2014-05-14Fix erf underflow handling near 0 (bug 16516).Joseph Myers
Bug 16516 reports spurious underflows from erf (for all floating-point types), when the result is close to underflowing but does not actually underflow. erf (x) is about (2/sqrt(pi))*x for x close to 0, so there are subnormal arguments for which it does not underflow. The various implementations do (x + efx*x) (for efx = 2/sqrt(pi) - 1), for greater accuracy than if just using a single multiplication by an approximation to 2/sqrt(pi) (effectively, this way there are a few more bits in the approximation to 2/sqrt(pi)). This can introduce underflows when efx*x underflows even though the final result does not, so a scaled calculation with 8*efx is done in these cases - but 8 is not a big enough scale factor to avoid all such underflows. 16 is (any underflows with a scale factor of 16 would only occur when the final result underflows), so this patch changes the code to use that factor. Rather than recomputing all the values of the efx8 variable, it is removed, leaving it to the compiler's constant folding to compute 16*efx. As such scaling can also lose underflows when the final scaling down happens to be exact, appropriate checks are added to ensure underflow exceptions occur when required in such cases. Tested x86_64 and x86; no ulps updates needed. Also spot-checked for powerpc32 and mips64 to verify the changes to the ldbl-128ibm and ldbl-128 implementations. [BZ #16516] * sysdeps/ieee754/dbl-64/s_erf.c (efx8): Remove variable. (__erf): Scale by 16 instead of 8 in potentially underflowing case. Ensure exception if result actually underflows. * sysdeps/ieee754/flt-32/s_erff.c (efx8): Remove variable. (__erff): Scale by 16 instead of 8 in potentially underflowing case.

2014-05-14Reduce kernel-features.h duplication.Joseph Myers
This patch reduces duplication between different architectures' kernel-features.h files by making the architecture-independent file define various macros unconditionally (instead of only for a particular list of architectures), with the architecture-specific files then undefining the macros if necessary. Specifically, __ASSUME_O_CLOEXEC (O_CLOEXEC flag to open) and __ASSUME_SOCK_CLOEXEC (SOCK_NONBLOCK and SOCK_CLOEXEC flags to socket) are supported on all architectures as of 2.6.32 or the minimum kernel version for the architecture if later. For __ASSUME_IN_NONBLOCK, __ASSUME_PIPE2, __ASSUME_EVENTFD2, __ASSUME_SIGNALFD4 and __ASSUME_DUP3, the relevant syscalls were added for alpha in 2.6.33 but otherwise the features are available as of 2.6.32. For __ASSUME_UTIMES, support is everywhere in 2.6.32 except for asm-generic architectures and hppa. Although those were the main cases of duplication among kernel-features.h files, some other cases of unnecessary definitions were also cleaned up: the hppa file defined various macros that were either no longer used at all, or defined by the main file by default anyway, the ia64 file had duplicative definitions of __ASSUME_PSELECT and __ASSUME_PPOLL, while mips had such a definition of __ASSUME_IPC64. Really, rather than being defined in the main file then undefined for asm-generic architectures, __ASSUME_UTIMES should become an hppa-specific macro. Given that __ASSUME_ATFCTS and __ASSUME_UTIMENSAT are now always true, the only live __ASSUME_UTIMES conditional is in sysdeps/unix/sysv/linux/utimes.c, which is not used for asm-generic architectures. I think the desired state would be an hppa-specific file (that includes sysdeps/unix/sysv/linux/utimes.c if __ASSUME_UTIMES, and otherwise has fallback code), with the fallback code being removed from the main utimes.c. But I think that's most reasonably a separate cleanup once __ASSUME_ATFCTS and __ASSUME_UTIMESAT have both had conditional code cleaned up. Given this patch, I think it's straightforward to move non-ex-ports architectures to having their own kernel-features.h files, like ex-ports architectures, rather than conditionals in the main file (i.e., such a move won't require the architecture-specific file to contain anything that isn't genuinely architecture-specific), and would encourage architecture maintainers to do so. Tested x86_64 that the installed shared libraries are unchanged by this patch. Note that on some architectures this *will* cause __ASSUME_* macros to be defined in cases where they weren't previously but should have been (but this is just optimization, not a fix to a user-visible bug, so doesn't need a bug report in Bugzilla). * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Define unconditionally.

2014-05-14Clean up ARM old-ABI symbol versioning relics.Joseph Myers
This patch cleans up some symbol versioning code in the ARM port that exists only as relics of the old-ABI port, which was removed some time ago. The minimum symbol version in the ARM port is GLIBC_2.4 (the version where the EABI port was introduced). Thus, any SHLIB_COMPAT conditionals where the later version is 2.4 or later are obsolete and can be removed. In addition, there is no need to set symbol versions before 2.4 explicitly if the symbols would have a version of 2.4 by default anyway. This includes most of the entries in sysdeps/unix/sysv/linux/arm/Versions: those for GLIBC_2.0 are for libgcc unwind functions that aren't actually in ARM EABI glibc at all, while those for GLIBC_2.2 and GLIBC_2.3.3 are for functions which for the old-ABI port may have had versions different from the architecture-independent default, but where for EABI the default suffices (both the default and the version in that file map to 2.4, so the entries in that file do nothing). The GLIBC_2.1 entries are needed (architecture-specific functions), but it seems less confusing for those to say GLIBC_2.4, as the actual version those symbols in fact have. Various cases in the <fenv.h> functions where a function is defined as __fe* with an fe* versioned alias are cleaned up just to define fe* directly, as done e.g. on AArch64. If in future we actually need an __fe* name for use from C90 functions in libm as discussed recently, of course we can add one on all architectures and make the fe* name into a weak alias for that particular function, but for now the __fe* names aren't needed. In the case of posix_fadvise64, the __posix_fadvise64_l64 name and posix_fadvise64 alias are kept as __posix_fadvise64_l64 is used in posix_fadvise. (For that to be a namespace-clean use, posix_fadvise64 needs to be a *weak* alias not a strong one as at present, but that's an independent preexisting bug.) (There remain references to GLIBC_2_2 in sysdeps/unix/sysv/linux/arm/{msgctl.c,semctl.c,shmctl.c}. As those files are used by alpha which has a genuine 2.2 version for those functions, I think those references need to stay as-is.) Tested that the disassembly of installed shared libraries is unchanged by this patch (though function names shown in disassembly change to no longer have @@GLIBC_2.4, now those functions get versioned only by the version map and not redundantly at assembler time) and that the ABI tests pass. * sysdeps/arm/fclrexcpt.c (__feclearexcept): Rename to feclearexcept.

2014-05-12Clean up kernel version conditionals for pre-2.6.32 kernels.Joseph Myers
This patch does some initial cleanup, following the move to 2.6.32 minimum kernel version, by removing __LINUX_KERNEL_VERSION conditionals that are now always-true or always-false. In the case of __ASSUME_ARG_MAX_STACK_BASED, where the conditional used a kernel version that was itself in a macro, the associated sysconf.c code is also cleaned up and __ASSUME_ARG_MAX_STACK_BASED removed completely. Tested x86_64 that disassembly of installed shared libraries is unchanged by the patch. * sysdeps/unix/sysv/linux/kernel-features.h [__s390__] (__ASSUME_UTIMES): Do not condition on kernel version.

2014-05-09Silence a missing-noreturn warning for _Unwind_Resume.Roland McGrath
2014-05-09Include SSE state in i386 fenv_t (bug 16064).Joseph Myers
This patch fixes bug 16064, i386 fenv_t not including SSE state, using the technique suggested there of storing the state in the existing __eip field of fenv_t to avoid needing to increase the size of fenv_t and add new symbol versions. The included testcase, which previously failed for i386 (but passed for x86_64), illustrates how the previous state was buggy. This patch causes the SSE state to be included *to the extent it is on x86_64*. Where some state should logically be included but isn't for x86_64 (see bug 16068), this patch does not cause it to be included for i386 either. The idea is that any patch fixing that bug should fix it for both x86_64 and i386 at once. Tested i386 and x86_64. (I haven't tested the case of a CPU without SSE2 disabling the test.)

2014-05-09S/390: Port of lock elision to System/zDominik Vogt
Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built.
