2014-01-03Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390).Joseph Myers3-1/+8
This patch fixes bug 16390, incorrect signs of zero results from ldbl-128ibm atan2l, soft-float only. The problem is a longstanding GCC bug with fabsl not being correct for signed zero for soft float, and the fix is using -fno-builtin-fabsl as a workaround, as already done for various other source files. Tested powerpc-nofpu. * sysdeps/powerpc/nofpu/Makefile [$(subdir) = math] (CFLAGS-e_atan2l.c): Use -fno-builtin-fabsl.

2014-01-03Regenerate powerpc-nofpu ulps.Joseph Myers2-963/+7501
2014-01-03Mark various libm tests with xfail-rounding:ldbl-128ibm.Joseph Myers3-1744/+1759
This patch marks various libm tests with xfail-rounding:ldbl-128ibm, where the failures appear to relate to GCC bug 59666 (bad libgcc handling of directed rounding), so as to allow clean libm-test-ulps regeneration without needing to edit out large ulps for various functions manually. Note that this only deals with the cases problematic for ulps regeneration. There are plenty of test failures left that do not affect ulps regeneration - results that are infinities or NaNs but should be finite, or vice versa, and missing and spurious exceptions - which should also be resolved during the release testing period. Tested for powerpc32 (hard float). * math/auto-libm-test-in: Mark various tests with xfail-rounding:ldbl-128ibm. * math/auto-libm-test-out: Regenerated.
2014-01-02Fix ldbl-128ibm logl inaccuracy (bug 16386).Joseph Myers3-1/+14
This patch fixes bug 16386, ldbl-128ibm logl inaccuracy (with consequent inaccuracy for lgammal) for arguments where the high double is subnormal, which showed up while attempting to regenerate ulps for powerpc-nofpu for 2.19. The problem here is logic failing to allow for subnormals when calculating the exponent of the argument. Tested for powerpc-nofpu. * sysdeps/ieee754/ldbl-128ibm/e_logl.c (__ieee754_logl): Adjust numbers with subnormal high part when calculating exponent.
2014-01-02Fix ldbl-128ibm asinhl inaccuracy (bug 16385).Joseph Myers3-2/+6
This patch fixes bug 16385, ldbl-128ibm asinhl inaccuracy, which showed up while attempting to regenerate ulps for powerpc-nofpu for 2.19. The problem here was use of fabs instead of fabsl meaning large arguments were reduced to the precision of double. Tested for powerpc-nofpu. * sysdeps/ieee754/ldbl-128ibm/s_asinhl.c (__asinhl): Use fabsl not fabs.
2014-01-02Fix ldbl-128ibm acoshl inaccuracy (bug 16384).Joseph Myers3-3/+10
This patch fixes bug 16384, ldbl-128ibm acoshl inaccuracy, which showed up while attempting to regenerate ulps for powerpc-nofpu for 2.19. There were two separate problems, use of __log1p instead of __log1pl and an insufficiently accurate constant value for log 2 (which this patch replaces by use of M_LN2l), each of which could cause substantial inaccuracy in affected cases. Tested for powerpc-nofpu. * sysdeps/ieee754/ldbl-128ibm/e_acoshl.c (ln2): Initialize with M_LN2l. (__ieee754_acoshl): Use __log1pl not __log1p.

2014-01-02Fix return code from getent netgroup when the netgroup is not found (bz #16366)Siddhesh Poyarekar3-30/+67
nscd incorrectly returns a success even when the netgroup in question is not found and adds a positive result in the cache. this patch fixes this behaviour by adding a negative lookup entry to cache and returning an error when the netgroup is not found.
2014-01-02Fix infinite loop in nscd when netgroup is empty (bz #16365)Siddhesh Poyarekar3-4/+11
Currently, when a user looks up a netgroup that does not have any members, nscd goes into an infinite loop trying to find members in the group. This is because it does not handle cases when getnetgrent returns an NSS_STATUS_NOTFOUND (which is what it does on empty group). Fixed to handle this in the same way as NSS_STATUS_RETURN, similar to what getgrent does by itself.

2013-12-31Benchmark inputs for cos and sinSiddhesh Poyarekar3-12/+5303
Add a comprehensive number of inputs for all branches in sin and cos computation, excluding the fast paths. This also adds a number of inputs for the multiple precision slow paths.
2013-12-31benchmark inputs for atanSiddhesh Poyarekar2-5/+805
Add a more comprehensive set of inputs for the atan function. I have also fixed the name on the multiple precision fallback inputs (I couldn't find any new inputs there) to reflect the fact that the fallback is only 144bits and not 768bits as I had earlier mentioned.

2013-12-23Define __CORRECT_ISO_CPP_STRING_H_PROTO correctly for Clang.Brooks Moses3-4/+19
In the string/string.h and string/strings.h headers, we have a couple of macros that "tell the caller that we provide correct C++ prototypes" according to the comment; they are used to determine whether to wrap some prototypes in "extern "C++"" (and provide multiple overloads of them, and some other magic) when __cplusplus is defined. The macros are set to check for sufficiently-recent GCC versions (4.4 and later), but this is not the right check for non-GCC compilers. In particular, these macros should also be set when using Clang -- if they are not set, then Clang will be unable to correctly diagnose a number of subtle bugs that will be errors in GCC compilations. As per discussion on earlier versions of this patch, rather than restrict the fix to Clang per se, we assume that all C++ compilers that claim to fully support C++98 are using a standard-conforming C++ standard library, which seems pretty reasonable. Clang has been providing an appropriate value of __cplusplus since May 2012.

2013-12-24Fix race in free() of fastbin chunk: BZ #15073Maxim Kuvyrkov3-19/+30
Perform sanity check only if we have_lock. Due to lockless nature of fastbins we need to be careful derefencing pointers to fastbin entries (chunksize(old) in this case) in multithreaded environments. The fix is to add have_lock to the if-condition checks. The rest of the patch only makes code more readable. * malloc/malloc.c (_int_free): Perform sanity check only if we have_lock.
