the excessively long number as having no digits, leading to junk
results.

| 2012-08-15 | handle null arguments to legacy bsd err.h functions | Rich Felker | 1 | -2/+2 |
| 2012-08-15 | improve headers to better deal with removed-in-posix-2008 features•••with this patch, setting _POSIX_SOURCE, or setting _POSIX_C_SOURCE or
_XOPEN_SOURCE to an old version, will bring back the interfaces that
were removed in POSIX 2008 - at least the ones i've covered so far,
which are gethostby*, usleep, and ualarm. if there are other functions
still in widespread use that were removed for which similar changes
would be beneficial, they can be added just like this.
| Rich Felker | 2 | -13/+22 |
| 2012-08-15 | add missing xattr functions•••not sure why these were originally omitted..
| Rich Felker | 2 | -0/+18 |
| 2012-08-15 | update copyright/credits for recent code additions | Rich Felker | 1 | -2/+12 |
| 2012-08-14 | support configuring cross compiling with CROSS_COMPILE prefix variable | Rich Felker | 1 | -3/+6 |
| 2012-08-13 | math: fix _BSD_SOURCE namespace in math.h | nsz | 1 | -25/+26 |
| 2012-08-13 | remove significandl•••this function never existed historically; since the float/double
functions it's based on are nonstandard and deprecated, there's really
no justification for its existence except that glibc has it. it can be
added back if there's ever really a need...
| Rich Felker | 2 | -8/+0 |
| 2012-08-13 | add significand[fl] math functions | Rich Felker | 4 | -0/+25 |
| 2012-08-13 | publicly expose getdents api under _BSD_SOURCE | Rich Felker | 1 | -0/+7 |
| 2012-08-11 | memcpy asm for i386 and x86_64 | Rich Felker | 2 | -0/+51 |
| 2012-08-11 | avoid need for -march=mips2 to compile mips atomic.h asm•••linux guarantees ll/sc are always available. on mips1, they will be
emulated by the kernel. thus they are part of the linux mips1 abi and
safe to use.
| Rich Felker | 1 | -0/+8 |
| 2012-08-11 | remove unused but buggy code from strstr.c | Rich Felker | 1 | -10/+0 |
| 2012-08-11 | remove buggy short-string wcsstr implementation; always use twoway•••since this interface is rarely used, it's probably best to lean
towards keeping code size down anyway. one-character needles will
still be found immediately by the initial wcschr call anyway.
| Rich Felker | 1 | -9/+0 |
| 2012-08-11 | add bsd fgetln function•••optimized to avoid allocation and return lines directly out of the
stream buffer whenever possible.
| Rich Felker | 4 | -1/+25 |
| 2012-08-10 | minor but worthwhile optimization in printf: avoid expensive strspn•••the strspn call was made for every format specifier and end-of-string,
even though the expected return value was 1-2 for normal usage.
replace with simple loop.
| Rich Felker | 1 | -4/+2 |
| 2012-08-10 | trivial optimization to printf: avoid wasted call frame•••amusingly, this cuts more than 10% off the run time of printf("a"); on
the machine i tested it on.
sadly the same optimization is not possible for snprintf without
duplicating all the pseudo-FILE setup code, which is not worth it.
| Rich Felker | 1 | -1/+1 |
| 2012-08-10 | use int instead of long for ptrdiff_t on all 32-bit archs•••this is needed to match the underlying "ABI" standards. it's not
really an ABI issue since the binary representations are the same, but
having the wrong type can lead to errors when the type arising from a
difference-of-pointers expression does not match the defined type of
ptrdiff_t. most of the problems affect C++, not C.
