2014-03-27Fix x86/x86_64 expl/exp10l spurious underflows (bug 16348).Joseph Myers6-9/+715
This patch fixes bug 16348, spurious underflows from x86/x86_64 expl on arguments close to 0. These implementations effectively use expm1 (on the fractional part of the argument) internally, so resulting in spurious underflows when the result is very close to 1. For arguments small enough that the round-to-nearest correct result is 1, this patch uses 1+x instead. These implementations are also used for exp10l and so the patch fixes similar issues there (the 0x1p-67 threshold being small enough to be correct for exp10l as well as expl). But because of spurious underflows in other exp10 implementations (bug 16560), the tests aren't added for exp10 at this point - they can be added when the other exp10 parts of that bug are fixed. Tested x86_64 and x86; no ulps updates needed. [BZ #16348] * sysdeps/i386/fpu/e_expl.S (IEEE754_EXPL) [!USE_AS_EXPM1L]: Use 1+x for argument with exponent below -67. * sysdeps/x86_64/fpu/e_expl.S (IEEE754_EXPL) [!USE_AS_EXPM1L]: Likewise. * math/auto-libm-test-in: Add more tests of exp. * math/auto-libm-test-out: Regenerated.
2014-03-27Return NULL for wildcard values in getnetgrent from nscd (BZ #16759)Siddhesh Poyarekar3-4/+17
getnetgrent is supposed to return NULL for values that are wildcards in the (host, user, domain) triplet. This works correctly with nscd disabled, but with it enabled, it returns a blank ("") instead of a NULL. This is easily seen with the output of `getent netgroup foonet` for a netgroup foonet defined as follows in /etc/netgroup: foonet (,foo,) The output with nscd disabled is: foonet ( ,foo,) while with nscd enabled, it is: foonet (,foo,) The extra space with nscd disabled is due to the fact that `getent netgroup` adds it if the return value from getnetgrent is NULL for either host or user.
2014-03-27Avoid overlapping addresses to stpcpy calls in nscd (BZ #16760)Siddhesh Poyarekar3-7/+17
Calls to stpcpy from nscd netgroups code will have overlapping source and destination when all three values in the returned triplet are non-NULL and in the expected (host,user,domain) order. This is seen in valgrind as: ==3181== Source and destination overlap in stpcpy(0x19973b48, 0x19973b48) ==3181== at 0x4C2F30A: stpcpy (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==3181== by 0x12567A: addgetnetgrentX (string3.h:111) ==3181== by 0x12722D: addgetnetgrent (netgroupcache.c:665) ==3181== by 0x11114C: nscd_run_worker (connections.c:1338) ==3181== by 0x4E3C102: start_thread (pthread_create.c:309) ==3181== by 0x59B81AC: clone (clone.S:111) ==3181== Fix this by using memmove instead of stpcpy.
2014-03-26Fix dwarf2 unwinding through futex functions.Andi Kleen3-336/+53
When profiling programs with lock problems with perf record -g dwarf, libunwind can currently not backtrace through the futex and unlock functions in pthread. This is because they use out of line sections, and those are not correctly described in dwarf2 (I believe needs dwarf3 or 4). This patch first removes the out of line sections. They only save a single jump, but cause a lot of pain. Then it converts the now inline lock code to use the now standard gas .cfi_* commands. With these changes libunwind/perf can backtrace through the futex functions now. Longer term it would be likely better to just use C futex() functions on x86 like all the other architectures. This would clean the code up even more.
2014-03-27Fix nscd lookup for innetgr when netgroup has wildcards (BZ #16758)Siddhesh Poyarekar3-4/+14
nscd works correctly when the request in innetgr is a wildcard, i.e. when one or more of host, user or domain parameters is NULL. However, it does not work when the the triplet in the netgroup definition has a wildcard. This is easy to reproduce for a triplet defined as follows: foonet (,foo,) Here, an innetgr call that looks like this: innetgr ("foonet", "foohost", "foo", NULL); should succeed and so should: innetgr ("foonet", NULL, "foo", "foodomain"); It does succeed with nscd disabled, but not with nscd enabled. This fix adds this additional check for all three parts of the triplet so that it gives the correct result. [BZ #16758] * nscd/netgroupcache.c (addinnetgrX): Succeed if triplet has blank values.

Bug 16198 is x86_64 fegetenv wrongly masking exceptions for which traps are enabled, because that's a side-effect of the fnstenv instruction. This patch fixes it to use fldenv immediately after fnstenv, like the i386 version. Tested x86_64 and x86.

2014-03-25Relax gen-auto-libm-tests may-underflow rules, test log1p in all rounding modes.Joseph Myers8-299/+367
gen-auto-libm-tests presently allows but does not require underflow exceptions for results with magnitude in the range (greatest subnormal, least normal]. In some cases, the magnitude of the exact result is very slightly above the least normal, but rounding in the implementation results in it effectively computing an infinite-precision result that is slightly below the least normal, so raising an underflow exception. This is in accordance with the documented accuracy goals, but results in testsuite failures. This patch changes the logic to allow underflows when the mathematical result is up to 0.5ulp above the least normal (so in any case where the round-to-nearest result is the least normal). Ideally underflows in all these cases would be accepted only when an underflow with the actual result is consistent with the rounding mode (in FE_TOWARDZERO mode, a return value of the least normal implies that the infinite-precision result did not underflow so there should be no underflow exception, for example), so as to match the documented goals more precisely - whereas at present the tests for exceptions are completely independent of the tests of the returned values. (The same applies to overflow exceptions as well - they too should be checked for consistency with the result, as in FE_TOWARDZERO mode a result 1ulp below the largest finite value should be inconsistent with an overflow exception and cause a failure with overflow rather than simply being considered a 1ulp error when overflow is expected.) But the present patch at least deals with the cases causing spurious failures so that (a) certain existing tests no longer need to be marked as having spurious exceptions (such markings in auto-libm-test-in end up applying to more cases than just those they are needed for) and (b) log1p can be tested in all rounding modes without introducing more such failures. This patch duly moves tests of log1p to ALL_RM_TEST. Tested x86_64 and x86 and ulps updated accordingly.

2014-03-24Fix use of half-initialized result in getaddrinfo when using nscd (bug 16743)Andreas Schwab3-1/+16
This fixes a bug in the way the results from __nscd_getai are collected: for every returned result a new entry is first added to the gaih_addrtuple list, but if that result doesn't match the request this entry remains uninitialized. So for this non-matching result an extra result with uninitialized content is returned.

2014-03-24Fix dbl-64 exp overflow/underflow in non-default rounding modes (bug 16284).Joseph Myers8-557/+954
The dbl-64 version of exp needs round-to-nearest mode for its internal computations, but that has the consequence of inappropriate overflowing and underflowing results in other rounding modes. This patch fixes this by recomputing the relevant results in cases where the round-to-nearest result overflows to infinity or underflows to zero (most of the diffs are actually just consequent reindentation). Tests are enabled in all rounding modes for complex functions using exp - but not for cexp because it turns out there are bugs causing spurious underflows for cexp for some tests, which will need to be fixed separately (I suspect ccos ccosh csin csinh ctan ctanh have similar bugs, just not shown by the present set of test inputs). Tested x86_64 and x86 and ulps updated accordingly.

2014-03-21Fix -Wundef warnings for _ABI* on MIPS.Joseph Myers4-0/+9
This patch fixes -Wundef warnings related to the _ABI* macros on MIPS. GCC predefines only the _ABI* macro related to the ABI actually in use, meaning that a conditional such as "#if _MIPS_SIM == _ABI64" is true only for the ABI in question (all the macros are nonzero), but produces a -Wundef warning for the other ABIs. The normal approach to using these macros is to include <sgidefs.h>, which ensures that all three _ABI* macros are defined rather than just one; this patch does so in the places that caused warnings (the bulk of the warnings arising from <bits/wordsize.h>). Tested that the warnings are fixed. * sysdeps/mips/bits/wordsize.h: Include <sgidefs.h>. * sysdeps/unix/sysv/linux/mips/getrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/mips/setrlimit64.c: Likewise.
2014-03-21Fix log (1) in round-downward mode (bug 16731).Joseph Myers12-9/+88
According to ISO C Annex F, log (1) should be +0 in all rounding modes, but some implementations in glibc wrongly return -0 in round-downward mode (mapping to log1p (x - 1) is problematic because 1 - 1 is -0 in round-downward mode, and log1p (-0) is -0). This patch fixes this. (It helps with some implementations of other functions such as acosh, log2 and log10 that call out to log, but not enough to enable all-rounding-modes testing for those functions without further fixes to other implementations of them.) Tested x86_64 and x86 and ulps updated accordingly, and did spot tests for mips64 for the ldbl-128 fix, and i586 for the sysdeps/i386/fpu implementations shadowed by those in sysdeps/i386/i686/fpu.

2014-03-20PowerPC: optimized strpbrk for POWER7Adhemerval Zanella8-11/+282
This patch add an optimized strpbrk for POWER7 by using a different algorithm than default implementation: it constructs a table based on the 'accept' argument and use this table to check for any occurance on the input string. The idea is similar as x86_64 uses. For PowerPC some tunings were added, such as unroll loops and memory clear using VSX instructions.
2014-03-21Test most libm functions in all rounding modes.Joseph Myers4-74/+1222
This patch makes libm-test.inc tests of most functions use ALL_RM_TEST unless there was some reason to defer that change for a particular function. I started out planning to defer the change for pow (bug 16315), cexp / ccos / ccosh / csin / csinh (likely fallout from exp, bug 16284) and cpow (exact expectations for signs of exact zero results not wanted). Testing on x86_64 and x86 showed additional failures for acosh, cacos, catan, catanh, clog, clog10, jn, log, log10, log1p, log2, tgamma, yn, so making the change for those functions was deferred as well, pending investigation to show which of these represent distinct bugs (some such bugs may already be filed) and appropriate fixing / XFAILing. Failures include wrong signs of zero results, errors slightly above the 9ulp bound (in such cases it may make sense for functions to set round-to-nearest internally to reduce error accumulation), large errors and incorrect overflow/underflow for the rounding mode (with consequent missing errno settings in some cases). It's possible some could be issues with test expectations, though I didn't notice any that were obviously like that (I added NO_TEST_INLINE for cases that were failing for ildoubl on x86 and where it seemed reasonable for them to fail for the fast-math inlines). There may of course be failures on other architectures for functions that didn't fail on x86_64 or x86, in which case the usual rule applies: file a bug (preferably identifying the underlying problem function, in cases where function A calls function B and a problem with function B may present in the test results for function A) if not already in Bugzilla then fix or XFAIL.

This patch add a optimized strcspn for POWER7 by using a different algorithm than default implementation: it constructs a table based on the 'accept' argument and use this table to check for any occurance on the input string.

2014-03-20Make libm-test support ALL_RM_TEST with AUTO_TESTS_*.Joseph Myers3-1035/+361
This patch continues improvements to all-rounding-mode libm testing by making testing with ALL_RM_TEST support test results from auto-libm-test-out. gen-libm-test.pl is adapted to generate appropriate output with results for each rounding mode, with AUTO_TESTS_* calls no longer specifying a rounding mode. Where there were separate functions in libm-test.inc to test a function in each rounding mode, using AUTO_TESTS_* to list the tests for each rounding mode, those are converted to using ALL_RM_TEST (so generally this patch doesn't change the sets of tests run in each rounding mode, except that in various cases special-case tests given directly in libm-test.inc were previously run only for round-to-nearest, and now are run for all rounding modes).

2014-03-19Use ALL_RM_TEST for more libm tests.Joseph Myers2-32/+17
Continuing the move to using ALL_RM_TEST for tests in libm-test.inc, this patch converts the tests of fdim, ldexp and scalb. fdim and scalb are cases where tests could depend on the rounding mode though none of the present test inputs do; ldexp is such a case where the function is equivalent to scalbn (for binary floating point) and the tests used were a subset of those for scalbn, so this patch makes ldexp testing use the scalbn tests, as done for other cases of libm function aliases. Tested x86_64 and x86. * math/libm-test.inc (fdim_test): Use ALL_RM_TEST. (ldexp_test_data): Remove. (ldexp_test): Move to after scalbn_test. Use ALL_RM_TEST with scalbn_test_data. (scalb_test): Use ALL_RM_TEST.

2014-03-19Fix __ASSUME_PREADV and __ASSUME_PWRITEV for Alpha and MicroBlaze (bug 16649).Joseph Myers4-3/+22
Reviewing (for all architectures, with a baseline kernel version of 2.6.32) the kernel support for features for which __ASSUME_* macros would be affected by a move to 2.6.32 as minimum kernel version showed up that __ASSUME_PREADV and __ASSUME_PWRITEV were wrongly defined for MicroBlaze (despite the corresponding syscall table entries not being wired up in the kernel) and Alpha for 2.6.30 and above (although the support on Alpha was added in 2.6.33). This patch makes the kernel-features.h files undefine those macros for appropriate versions. [BZ #16649] * sysdeps/unix/sysv/linux/alpha/kernel-features.h [__LINUX_KERNEL_VERSION < 0x020621] (__ASSUME_PREADV): Undefine. [__LINUX_KERNEL_VERSION < 0x020621] (__ASSUME_PWRITEV): Likewise. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_PREADV): Undefine. (__ASSUME_PWRITEV): Likewise.

2014-03-18Add stardard definition on conform processingAdhemerval Zanella2-2/+7
This patch adds the -std=c99 option when preprocessing the data files from the conform testcases. It fixes an issue where the compiler may split the 'macro bool' defition from stdbool.h-data in two lines and thus breaking the conform script.
2014-03-18Test scalbn and scalbln in all rounding modes, add more tests of negative ↵Joseph Myers3-47/+98
arguments. Continuing the move to systematically testing libm functions in all rounding modes with ALL_RM_TEST, this patch converts the tests of scalbn and scalbln to use that macro. Those tests include cases of underflow and overflow, meaning the expected results depend on the rounding mode. For convenience in writing such tests manually, the patch adds the notation plus_oflow, minus_oflow, plus_uflow and minus_uflow for overflowing / underflowing results of each sign appropriate to the rounding mode being used, and gen-libm-test.pl is made to substitute in the appropriate values. The tests of underflow and overflow are extended to include negative arguments to provide better coverage (otherwise minus_oflow and minus_uflow wouldn't have been used at all). (A subsequent patch will make ldexp use the scalbn tests, as those functions are equivalent for binary floating point.) Tested x86_64 and x86. * math/gen-libm-test.pl (parse_args): Handle plus_oflow, minus_oflow, plus_uflow and minus_uflow in expected results. * math/libm-test.inc (scalbn_test_data): Add more tests of negative arguments. Use plus_oflow, minus_oflow, plus_uflow and minus_uflow. (scalbn_test): Use ALL_RM_TEST. (scalbln_test_data): Add more tests of negative arguments. Use plus_oflow, minus_oflow, plus_uflow and minus_uflow. (scalbln_test): Use ALL_RM_TEST.

2014-03-18misc/sys/xattr.h: guard against linux uapi header inclusionSerge Hallyn1-0/+2
If the glibc xattr.h header is included after the uapi header, compilation fails due to an enum re-using a #define from the uapi header. Protect against this by guarding the define and enum inclusions against each other. (A corresponding kernel patch has been sent here: http://lkml.org/lkml/2014/3/7/331 ) (See https://lists.debian.org/debian-glibc/2014/03/msg00029.html and https://sourceware.org/glibc/wiki/Synchronizing_Headers for more information.)
