| * | fix types for wctype_t and wctrans_t•••wctype_t was incorrectly "int" rather than "long" on x86_64. not only
is this an ABI incompatibility; it's also a major design flaw if we
ever wanted wctype_t to be implemented as a pointer, which would be
necessary if locales support custom character classes, since int is
too small to store a converted pointer. this commit fixes wctype_t to
be unsigned long on all archs, matching the LSB ABI; this change does
not matter for C code, but for C++ it affects mangling.
the same issue applied to wctrans_t. glibc/LSB defines this type as
const __int32_t *, but since no such definition is visible, I've just
expanded the definition, int, everywhere.
it would be nice if these types (which don't vary by arch) could be in
wctype.h, but the OB XSI requirement in POSIX that wchar.h expose some
types and functions from wctype.h precludes doing so. glibc works
around this with some hideous hacks, but trying to duplicate that
would go against the intent of musl's headers.

| * | add missing mmap options and madvices to bits/mman.h based on linux headers | Szabolcs Nagy | 2013-01-12 | 1 | -0/+6 |
| * | add missing F_GETOWNER_UIDS flag to bits/fcntl.h | Szabolcs Nagy | 2013-01-12 | 1 | -0/+2 |
| * | add more arch-specific MAP_ macros to bits/mman.h•••these are also needed by qemu.
| rofl0r | 2012-12-06 | 1 | -0/+4 |
| * | add MAP_NORESERVE to bits/mman.h•••this is needed for qemu, and since it differs for each arch
it can't be circumvented easily by using a macro in CFLAGS.

| * | fixup mcontext stuff to expost gregset_t/fpregset_t as appropriate | Rich Felker | 2012-11-25 | 1 | -1/+19 |
| * | make sys/procfs.h mostly work on most archs•••these structures are purely for use by trace/debug tools and tools
working with core files. the definition of fpregset_t, which was
previously here, has been removed because it was wrong; fpregset_t
should be the type used in mcontext_t, not the type used in
ptrace/core stuff.

| * | begin sys/user.h and sys/reg.h fixes for ports•••aside from microblaze, these should be roughly correct for all archs
now. some misc junk macros and typedefs are missing, which should
probably be added for max compatibility with trace/debug tools.

| * | fix termios constants on mips | Rich Felker | 2012-11-23 | 1 | -10/+21 |
| * | sigcontext/mcontext cleanup for arch-specific bits•••with these changes, the members/types of mcontext_t and related stuff
should closely match the glibc definitions. unlike glibc, however, the
definitions here avoid using typedefs as much as possible and work
directly with the underlying types, to minimize namespace pollution
from signal.h in the default (_BSD_SOURCE) profile.
this is a first step in improving compatibility with applications
which poke at context/register information -- mainly debuggers, trace
utilities, etc. additional definitions in ucontext.h and other headers
may be needed later.
if feature test macros are used to request a conforming namespace,
mcontext_t is replaced with an opaque structure of the equivalent size
and alignment; conforming programs cannot examine its contents anyway.

| * | fix up leftover, incorrect NSIG definitions in arch-specific signal.h | Rich Felker | 2012-11-23 | 1 | -1/+0 |
| * | add back NSIG, removed from powerpc in last commit, but for all archs•••unlike the previous definition, NSIG/_NSIG is supposed to be one more
than the highest signal number. adding this will allow simplifying
libc-internal code that makes signal-related syscalls, which can be
done as a later step. some apps might use it too; while this usage is
questionable, it's at least not insane.
| Rich Felker | 2012-11-21 | 1 | -0/+2 |
| * | fix breakage from introducing bits header for sys/io.h•••apparently some other archs have sys/io.h and should not break just
because they don't have the x86 port io functions. provide a blank
bits/io.h everywhere for now.
| Rich Felker | 2012-11-18 | 1 | -0/+0 |
| * | fcntl.h: O_SEARCH was missing for powerpc•••put some macros that do not differ between architectures in the
main header and remove from bits.
restructure mips header so it has the same structure as the others.
| rofl0r | 2012-11-18 | 1 | -12/+9 |
| * | disable SO_REUSEPORT in sys/socket.h•••although a number is reserved for it, this option is not implemented
on Linux and does not work. defining it causes some applications to
use it, and subsequently break due to its failure.
| Rich Felker | 2012-11-15 | 1 | -1/+1 |
| * | fix numerous mips abi constant definition mismatches | Rich Felker | 2012-11-05 | 3 | -89/+120 |
| * | better support for reverse-endian variants of arm/mips/microblaze•••these macros are supported by more compilers
| Rich Felker | 2012-10-18 | 1 | -0/+4 |
| * | floating point environment/exceptions support for mips | Rich Felker | 2012-10-18 | 1 | -3/+13 |
| * | fix broken semctl on systems that don't use IPC_64 flag•••not tested on mips and arm; they may still be broken. x86_64 should be
ok now.
| Rich Felker | 2012-09-22 | 1 | -0/+2 |
| * | add O_EXEC open mode•••the linux O_PATH mode provides the necessary semantics for both the
O_SEARCH and O_EXEC modes defined and required by POSIX 2008.
| Rich Felker | 2012-09-15 | 1 | -0/+1 |
| * | add O_PATH/O_SEARCH support to fcntl.h•••I'm not 100% sure that Linux's O_PATH meets the POSIX requirements for
O_SEARCH, but it seems very close if not perfect. and old kernels
ignore it, so O_SEARCH will still work as desired as long as the
caller has read permissions to the directory.
| Rich Felker | 2012-09-13 | 1 | -0/+2 |
| * | syscall organization overhaul•••now public syscall.h only exposes __NR_* and SYS_* constants and the
variadic syscall function. no macros or inline functions, no
__syscall_ret or other internal details, no 16-/32-bit legacy syscall
renaming, etc. this logic has all been moved to src/internal/syscall.h
with the arch-specific parts in arch/$(ARCH)/syscall_arch.h, and the
amount of arch-specific stuff has been reduced to a minimum.
changes still need to be reviewed/double-checked. minimal testing on
i386 and mips has already been performed.

| * | 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.

| * | fix incorrect ptrdiff_t type on mips | Rich Felker | 2012-08-10 | 1 | -1/+1 |
| * | add defines for number of sigset_t bytes syscalls expect•••yet another gratuitous mips incompatibility...
| Rich Felker | 2012-08-09 | 1 | -0/+2 |
| * | further fixes for mips ioctl.h header•••untested; hopefully it's right now
| Rich Felker | 2012-08-07 | 1 | -4/+4 |
| * | fix another mips gratuitous-incompatibility bug: ioctl numbers | Rich Felker | 2012-08-07 | 1 | -2/+2 |
| * | fix socket.h on mips•••why does mips have to be gratuitously incompatible in every possible
imaginable way?
| Rich Felker | 2012-08-05 | 1 | -0/+3 |
| * | add floating point register saving/restoring to mips setjmp/longjmp•••also fix the alignment of jmp_buf to meet the abi. linux always
emulates fpu on mips if it's not present, so enabling this code
unconditionally is "safe" but may be slow. in the long term it may be
preferable to find a way to disable it on soft float builds.
| Rich Felker | 2012-07-22 | 1 | -1/+1 |
| * | workaround another sendmsg kernel bug on 64-bit machines•••the kernel wrongly expects the cmsg length field to be size_t instead
of socklen_t. in order to work around the issue, we have to impose a
length limit and copy to a local buffer. the length limit should be
more than sufficient for any real-world use; these headers are only
used for passing file descriptors and permissions between processes
over unix sockets.
| Rich Felker | 2012-07-12 | 1 | -0/+7 |
| * | fix redef of sigprocmask constants on mips•••this fix is easier than trying to reorder the header stuff
| Rich Felker | 2012-07-12 | 1 | -0/+3 |
| * | more mips bits-header fixes•••signal handling was very broken because of this
| Rich Felker | 2012-07-12 | 1 | -2/+6 |
| * | fix mips syscalls with long long args•••like arm, mips requires 64-bit arguments to be "aligned" on an even
register boundary.
| Rich Felker | 2012-07-12 | 1 | -1/+1 |
| * | fix mips mcontext_t structure size•••otherwise offs in ucontext_t will be wrong, and break code that
inspects or modifies the signal makes (including cancellation code).
| Rich Felker | 2012-07-12 | 1 | -1/+5 |
| * | fix MAP_ANONYMOUS value for mips, remove cruft copied from i386 | Rich Felker | 2012-07-11 | 1 | -2/+1 |
| * | initial version of mips (o32) port, based on work by Richard Pennington (rdp)•••basically, this version of the code was obtained by starting with
rdp's work from his ellcc source tree, adapting it to musl's build
system and coding style, auditing the bits headers for discrepencies
with kernel definitions or glibc/LSB ABI or large file issues, fixing
up incompatibility with the old binutils from aboriginal linux, and
adding some new special cases to deal with the oddities of sigaction
and pipe syscall interfaces on mips.
at present, minimal test programs work, but some interfaces are broken
or missing. threaded programs probably will not link.
