* stdlib/tst-strtod-overflow: Bump timeout up yetMaciej W. Rozycki2014-07-032-1/+5
| | | | | | | | | This test case is very, especially on targets using soft-float or QEMU (where soft-float is used internally), and appears to be the only such outlier. Therefore rather than requiring to have TIMEOUTFACTOR set large enough globally, bump up the local scaling factor instead. * stdlib/tst-strtod-overflow.c (TIMEOUT): Bump up to 30.

* Fix Wundef warning for __STDC_VERSION__Siddhesh Poyarekar2014-07-032-1/+8
| | | | | | | | c4c4124473c187b5c4642611390897666c3d3970 added the _Noreturn macro for pre-C11 compilers, but it now throws a new Wundef warning during `make check` for __STDC_VERSION__ which gcc does not define by default. The following patch fixes this in line with other uses of __STDC_VERSION__ in the file.

* Fix -Wundef warning on PAGE_COPY_THRESHOLDSiddhesh Poyarekar2014-07-039-53/+62
| | | | | | | The PAGE_COPY_THRESHOLD macro is meant to be overridden by architecture-specific pagecopy.h, but it is currently done only by mach; all other architectures use the default. Check to see if the macro is defined in addition to whether it is set to a non-zero value.
* PowerPC: strcat optimization for PPC64/POWER7Vidya Ranganathan2014-07-027-4/+118
| | | | | | This patch adds an ifunc power7 strcat symbol that uses the logic on sysdeps/powerpc/strcat.c but call power7 strlen/strcpy symbols instead of default ones.

* hppa: Remove GLIBC_2.3 from librt.abilist.Carlos O'Donell2014-07-022-4/+3
| | | | | | This commit removes the aio_cancel and aio_cancel64 symbols at GLIBC_2.3 from the ABI baseline. The ABI baseline is now complete for hppa and considered stable.
* hppa: Add ABI baselines.Carlos O'Donell2014-07-0115-6/+3220
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following ABI baselines were tested against several old releases of debian and gentoo. Several problems were discovered and fixed as part of developing the ABI baselines. Firstly, libBrokenLocale on gentoo exports __ctype_get_mb_cur_max as @@GLIBC_2.0, but it should be @@GLIBC_2.2 since that's the minimum version defined in shlib-versions for hppa. I don't know when this broke, but master properly parses hppa's shlib-versions which clearly lists libBrokenLocale as defaulting to GLIBC_2.2. Therefore I'm accepting GLBIC_2.2 as the correct version for this symbol and setting the baseline to that, despite the fact that the present distribution is wrong. I don't expect that any new applications should be using libBrokenLocale, so it should match the oldest behaviour which is to export a GLIBC_2.2 symbol. For example in debian's 2.7 has it at version GLIBC_2.2. Secondly, aio_cancel and aio_cancel64 previously had a compat symbol at version @GLIBC_2.1 with a new symbol at @@GLIBC_2.3[1]. During the Linuxthreads to NPTL transition the file aio_cancel.c was lost for hppa and that resulted in just @@GLIBC_2.1 versions of these symbols being exported. The @@GLIBC_2.1 version works correctly and uses the right value of ECANCELLED. Therefore if I were to fix this today it might break correctly working applications using aio_cancel*@GLIBC_2.1 by causing those to use the old aio_cancel that used the older value of ECANCELLED. Thus the best option is to accept that the ABI changed and ignore older applications in favour of newer applications. The best thing to do is cleanup the version files (included in the patch). The rest of the ABI was as expected (ignoring __p_type_syms size change in 2008).

* Remove MULTI_PTRS_ARE_ALIASES in dns-hosts.cSiddhesh Poyarekar2014-07-012-22/+7
| | | | | | | | | | | | | | | | The code in gethnamaddr.c for gethostbyaddr used and set this macro to allow multiple PTR records to be added as aliases. This was useful for gethostbyaddr since it returns a hostent structure, which can return aliases. The gethnamaddr.c source however is unused in glibc since pretty much forever. Instead, the DNS lookup bits for gethostbyaddr (as well as getnameinfo) are implemented in dns-hosts.c and in that implementation all but one (the first one) of the multiple PTR records are ignored. Since gethnamaddr.c is essentially dead code, ignore that implementation and replace the MULTI_PTRS_ARE_ALIASES bit with a comment mentioning that bind adds PTR records as aliases while we don't.

* Fix ldbl-128 expm1l spurious underflow (bug 16539).Joseph Myers2014-06-302-0/+10
| | | | | | | | | | | | | | | This patch fixes spurious underflows from ldbl-128 expm1l, as reported in <https://sourceware.org/ml/libc-alpha/2014-06/msg00835.html> and exposed by the tests added for such a bug in the x86 / x86-64 version.

* Rename soft-fp extended.h, op-common.h variables to avoid risk of shadowing.Joseph Myers2014-06-303-258/+317
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In <https://sourceware.org/ml/libc-alpha/2013-06/msg00851.html>, I fixed a bug caused by multiple soft-fp macros using the same variable names, resulting in shadowing when one macro called another that used the same variable name, with an argument involving the variable in the outer macro. The fix was to rename the local variables so their names included the containing macro name, to ensure uniqueness. I noted then that this would make sense more systematically for all variables in any soft-fp macro. Since then, I've used such variable names in new soft-fp macros. This patch now converts existing macros in extended.h and op-common.h to use this convention. (op-[1248].h are intended to be converted separately.) (Name conflicts could arise for label names as well, but because those are function-scope in C any such conflict will give an immediate compile error rather than a subtle bug, so there's no need for preemptive renaming in that case.) Tested for powerpc32 (soft-float) and mips64 that this makes no change to the disassembly of installed shared libraries. * soft-fp/extended.h (FP_UNPACK_RAW_E): Rename local variables to include macro name.

* Fix ldbl-128 powl sign of result in overflow / underflow cases (bug 17097).Joseph Myers2014-06-293-14/+21
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 17097, ldbl-128 powl producing overflowing / underflowing results with positive sign when the result should have been negative. This was shown up by the tests in non-default rounding modes added by my patch for bug 16315, but isn't actually limited to non-default rounding modes: rather, when rounding to nearest the wrappers produced a result with the correct sign and so always hid the bug unless -lieee was used to disable the wrappers. The problem is that in the cases where Y is large enough that the result overflows or underflows for X not very close to 1, but not large enough to overflow or underflow for all X != +/- 1 (in the latter case Y is always an even integer), a positive overflowing / underflowing result is always returned, rather than one with the correct sign. This patch moves the relevant part of computation of the sign earlier and returns a result of the correct sign. Tested for mips64. [BZ #17097] * sysdeps/ieee754/ldbl-128/e_powl.c (__ieee754_powl): Return result with correct sign in case of exponents that produce overflow except for X very close to 1.

* Remove shlib-versions ABI names support.Joseph Myers2014-06-276-24/+9
| | | | | | | | | | | | | | | | | | | | shlib-versions files can contain ABI lines that map triplets to a canonical ABI name. This name was once used for various purposes where test baseline files for different ABIs went in a single directory; now these purposes use sysdeps files, generation of headers which have per-ABI variants uses abi-variants and related Makefile variables and the shlib-versions ABI names are unused. This patch duly removes those lines and associated build system support for them. Tested for x86_64 (both a full testsuite run and confirming the installed shared libraries are unchanged by the patch). * Makeconfig ($(common-objpfx)soversions.mk): Do not generate abi-name definition. * scripts/soversions.awk: Do not handle or generate ABI lines. * shlib-versions: Remove ABI entries. * sysdeps/powerpc/nofpu/shlib-versions: Remove file. * sysdeps/x86_64/x32/shlib-versions: Remove ABI entry.

* Correctly report nscd child process status (BZ #17092)Arjun Shankar2014-06-273-10/+20
| | | | | | | | | | The nscd parent process returns the result of a `wait' call rather than the exit status of the child it waits for. These two aren't exactly the same. In my case (and probably on most machines), the exit status is in the 2nd LSB of the result of `wait', and so: e.g. if the nscd child process returns 1, the parent returns 1 << 8, which Bash happily reports as 0.
* Remove relro configure test.Joseph Myers2014-06-279-194/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the configure test for working -z relro. The use of -z relro in Makeconfig became unconditional with commit 2e6ab1df44c412bb9d30b26a4d8a679150a7e375 Author: Ulrich Drepper <drepper@redhat.com> Date: Sat Oct 28 06:44:04 2006 +0000 Remove conditional code which now is unnecessary. (commit reference from git://repo.or.cz/glibc/history), so since then the configure test has not controlled anything about how glibc is built - simply about whether configure succeeds and allows a build to be attempted. The test for whether the option did something useful (as opposed to whether it exists - which we can certainly just assume by now) was originally added in <https://sourceware.org/ml/libc-hacker/2004-09/msg00069.html> to disable the option in a case when it did nothing useful on ia64 (as a result of something deliberate in the linker on ia64). Since 2006 that disabling has been of no effect, and given that the current test does not set libc_relro_required for ia64, it does nothing whatever useful for the original motivating case. Also at around the same time in 2006 the test was made to give an error for missing or broken -z relro support on various architectures. So effectively all the test does now is verify that, on certain architectures, the linker has not been changed deliberately to make the option ineffective. I see no apparent reason why such a change should be expected, or why the build should be stopped if it were to be made (any more than we disallow build on ia64); I think we can trust binutils patch review to point out the consequences of any change to COMMONPAGESIZE setting. The only thing that might now make sense would be disabling the -z relro use on an architecture-specific basis if there were an architecture-specific reason to consider that to make sense; it would be for the ia64 maintainer to decide if that makes sense for ia64 at present, but I think that could be done through sysdeps Makefiles - no special configure tests needed. Tested for x86_64 that this patch makes no change to the installed shared libraries. Together with <https://sourceware.org/ml/libc-alpha/2014-06/msg00788.html> (pending review) this substantially eliminates architecture-specific cases from architecture-independent configure.ac files. There remains an i386 case in sysdeps/mach/hurd/configure.ac that should properly move to the i386 subdirectory.

* Fix yn overflow handling in non-default rounding modes (bug 16561, bug 16562).Joseph Myers2014-06-2711-261/+389
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bugs 16561 and 16562, bad results of yn in overflow cases in non-default rounding modes, both because an intermediate overflow in the recurrence does not get detected if the result is not an infinity and because an overflowing result may occur in the wrong sign. The fix is to set FE_TONEAREST mode internally for the parts of the function where such overflows can occur (which includes the call to y1 - where yn is used to compute a Bessel function of order -1, negating the result of y1 isn't correct for overflowing results in directed rounding modes) and then compute an overflowing value in the original rounding mode if the to-nearest result was an infinity. Tested x86_64 and x86 and ulps updated accordingly. Also tested for mips64 and powerpc32 to test the ldbl-128 and ldbl-128ibm changes. (The tests for these bugs were added in my previous y1 patch, so the only thing this patch has to do with the testsuite is enable yn testing in all rounding modes.)
