* Fix ldbl-128 / ldbl-128ibm lgammal spurious underflow (bug 16400).Joseph Myers2014-01-063-2/+11
| | | | | | | | | | | | | | This patch fixes bug 16400, spurious underflow exceptions for ldbl-128 / ldbl-128ibm lgammal with small positive arguments, by just using -__logl (x) as the result in the problem cases (similar to the previous fix for problems with small negative arguments). Tested powerpc32, and also tested on mips64 that this does not require ulps regeneration for the ldbl-128 case. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgammal_r): Return -__logl (x) for small positive arguments without evaluating a polynomial.

* ia64: add __ prefix to pt_all_user_regs/ia64_fpreg [BZ #762]Mike Frysinger2014-01-065-21/+34
| | | | | | | | | | | | This addresses a long standing collision between userspace headers and kernel headers only on ia64 systems. All other types have a __ prefix in the ptrace headers except these two. Let's finally namespace these. Verified that at least strace still builds after this change, as well as after deleting all the struct hacks it has specifically for ia64.

* ptrace.h: add __ prefix to ptrace_peeksiginfo_argsMike Frysinger2014-01-0611-7/+34
| | | | | | | | | | | | | | | | | | | | | | | | All the other ptrace structures in this file have a __ prefix except this new one. This in turn causes build problems for most packages that try to use ptrace such as strace: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \ -I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \ -MF .deps/process.Tpo -c -o process.o ../../process.c In file included from ../../process.c:63:0: /usr/include/linux/ptrace.h:58:8: error: redefinition of 'struct ptrace_peeksiginfo_args' struct ptrace_peeksiginfo_args { ^ In file included from ../../defs.h:159:0, from ../../process.c:37: /usr/include/sys/ptrace.h:191:8: note: originally defined here struct ptrace_peeksiginfo_args ^ Since this struct was introduced in glibc-2.18, there shouldn't be any real regressions with adding the __ prefix.

* ia64: fix build failure after async tls updatesMike Frysinger2014-01-042-4/+11
| | | | | | | | | | The recent commit 7f507ee17aee720fa423fa38502bc3caa0dd03d7 added a new local variable "offset" to tls_get_addr_tail. This conflicts with the ia64 code which also declares an offset code inline in this func. So have the ia64 code rename its local vars with a prefix that shouldn't collide with anything else in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390).Joseph Myers2014-01-033-1/+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.

* Mark various libm tests with xfail-rounding:ldbl-128ibm.Joseph Myers2014-01-033-1744/+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.
* Fix ldbl-128ibm logl inaccuracy (bug 16386).Joseph Myers2014-01-023-1/+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.
* Fix ldbl-128ibm asinhl inaccuracy (bug 16385).Joseph Myers2014-01-023-2/+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.
* Fix ldbl-128ibm acoshl inaccuracy (bug 16384).Joseph Myers2014-01-023-3/+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.

* Fix return code from getent netgroup when the netgroup is not found (bz #16366)Siddhesh Poyarekar2014-01-023-30/+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.
* Fix infinite loop in nscd when netgroup is empty (bz #16365)Siddhesh Poyarekar2014-01-023-4/+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.
