* Make ABI tests generate .out files.Joseph Myers2014-02-123-10/+21
| | | | | | | | | | | | | | | | | | | If you rerun "make check" in a tree where some tests have already been run, it will rerun ABI tests because those do not create an output file. This patch changes those tests to create .out files so they only get rerun if the dependencies (on the ABI baselines and the generated .symlist files) indicate they should be rerun. Tested x86_64. * Makerules (check-abi-%): Change target to $(objpfx)check-abi-%.out. (check-abi target): Update dependencies. (check-abi-pattern variable): Redirect output of diff to $@. (check-abi variable): Likewise. * elf/Makefile (check-abi): Update dependencies.
* soft-fp: support after-rounding tininess detection.Joseph Myers2014-02-1213-4/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IEEE 754-2008 defines two ways in which tiny results can be detected, "before rounding" (based on the infinite-precision result) and "after rounding" (based on the result when rounded to normal precision as if the exponent range were unbounded). All binary operations on an architecture must use the same choice of how tininess is detected. soft-fp has so far implemented only before-rounding tininess detection. This patch adds support for after-rounding tininess detection. A new macro _FP_TININESS_AFTER_ROUNDING is added that sfp-machine.h must define (soft-fp is meant to be self-contained so the existing tininess.h files aren't used here, though the information going in sfp-machine.h has been taken from them). The soft-fp macros dealing with raising underflow exceptions then handle the cases where the choice matters specially, rounding a copy of the input to the appropriate precision to see if a value that's tiny before rounding isn't tiny after rounding. Tested for mips64 using GCC trunk (which now uses soft-fp on MIPS, so supporting exceptions and rounding modes for long double where not previously supported - this is the immediate motivation for doing this patch now) together with (a) a patch to sysdeps/mips/math-tests.h to enable exceptions / rounding modes tests for long double for GCC 4.9 and later, and (b) corresponding changes applied to libgcc's soft-fp and sfp-machine.h files. In the libgcc context this is also tested on x86_64 (also an after-rounding architecture) with testcases for __float128 that I intend to add to the GCC testsuite when updating soft-fp there. (To be clear: this patch does not fix any glibc bugs that were user-visible in past releases, since after-rounding architectures didn't use soft-fp in any affected case with support for floating-point exceptions - so there is no corresponding Bugzilla bug. Rather, it works together with the GCC changes to use soft-fp on MIPS to allow previously absent long double functionality to work properly, and allows soft-fp to be used in glibc on after-rounding architectures in cases where it couldn't previously be used.) * soft-fp/op-common.h (_FP_DECL): Mark exponent as possibly unused. (_FP_PACK_SEMIRAW): Determine tininess based on rounding shifted value if _FP_TININESS_AFTER_ROUNDING and unrounded value is in subnormal range. (_FP_PACK_CANONICAL): Determine tininess based on rounding to normal precision if _FP_TININESS_AFTER_ROUNDING and unrounded value has largest subnormal exponent. * soft-fp/soft-fp.h [FP_NO_EXCEPTIONS] (_FP_TININESS_AFTER_ROUNDING): Undefine and redefine to 0. * sysdeps/aarch64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): New macro. * sysdeps/alpha/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/arm/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/mips/mips64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/mips/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/powerpc/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sh/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sparc/sparc32/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sparc/sparc64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/tile/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise.

* Remove _BSD_SOURCE and _SVID_SOURCE.Joseph Myers2014-02-1110-43/+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.

* Merge MIPS dl-lookup.c into generic file.Joseph Myers2014-02-114-1029/+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.

* Relocate AArch64 from ports to libc.Marcus Shawcroft2014-02-11176-1/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Move shared umount.c from hppa to mips.Joseph Myers2014-02-104-31/+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.

* Remove mips dependency on alpha.Joseph Myers2014-02-102-1/+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.
* Move tilegx, tilepro, and linux-generic from ports to libc.Chris Metcalf2014-02-10275-7/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've moved the ARM port from ports to the main sysdeps hierarchy.

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.
