| * | 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.

| * | | 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...

| * | | 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.

| * | | 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.

| * | | add bsd fgetln function•••optimized to avoid allocation and return lines directly out of the
stream buffer whenever possible.
| Rich Felker | 2012-08-11 | 4 | -1/+25 |
| * | | 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 | 2012-08-10 | 1 | -4/+2 |
| * | | 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 | 2012-08-10 | 1 | -1/+1 |
| * | | 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.

| * | | fix incorrect ptrdiff_t type on mips | Rich Felker | 2012-08-10 | 1 | -1/+1 |
| * | | add blowfish hash support to crypt•••there are still some discussions going on about tweaking the code, but
at least thing brings us to the point of having something working in
the repository. hopefully the remaining major hashes (md5,sha) will
follow soon.
| Rich Felker | 2012-08-10 | 3 | -8/+806 |
| * | | fix (hopefully) all hard-coded 8's for kernel sigset_t size•••some minor changes to how hard-coded sets for thread-related purposes
are handled were also needed, since the old object sizes were not
necessarily sufficient. things have gotten a bit ugly in this area,
and i think a cleanup is in order at some point, but for now the goal
is just to get the code working on all supported archs including mips,
which was badly broken by linux rejecting syscalls with the wrong
sigset_t size.
| Rich Felker | 2012-08-09 | 14 | -20/+31 |
| * | | add defines for number of sigset_t bytes syscalls expect•••yet another gratuitous mips incompatibility...
| Rich Felker | 2012-08-09 | 4 | -0/+8 |
| * | | make crypt return an unmatchable hash rather than NULL on failure•••unfortunately, a large portion of programs which call crypt are not
prepared for its failure and do not check that the return value is
non-null before using it. thus, always "succeeding" but giving an
unmatchable hash is reportedly a better behavior than failing on
error.
it was suggested that we could do this the same way as other
implementations and put the null-to-unmatchable translation in the
wrapper rather than the individual crypt modules like crypt_des, but
when i tried to do it, i found it was making the logic in __crypt_r
for keeping track of which hash type we're working with and whether it
succeeded or failed much more complex, and potentially error-prone.
the way i'm doing it now seems to have essentially zero cost, anyway.

| * | fix socket.h on mips•••why does mips have to be gratuitously incompatible in every possible
imaginable way?
| Rich Felker | 2012-08-05 | 2 | -0/+6 |
| * | align mips _init/_fini functions•••since .init and .fini are not .text, the toolchain does not seem to
align them for code by default. this yields random breakage depending
on the object sizes the linker is dealing with.

| * | remove configure check disabling shared libraries on mips | Rich Felker | 2012-08-05 | 1 | -4/+0 |
| * | mips dynamic linker support•••not heavily tested, but the basics are working. the basic concept is
that the dynamic linker entry point code invokes a pure-PIC (no global
accesses) C function in reloc.h to perform the early GOT relocations
needed to make the dynamic linker itself functional, then invokes
__dynlink like on other archs. since mips uses some ugly arch-specific
hacks to optimize relocating the GOT (rather than just using the
normal DT_REL[A] tables like on other archs), the dynamic linker has
been modified slightly to support calling arch-specific relocation
code in reloc.h.
most of the actual mips-specific behavior was developed by reading the
output of readelf on libc.so and simple executable files. i could not
find good reference information on which relocation types need to be
supported or their semantics, so it's possible that some legitimate
usage cases will not work yet.
| Rich Felker | 2012-08-05 | 3 | -3/+102 |
| * | make dynlink.lo depend on reloc.h in makefile•••this is mainly a development convenience but will also ensure users
building from latest git always get up-to-date arch-specific dynamic
linker code without having to "make clean".

| * | more cleanup of dynamic linker internals | Rich Felker | 2012-08-05 | 1 | -8/+9 |
| * | more dynamic linker internals cleanup•••changing the string printed for the dso name is not a regression; the
old code was simply using the wrong dso name (head rather than the dso
currently being relocated). this will be fixed in a later commit.
| Rich Felker | 2012-08-05 | 1 | -6/+6 |
| * | dynamic linker internals cleanup | Rich Felker | 2012-08-05 | 1 | -5/+7 |
| * | floating point support for arm setjmp/longjmp•••not heavily tested, but at least they don't seem to break anything on
soft float targets with or without coprocessors. they check the auxv
AT_HWCAP flags to determine which coprocessor, if any, is available.
| Rich Felker | 2012-08-05 | 2 | -2/+54 |
| * | release notes for 0.9.3 | Rich Felker | 2012-08-02 | 1 | -0/+35 |
| * | abstract out compiler runtime library for linking libc.so•••this allows config.mak to override the default -lgcc for building with
other compilers such as pcc/clang/etc.
| Rich Felker | 2012-08-02 | 1 | -1/+2 |
| * | fix argument type error on wcwidth function•••since the correct declaration was not visible, and since the
representation of the types wchar_t and wint_t always match, a
compiler would have to go out of its way to make this bug manifest,
but better to fix it anyway.
| Rich Felker | 2012-08-02 | 1 | -2/+2 |
| * | fix missing static in getusershell (namespace pollution) | Rich Felker | 2012-08-02 | 1 | -1/+1 |
| * | optimize mempcpy to minimize need for data saved across the call | Rich Felker | 2012-07-31 | 1 | -2/+1 |
| * | optimize arm setjmp/longjmp register saving/loading•••the original code was wrongly based on how it would be done in thumb
mode, but that's not needed because musl's asm only targets arm.
| Rich Felker | 2012-07-27 | 2 | -6/+2 |
| * | save AT_HWCAP from auxv for subsequent use in machine-specific code•••it's expected that this will be needed/useful only in asm, so I've
given it its own symbol that can be addressed in pc-relative ways from
asm rather than adding a field in the __libc structure which would
require hard-coding the offset wherever it's used.
| Rich Felker | 2012-07-27 | 3 | -0/+4 |
| * | retry on cas failures in sem_trywait•••this seems counter-intuitive since sem_trywait is supposed to just try
once, not wait for the semaphore. however, the retry loop is not a
wait. instead, it's to handle the case where the value changes due to
a simultaneous post or wait from another thread while the semaphore
value remains positive. in such a case, it's absolutely wrong for
sem_trywait to fail with EAGAIN because the semaphore is not busy.
| Rich Felker | 2012-07-24 | 1 | -2/+2 |
| * | gcc wrapper improvement: leave libgcc dir in the library path•••this is needed in case -lgcc is passed explicitly on the link command
line, for example if the wrapper is being used to build musl itself.
