2013-01-12add missing mmap options and madvices to bits/mman.h based on linux headersSzabolcs Nagy6-0/+41
2013-01-12add missing EXTPROC flag to bits/termios.hSzabolcs Nagy4-0/+4
mips and powerpc already had this termios flag defined
2013-01-12add missing F_GETOWNER_UIDS flag to bits/fcntl.hSzabolcs Nagy6-0/+11
2013-01-12add missing EHWPOISON to bits/errno.hSzabolcs Nagy5-0/+5
it was already defined for mips, but was missing from other archs
2012-12-19x86_64/bits/signal.h: fix typo in REG_CSGSFSrofl0r1-1/+1
2012-12-07fix trailing whitespace issues that crept in here and thereRich Felker1-9/+9
2012-12-06move signal.h REG_* macros under _GNU_SOURCE protectionRich Felker2-44/+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.
2012-12-06bits/signal.h: add register names for x86(_64)rofl0r2-0/+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.
2012-12-06add more arch-specific MAP_ macros to bits/mman.hrofl0r6-0/+24
these are also needed by qemu.
2012-12-06remove MAP_32 from non-x86 archsrofl0r3-3/+0
both kernel and glibc define it only on x86(_64).
2012-12-06add MAP_NORESERVE to bits/mman.hrofl0r6-0/+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.
2012-12-04fix regression in arm user.h that happened during big user.h changesRich Felker1-0/+1
2012-11-26remove stat member aliases from ppc-specific bits/stat.hRich Felker1-6/+0
if these are to be supported, they belong in the main stat.h, not repeated for each arch.
2012-11-25fixup mcontext stuff to expost gregset_t/fpregset_t as appropriateRich Felker6-10/+32
2012-11-25make sys/procfs.h mostly work on most archsRich Felker5-8/+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.
2012-11-25remove microblaze user.h incorrectly copied from armRich Felker1-40/+1
2012-11-23begin sys/user.h and sys/reg.h fixes for portsRich Felker4-98/+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.
2012-11-23fix powerpc ucontext, again..Rich Felker1-5/+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.
2012-11-23fix termios constants on mipsRich Felker1-10/+21
2012-11-23sigcontext/mcontext cleanup for arch-specific bitsRich Felker5-81/+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.
2012-11-23fix powerpc setjmp/longjmp to save/restore float regs; enlarge/align jmp_bufRich Felker1-1/+1
2012-11-23fix up leftover, incorrect NSIG definitions in arch-specific signal.hRich Felker5-5/+0
2012-11-23remove stuff that doesn't belong in powerpc 32-bit sigcontextRich Felker1-4/+0
these fields were wrongly copied from the kernel's ppc64 struct def
2012-11-21more ppc signal.h typedef order fixesRich Felker1-13/+13
2012-11-21fix misordered typedefs in ppc signal.hRich Felker1-2/+2
2012-11-21ppc signal/NSIG related fix (warning fix, redefinition)Rich Felker1-2/+1
2012-11-21add back NSIG, removed from powerpc in last commit, but for all archsRich Felker6-0/+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.
2012-11-21make powerpc signal.h namespace-clean for posix/isocRich Felker1-19/+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.
2012-11-21fix powerpc types to match abi, and some feature test issuesRich Felker3-7/+8
2012-11-21fix invalid usage of mcontext_t in powerpc signal.hrofl0r1-1/+1
2012-11-18fix breakage from introducing bits header for sys/io.hRich Felker6-6/+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.
2012-11-18add port io functions to sys/io.hRich Felker2-0/+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.
2012-11-18add missing const on powerpc FE_DFL_ENVRich Felker1-1/+1
2012-11-18fenv support for ppc, untestedRich Felker1-7/+28
based on code sent to the mailing list by nsz, with minor changes.
2012-11-18fcntl.h: O_SEARCH was missing for powerpcrofl0r5-24/+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.
2012-11-18ppc socket.h: add forgotten cmsghdrrofl0r1-0/+7
2012-11-16dynamic linking support for powerpcRich Felker1-8/+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.
2012-11-16fix ppc stat structure definitionRich Felker1-4/+3
2012-11-16fix powerpc termios.h and ioctl.hrofl0r2-192/+232
2012-11-15disable SO_REUSEPORT in sys/socket.hRich Felker1-1/+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.
2012-11-15ppc wchar_t is long, not intRich Felker1-1/+1
2012-11-14fix powerpc atomic compare-and-swap functionRich Felker1-6/+7
previous version did not compare at all; it was just a fancy atomic write. untested. further atomic fixes may be needed.
2012-11-14update ppc atomic code to match the endian-agnostic version on other archsRich Felker1-14/+6
2012-11-14fix wchar limits mistakenly copied from armRich Felker1-2/+2

these macros are supported by more compilers
