* fix type issues in stdint.h so underlying types of 64-bit types match ABIRich Felker2013-04-046-0/+18
|
* eliminate bits/wchar.hRich Felker2013-04-046-24/+0
| | | | | | | 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.
* re-add useconds_trofl0r2013-04-026-0/+6
| | | | | | | | 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.
* add syscall numbers for the new kcmp and finit_module syscallsSzabolcs Nagy2013-04-016-9/+46
| | | | and remove syscall todos from microblaze
* add the new SO_REUSEPORT socket option to mips and powerpcSzabolcs Nagy2013-04-012-1/+2
| | | | | SO_REUSEPORT implementation was merged in the linux kernel commit c617f398edd4db2b8567a28e899a88f8f574798d 2013-01-23
* remove __SYSCALL_SSLEN arch macro in favor of using public _NSIGRich Felker2013-03-266-12/+0
| | | | | | | | | | | | | | 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.
* add deprecated SIGIOT alias for SIGABRTRich Felker2013-03-235-1/+5
| | | | reportedly some programs (e.g. showkeys in the kbd package) use it.
* fix types for wctype_t and wctrans_tRich Felker2013-03-046-12/+12
| | | | | | | | | | | | | | | | | | | | 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_64Rich Felker2013-02-261-1/+1
| | | | x86_64 does not have excess precision, at all
* arm: add __aeabi_atexit()rofl0r2013-02-061-0/+6
| | | | | | | | | | | | | | | | | | | 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.
* 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.hSzabolcs Nagy2013-01-124-0/+4
| | | | mips and powerpc already had this termios flag defined
* add missing F_GETOWNER_UIDS flag to bits/fcntl.hSzabolcs Nagy2013-01-126-0/+11
|
* add missing EHWPOISON to bits/errno.hSzabolcs Nagy2013-01-125-0/+5
| | | | it was already defined for mips, but was missing from other archs
* 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 protectionRich Felker2012-12-062-44/+48
| | | | | | | | 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.
* bits/signal.h: add register names for x86(_64)rofl0r2012-12-062-0/+46
| | | | | | 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.
* add more arch-specific MAP_ macros to bits/mman.hrofl0r2012-12-066-0/+24
| | | | these are also needed by qemu.
* remove MAP_32 from non-x86 archsrofl0r2012-12-063-3/+0
| | | | both kernel and glibc define it only on x86(_64).
* add MAP_NORESERVE to bits/mman.hrofl0r2012-12-066-0/+6
| | | | | this is needed for qemu, and since it differs for each arch it can't be circumvented easily by using a macro in CFLAGS.
* 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.hRich Felker2012-11-261-6/+0
| | | | | if these are to be supported, they belong in the main stat.h, not repeated for each arch.
* fixup mcontext stuff to expost gregset_t/fpregset_t as appropriateRich Felker2012-11-256-10/+32
|
* make sys/procfs.h mostly work on most archsRich Felker2012-11-255-8/+30
| | | | | | | | 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.
* remove microblaze user.h incorrectly copied from armRich Felker2012-11-251-40/+1
|
* begin sys/user.h and sys/reg.h fixes for portsRich Felker2012-11-234-98/+78
| | | | | | 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 powerpc ucontext, again..Rich Felker2012-11-231-5/+0
| | | | | | | | 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.
* fix termios constants on mipsRich Felker2012-11-231-10/+21
|
* sigcontext/mcontext cleanup for arch-specific bitsRich Felker2012-11-235-81/+94
| | | | | | | | | | | | | | | | | 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 powerpc setjmp/longjmp to save/restore float regs; enlarge/align jmp_bufRich Felker2012-11-231-1/+1
|
* 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 sigcontextRich Felker2012-11-231-4/+0
| | | | these fields were wrongly copied from the kernel's ppc64 struct def
* 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 archsRich Felker2012-11-216-0/+12
| | | | | | | | 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.
* make powerpc signal.h namespace-clean for posix/isocRich Felker2012-11-211-19/+32
| | | | | | | | | | 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.
* 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.hRich Felker2012-11-186-6/+0
| | | | | | 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.
* add port io functions to sys/io.hRich Felker2012-11-182-0/+160
| | | | | | | 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, untestedRich Felker2012-11-181-7/+28
| | | | based on code sent to the mailing list by nsz, with minor changes.
* fcntl.h: O_SEARCH was missing for powerpcrofl0r2012-11-185-24/+9
| | | | | | 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.
* ppc socket.h: add forgotten cmsghdrrofl0r2012-11-181-0/+7
|
* dynamic linking support for powerpcRich Felker2012-11-161-8/+27
| | | | | | | | incomplete but at least partly working. requires all files to be compiled in the new "secure" plt model, not the old one that put plt code in the data segment. TLS is untested but may work. invoking the dynamic linker explicitly to load a program does not yet handle argv correctly.
* fix ppc stat structure definitionRich Felker2012-11-161-4/+3
|
* fix powerpc termios.h and ioctl.hrofl0r2012-11-162-192/+232
|
* disable SO_REUSEPORT in sys/socket.hRich Felker2012-11-151-1/+1
| | | | | | 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.
