* 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.
* ppc wchar_t is long, not intRich Felker2012-11-151-1/+1
|
* fix powerpc atomic compare-and-swap functionRich Felker2012-11-141-6/+7
| | | | | previous version did not compare at all; it was just a fancy atomic write. untested. further atomic fixes may be needed.
* update ppc atomic code to match the endian-agnostic version on other archsRich Felker2012-11-141-14/+6
|
* fix wchar limits mistakenly copied from armRich Felker2012-11-141-2/+2

* inline syscalls for microblazeRich Felker2012-10-181-0/+97
|
* better support for reverse-endian variants of arm/mips/microblazeRich Felker2012-10-183-0/+12
| | | | these macros are supported by more compilers
* floating point environment/exceptions support for mipsRich Felker2012-10-181-3/+13
|
* microblaze TLS relocation support, completely untestedRich Felker2012-10-151-0/+6
|
* add support for TLS variant I, presently needed for arm and mipsRich Felker2012-10-157-11/+33
| | | | | | | | | | | | | | | | | | | | | | despite documentation that makes it sound a lot different, the only ABI-constraint difference between TLS variants II and I seems to be that variant II stores the initial TLS segment immediately below the thread pointer (i.e. the thread pointer points to the end of it) and variant I stores the initial TLS segment above the thread pointer, requiring the thread descriptor to be stored below. the actual value stored in the thread pointer register also tends to have per-arch random offsets applied to it for silly micro-optimization purposes. with these changes applied, TLS should be basically working on all supported archs except microblaze. I'm still working on getting the necessary information and a working toolchain that can build TLS binaries for microblaze, but in theory, static-linked programs with TLS and dynamic-linked programs where only the main executable uses TLS should already work on microblaze. alignment constraints have not yet been heavily tested, so it's possible that this code does not always align TLS segments correctly on archs that need TLS variant I.
* ensure pointer decay in inline-asm arg for i386 syscall6Rich Felker2012-10-131-1/+1
| | | | | | | | this is actually a rather subtle issue: do arrays decay to pointers when used as inline asm args? gcc says yes, but currently pcc says no. hopefully this discrepency in pcc will be fixed, but since the behavior is not clearly defined anywhere I can find, I'm using an explicit operation to cause the decay to occur.
