* Fix __ASSUME_RECVMMSG issues (bug 16610).Joseph Myers2014-02-2010-6/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the issues for accept4, __ASSUME_RECVMMSG is also confused about whether it relates to function availability or socketcall operation availability; this is now bug 16610. Nothing actually tests __ASSUME_RECVMMSG for function availability, but implicit in the definition in kernel-features.h is the idea that it makes sense when the syscall is available and socketcall is not being used. As with accept4, there are architectures where the syscall was added later than the socketcall operation, meaning that assuming glibc is built with recent enough kernel headers, it does not attempt to use socketcall for these operations and __ASSUME_RECVMMSG gets defined for kernels >= 2.6.33 even when the syscall was only added later. This patch splits the macro into separate macros like those used for accept4; having similar macro structure in both cases (and for sendmmsg once I've dealt with that) seems likely to be less confusing than having a different structure on the basis of nothing actually needing to assume the recvmmsg function works. Appropriate definitions are added for all architectures. Architecture-specific note: Tile's kernel-features.h says "TILE glibc support starts with 2.6.36", which is accurate in that 2.6.36 was the first kernel version with Tile support, and on that basis I've made that header define __ASSUME_RECVMMSG_SYSCALL unconditionally. However, Tile's configure.ac has arch_minimum_kernel=2.6.32. Since arch_minimum_kernel is meant to reflect only kernel.org kernel versions, I think that should change to 2.6.36. (If using glibc with kernel versions from before a port went in kernel.org, it's your responsibility to change arch_minimum_kernel in a local patch, and at the same time to adjust any __ASSUME_* definitions that may not be correct for your older kernel; for developing the official glibc it should only ever be necessary to consider what official kernel.org releases support.) Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch.

As previously noted, __ASSUME_ACCEPT4 is used in two ways: * In OS-independent code, to mean "accept4 can be assumed to work rather than fail with ENOSYS". It doesn't matter whether it's implemented with socketcall or a separate syscall. * In Linux-specific code, to mean "the socketcall multiplex syscall can be assumed to handle the accept4 operation. When used in Linux-specific code, it *never* refers to anything relating to the accept4 syscall, only to the socketcall multiplexer. This patch splits the macro into separate __ASSUME_ACCEPT4_SOCKETCALL, __ASSUME_ACCEPT4_SYSCALL and __ASSUME_ACCEPT4 to clarify the different cases involved. A macro __ASSUME_SOCKETCALL is added for convenience in writing logic relating to all socketcall architectures. In addition, to address the issue of architectures where socketcall support for accept4 was added before a separate syscall was added (and so the separate syscall should not be used unless known to be present or fallback to socketcall is available), a fourth macro __ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL is added to indicate that the syscall became available at the same time as socketcall support. This is then used in the relevant places in a conditional determining whether to undefine __NR_accept4 (the simple approach to avoiding the syscall's presence causing problems; I didn't try to implement runtime fallback from the syscall to socketcall). Architecture-specific note: alpha defined __ASSUME_ACCEPT4 for 2.6.33 and later, but actually the syscall was added for alpha in 3.2, so this patch uses the correct condition for __ASSUME_ACCEPT4_SYSCALL there. Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch.

* Move tests of clog10 from libm-test.inc to auto-libm-test-in.Joseph Myers2014-02-192-8/+6730
| | | | | | | | | | | | | | | | | | This patch moves tests of clog10 to auto-libm-test-in. Note that this means gen-auto-libm-tests will now depend on the recent MPC 1.0.2 release which added a fix for a bug that made gen-auto-libm-tests hang for clog10. (It still can't conveniently be used for cacos cacosh casin casinh catan catanh csin csinh because of extreme slowness of those functions for special cases in MPC; at least some slow cases of csin / csinh are fixed in MPC trunk, but not in a release.)

* Fix gen-auto-libm-tests sticky bit setting for negative results.Joseph Myers2014-02-182-0/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | gen-auto-libm-tests has a bug in the logic for setting a sticky bit based on the ternary value from MPFR: it is correct for positive results, but for negative results mpz_setbit acts as if a two's complement representation is used, whereas the low bit needs setting based on the sign-magnitude representation GMP actually uses. (This showed up in converting fma tests to use auto-libm-test-in / gen-auto-libm-tests.) This patch fixes the problem by negating the mpz_t value to set its low bit. There are lots of changes to auto-libm-test-out (mainly 1ulp fixes to ldbl-128 expected results), but only a few ulps updates are needed on x86 / x86_64. In one case, a corrected expectation showed up a spurious underflow exception where the correct result is slightly outside the underflowing range. Tested x86_64 and x86 and ulps updated accordingly. * math/gen-auto-libm-tests.c (adjust_real): Ensure integers are non-negative before setting low bit. * math/auto-libm-test-in: Mark one asin test possibly having spurious underflow. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.

* Update MIPS math-tests.h for GCC 4.9 using soft-fp.Joseph Myers2014-02-132-4/+2200
| | | | | | | | | | | | | | | | GCC trunk now uses soft-fp for MIPS64 long double, so supporting integration with hardware exceptions and rounding modes. This patch updates MIPS math-tests.h accordingly not to disable exception and rounding mode tests in this case.

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-1217-26/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

* soft-fp: support after-rounding tininess detection.Joseph Myers2014-02-1210-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Merge MIPS dl-lookup.c into generic file.Joseph Myers2014-02-112-1029/+15
| | | | | | | | | | | | | | | | | | | | | | | 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.

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 tilegx, tilepro, and linux-generic from ports to libc.Chris Metcalf2014-02-10271-0/+28727
| | | | | | | | | | | | | | | | 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. 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.

* Fix tst-setgetname for Linux kernels < 2.6.33.Carlos O'Donell2014-02-051-0/+6
| | | | | | | | Support for /proc/self/task/$tid/comm as added in Linux 2.6.33, therefore since the test tst-setgetname relies on this functionality to operate we must skip the test in kernels < 2.6.33. We wrap the checks with __ASSUME_PROC_PID_TASK_COMM such that in the future when we move arch_minimum_kernel to 2.6.33 we can remove this code.

| | | | | | | When i386 and x86-64 mathinline.h was merged into a single mathinline.h, "gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse and SSE2 is enabled. It is a regression on x86-64. We should check __SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions.

* PowerPC: Fix gettimeofday ifunc selectionAdhemerval Zanella2014-01-202-4/+10
| | | | | | | | | | | | The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where __vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal version used within GLIBC) to use the system call version instead of the vDSO one. This patch changes the check if vDSO is available to get its value directly instead of rely on __vdso_gettimeofday. This patch changes it by getting the vDSO value directly. It fixes BZ#16431.
* s390: implement sotruss supportMike Frysinger2014-01-161-0/+62
| | | | | | | | | | | | | See commit 41b1792698a335d3a85381921a84a16e9635f36a for testcase. Note: while this works on s390x, the s390 code hangs when using -e. But it hangs regardless of this code (the hang seems to occur before the exit func is even called). I didn't look too closely at it as it seems to be an issue external to this file, so this code shouldn't make the situation any worse.

* PowerPC: Fix ftime gettimeofday internal call returning bogus dataAdhemerval Zanella2014-01-162-4/+36
| | | | | | | | | | | | This patches fixes BZ#16430 by setting a different symbol for internal GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol is defined as hidden (which is the case for gettimeofday and time) the compiler will create local branches (symbol@local) and linker will not create PLT calls (required for IFUNC). This will leads to internal symbol calling the IFUNC resolver instead of the resolved symbol. For PPC64 this behavior does not occur because a call to a function in another translation unit might use a different toc pointer thus requiring a PLT call.
