2014-02-11Remove _BSD_SOURCE and _SVID_SOURCE.Joseph Myers10-43/+51
This is a minimal patch to remove _BSD_SOURCE and _SVID_SOURCE from the documented user API, making them into aliases for _DEFAULT_SOURCE with a #warning given, but keeping most of the features.h logic using those macros and all the exising __USE_* conditionals, on the basis that all the consequent cleanups will go in followup patches. Tested x86_64. * include/features.h: Update comment documenting feature test macros. [_BSD_SOURCE || _SVID_SOURCE]: Give #warning. Define _DEFAULT_SOURCE. * manual/creature.texi (_BSD_SOURCE): Remove documentation. (_SVID_SOURCE): Likewise. (_DEFAULT_SOURCE): Update description of default features. (Feature Test Macros): Don't mention _SVID_SOURCE in conjunction with _GNU_SOURCE. * manual/filesys.texi (__ftw_func_t): Do not refer to _BSD_SOURCE. (S_ISVTX): Likewise. * manual/math.texi (Mathematical Constants): Likewise. * manual/signal.texi (Interrupted Primitives): Likewise. * manual/startup.texi (putenv): Do not refer to _SVID_SOURCE. * math/test-matherr.c (_SVID_SOURCE): Do not define. * sysvipc/sys/ipc.h [__USE_SVID && !__USE_XOPEN && __GNUC__ >= 2]: Don't refer to _SVID_SOURCE in warning text.

2014-02-11Merge MIPS dl-lookup.c into generic file.Joseph Myers4-1029/+31
MIPS has its own version of dl-lookup.c to deal with differences between undefined symbol semantics in the PIC and non-PIC ABIs. This is often liable to get out of date with respect to the generic file (for example, the recent __builtin_expect changes didn't cover ports, and it's not obvious to anyone changing dl-lookup.c that there would be architecture-specific versions). This patch adds a macro that dl-machine.h can define that is used in the appropriate place in dl-lookup.c, so that MIPS no longer needs its own version of that file. Tested for mips64 that the only changes to disassembly of installed shared libraries appear to be ld.so changes attributable to different line numbers and paths in assertions. * elf/dl-lookup.c (ELF_MACHINE_SYM_NO_MATCH): Define if not already defined. (do_lookup_x): Use ELF_MACHINE_SYM_NO_MATCH. * sysdeps/mips/dl-lookup.c: Remove. * sysdeps/mips/dl-machine.h (ELF_MACHINE_SYM_NO_MATCH): New macro.

2014-02-11Relocate AArch64 from ports to libc.Marcus Shawcroft176-1/+21
This patch moves the AArch64 port to the main sysdeps hierarchy. The move is essentially: git mv ports/sysdeps/aarch64 sysdeps/aarch64 git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64 The README is updated and I've updated ChangeLog.aarch64 along the lines of the ARM move. The AArch64 build has been tested to confirm that there were no changes in objdump -dr output or the shared objects.

2014-02-10Fix whitespace in MIPS files to allow move.Joseph Myers2-2/+0
2014-02-10Move mips from ports to libc.Joseph Myers366-4/+23
I've moved the MIPS port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/mips sysdeps/mips git mv ports/sysdeps/unix/mips sysdeps/unix/mips git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.mips similar to those in other files. Tested that disassembly of installed shared libraries for mips is the same before and after this patch (except for ld.so where paths in assertions are involved, as for arm). * sysdeps/mips: Move directory from ports/sysdeps/mips. * sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory from ports/sysdeps/unix/sysv/linux/mips. * README: Update listing for mips-*-linux-gnu and mips64-*-linux-gnu. * sysdeps/mips: Move directory to ../sysdeps/mips. * sysdeps/unix/mips: Move directory to ../sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory to ../sysdeps/unix/sysv/linux/mips.
2014-02-10Move shared umount.c from hppa to mips.Joseph Myers4-31/+43
This patch prepares for moving mips from ports to libc by reversing the #include ordering between mips and hppa. Reversing #include ordering for umount.c is the conservative change in preparation for moving the mips port. In fact, it appears there are several redundant umount.c files all implementing umount in terms of the umount2 syscall; I've filed bug 16552 for eliminating that redundancy properly. Tested that disassembly of shared libraries for mips (o32, n32, n64) is the same before and after this patch. * sysdeps/unix/sysv/linux/hppa/umount.c: Move to sysdeps/unix/sysv/linux/mips/mips64/umount.c and #include that file. * sysdeps/unix/sysv/linux/mips/mips64/umount.c: Move from sysdeps/unix/sysv/linux/hppa/umount.c instead of #include of that file.

2014-02-10Remove mips dependency on alpha.Joseph Myers2-1/+7
This patch removes an unnecessary dependency of the mips port on alpha by including a powerpc file directly where previously the mips file included the alpha one which then included the powerpc one. * sysdeps/unix/sysv/linux/mips/ipc_priv.h: Directly include sysdeps/unix/sysv/linux/powerpc/ipc_priv.h instead of via sysdeps/unix/sysv/linux/alpha/ipc_priv.h.
2014-02-10Move tilegx, tilepro, and linux-generic from ports to libc.Chris Metcalf275-7/+41
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects.

2014-02-08Move arm from ports to libc.Joseph Myers269-1/+19
I've moved the ARM port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/arm sysdeps/arm git mv ports/sysdeps/unix/arm sysdeps/unix/arm git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.arm similar to that at the top of ChangeLog.powerpc. There is deliberately no NEWS change, as I think it makes the most sense to put in a general note above all ports having moved if we can achieve that for 2.20. Tested that disassembly of installed shared libraries for arm is the same before and after this patch, except for data (not instructions) in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the path by which that file is found, and so by which it appears in the assertion message, changes as a result of the move). * sysdeps/arm: Move directory from ports/sysdeps/arm. * sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm. * sysdeps/unix/sysv/linux/arm: Move directory from ports/sysdeps/unix/sysv/linux/arm. * README: Update listing for arm-*-linux-gnueabi. ports/ChangeLog.arm: * sysdeps/arm: Move directory to ../sysdeps/arm. * sysdeps/unix/arm: Move directory to ../sysdeps.arm. * sysdeps/unix/sysv/linux/arm: Move directory to ../sysdeps/unix/sysv/linux/arm.
2014-02-08Move shared sysdeps files from alpha to arm.Joseph Myers12-127/+160
This patch prepares for moving arm from ports to libc (see overall plan at <https://sourceware.org/ml/libc-alpha/2014-01/msg00373.html> and discussion of ordering starting at <https://sourceware.org/ml/libc-ports/2014-01/msg00071.html>) by reversing the #include order between arm and alpha, so that arm can move early as a test for the general pattern of moving architectures. MicroBlaze files (that used the same alpha files) were made to include the files directly from their new locations rather than indirecting. Tested that disassembly of installed shared libraries for arm is the same before and after this patch. * sysdeps/unix/sysv/linux/alpha/msgctl.c: Move to sysdeps/unix/sysv/linux/arm/msgctl.c and #include that file. * sysdeps/unix/sysv/linux/alpha/semctl.c: Move to sysdeps/unix/sysv/linux/arm/semctl.c and #include that file. * sysdeps/unix/sysv/linux/alpha/shmctl.c: Move to sysdeps/unix/sysv/linux/arm/shmctl.c and #include that file. * sysdeps/unix/sysv/linux/arm/msgctl.c: Move from sysdeps/unix/sysv/linux/alpha/msgctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/arm/semctl.c: Move from sysdeps/unix/sysv/linux/alpha/semctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/arm/shmctl.c: Move from sysdeps/unix/sysv/linux/alpha/shmctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/microblaze/msgctl.c: Include sysdeps/unix/sysv/linux/arm/msgctl.c instead of sysdeps/unix/sysv/linux/alpha/msgctl.c. * sysdeps/unix/sysv/linux/microblaze/semctl.c: Include sysdeps/unix/sysv/linux/arm/semctl.c instead of sysdeps/unix/sysv/linux/alpha/semctl.c. * sysdeps/unix/sysv/linux/microblaze/shmctl.c: Include sysdeps/unix/sysv/linux/arm/shmctl.c instead of sysdeps/unix/sysv/linux/alpha/shmctl.c.

2014-02-06BZ #16529: Fix pedantic warning with netinet/in.h.Carlos O'Donell3-2/+7
When compiling with pedantic the following warning is seen: gcc -Wall -pedantic -O0 -o test test.c In file included from test.c:3:0: /path/inet/netinet/in.h:111:21: warning: comma at end of \ enumerator list [-Wpedantic] IPPROTO_MH = 135, /* IPv6 mobility header. */ ^ It is valid C99 to have a trailing comma after the last item in an enumeration. However it is not valid C90. If possible glibc attempts to keep all headers C90 + long long without requiring C99 features. In this case it's easy to fix the headers and it removes the warning seem with -pedantic.
