* respect iso c namespace in stdio.h and wchar.h regarding va_list•••despite declaring functions that take arguments of type va_list, these headers are not permitted by the c standard to expose the definition of va_list, so an alias for the type must be used. the name __isoc_va_list was chosen to convey that the purpose of this alternate name is for iso c conformance, and to avoid the multitude of names which gcc mangles with its hideous "fixincludes" monstrosity, leading to serious header breakage if these "fixes" are run.

| * fix ioctl _IOR, _IOW, etc macros to avoid signed overflow (2<<30)Szabolcs Nagy2013-05-266-38/+19
| * on x86_64 use long instead of long long for 64bit posix types•••following glibc use the lowest rank 64bit integer type for ino_t etc. this is eg. useful for printf format compatibility Szabolcs Nagy2013-05-261-4/+4
* | change underlying type of clock_t to be uniform and match ABI•••previously we were using an unsigned type on 32-bit systems so that subtraction would be well-defined when it wrapped, but since wrapping is non-conforming anyway (when clock() overflows, it has to return -1) the only use of unsigned would be to buy a little bit more time before overflow. this does not seem worth having the type vary per-arch (which leads to more arch-specific bugs) or disagree with the ABI musl (mostly) follows.

* add FLT_TRUE_MIN, etc. macros from C11•••there was some question as to how many decimal places to use, since one decimal place is always sufficient to identify the smallest denormal uniquely. for now, I'm following the example in the C standard which is consistent with the other min/max macros we already had in place. Rich Felker2013-05-176-0/+6
* fix type issues in stdint.h so underlying types of 64-bit types match ABIRich Felker2013-04-046-0/+18
* eliminate bits/wchar.h•••the preprocessor can reliably determine the signedness of wchar_t. L'\0' is used for 0 in the expressions so that, if the underlying type of wchar_t is long rather than int, the promoted type of the expression will match the type of wchar_t. Rich Felker2013-04-046-24/+0
* re-add useconds_t•••this type was removed back in 5243e5f1606a9c6fcf01414e , because it was removed from the XSI specs. however some apps use it. since it's in the POSIX reserved namespace, we can expose it unconditionally. rofl0r2013-04-026-0/+6
* add syscall numbers for the new kcmp and finit_module syscalls•••and remove syscall todos from microblaze Szabolcs Nagy2013-04-016-9/+46
* add the new SO_REUSEPORT socket option to mips and powerpc•••SO_REUSEPORT implementation was merged in the linux kernel commit c617f398edd4db2b8567a28e899a88f8f574798d 2013-01-23 Szabolcs Nagy2013-04-012-1/+2
* remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG•••the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part. Rich Felker2013-03-266-12/+0
* add deprecated SIGIOT alias for SIGABRT•••reportedly some programs (e.g. showkeys in the kbd package) use it. Rich Felker2013-03-235-1/+5
* 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.

* fix wrong float_t on x86_64•••x86_64 does not have excess precision, at all Rich Felker2013-02-261-1/+1
* arm: add __aeabi_atexit()•••arm eabi requires this symbol for static C++ dtors. usually it is provided by libstdc++, but when a C++ program doesn't use the std lib (free-standing), the libc has to provide it. this was encountered while building transmission, which depends on such a C++ library (libutp). this function is nearly identical to __cxa_atexit, but it has the order of argumens swapped for "performance reasons". see page 25 of http://infocenter.arm.com/help/topic/com.arm.doc.ihi0043d/IHI0043D_rtabi.pdf there are other aeabi specific C++ support functions missing, but it is not clear yet that GCC makes use of them so we omit them for the moment. rofl0r2013-02-061-0/+6
* add missing mmap options and madvices to bits/mman.h based on linux headersSzabolcs Nagy2013-01-126-0/+41
* add missing EXTPROC flag to bits/termios.h•••mips and powerpc already had this termios flag defined Szabolcs Nagy2013-01-124-0/+4
* add missing F_GETOWNER_UIDS flag to bits/fcntl.hSzabolcs Nagy2013-01-126-0/+11
* add missing EHWPOISON to bits/errno.h•••it was already defined for mips, but was missing from other archs Szabolcs Nagy2013-01-125-0/+5
* x86_64/bits/signal.h: fix typo in REG_CSGSFSrofl0r2012-12-191-1/+1
* fix trailing whitespace issues that crept in here and thereRich Felker2012-12-071-9/+9
* move signal.h REG_* macros under _GNU_SOURCE protection•••they were accidentally exposed under just baseline POSIX, which is a big namespace pollution issue. thankfully glibc only exposes them under _GNU_SOURCE, not under any of its other options, so omitting the pollution in the default _BSD_SOURCE profile does not hurt application compatibility at all. Rich Felker2012-12-062-44/+48
* bits/signal.h: add register names for x86(_64)•••glibc exposes them from ucontext.h. since that header includes signal.h, it is safe to put them into bits/signal.h, if _GNU_SOURCE is defined. rofl0r2012-12-062-0/+46
* add more arch-specific MAP_ macros to bits/mman.h•••these are also needed by qemu. rofl0r2012-12-066-0/+24
* remove MAP_32 from non-x86 archs•••both kernel and glibc define it only on x86(_64). rofl0r2012-12-063-3/+0
* 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. rofl0r2012-12-066-0/+6
* fix regression in arm user.h that happened during big user.h changesRich Felker2012-12-041-0/+1
* remove stat member aliases from ppc-specific bits/stat.h•••if these are to be supported, they belong in the main stat.h, not repeated for each arch. Rich Felker2012-11-261-6/+0
* fixup mcontext stuff to expost gregset_t/fpregset_t as appropriateRich Felker2012-11-256-10/+32
* 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. Rich Felker2012-11-255-8/+30
* remove microblaze user.h incorrectly copied from armRich Felker2012-11-251-40/+1
* 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. Rich Felker2012-11-234-98/+78
* fix powerpc ucontext, again..•••it should now really match the kernel. some of the removed padding corresponded to the difference between user and kernel sigset_t. the space at the end was redundant with the uc_mcontext member and seems to have been added as a result of misunderstanding glibc's definition versus the kernel's. Rich Felker2012-11-231-5/+0
* fix termios constants on mipsRich Felker2012-11-231-10/+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.hRich Felker2012-11-235-5/+0
* remove stuff that doesn't belong in powerpc 32-bit sigcontext•••these fields were wrongly copied from the kernel's ppc64 struct def Rich Felker2012-11-231-4/+0
* more ppc signal.h typedef order fixesRich Felker2012-11-211-13/+13
* fix misordered typedefs in ppc signal.hRich Felker2012-11-211-2/+2
* ppc signal/NSIG related fix (warning fix, redefinition)Rich Felker2012-11-211-2/+1
* 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 Felker2012-11-216-0/+12
* make powerpc signal.h namespace-clean for posix/isoc•••also handle the non-GNUC case where alignment attribute is not available by simply omitting it. this will not cause problems except for inclusion of mcontex_t/ucontext_t in application-defined structures, since the natural alignment of the uc_mcontext member relative to the start of ucontext_t is already correct. and shame on whoever designed this for making it impossible to satisfy the ABI requirements without GNUC extensions. Rich Felker2012-11-211-19/+32
* fix powerpc types to match abi, and some feature test issuesRich Felker2012-11-213-7/+8
* fix invalid usage of mcontext_t in powerpc signal.hrofl0r2012-11-211-1/+1
* 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 Felker2012-11-186-6/+0
* add port io functions to sys/io.h•••based on proposal by Isaac Dunham. nonexistance of bits/io.h will cause inclusion of sys/io.h to produce an error on archs that are not supposed to have it. this is probably the desired behavior, but the error message may be a bit unusual.

* add missing const on powerpc FE_DFL_ENVRich Felker2012-11-181-1/+1
* fenv support for ppc, untested•••based on code sent to the mailing list by nsz, with minor changes. Rich Felker2012-11-181-7/+28
