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. Tested x86_64 and x86 and ulps updated accordingly. * math/libm-test.inc (asinh_test): Use ALL_RM_TEST. (atan_test): Likewise. (atanh_test_data): Use NO_TEST_INLINE for two tests.

2014-03-20PowerPC: optimized strcspn for PPC64/POWER7Adhemerval Zanella8-16/+271
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. The idea is similar as x86_64 uses. For PowerPC some tunings were added, such as unroll loops and align stack memory to table to 16 bytes (so VSX clean can ran without alignment issues).
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). Tested x86_64 and x86. * math/gen-libm-test.pl (generate_testfile): Expect only function name as argument to AUTO_TESTS_* and pass results for all rounding modes to parse_args.

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.

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.
2014-03-18Work around binutils bugs in 2.23 and olderRoland McGrath2-0/+8
binutils versions up through at least 2.23 have some bugs that cause STV_HIDDEN symbols to appear in .dynsyms.
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.)

* Makerules [!subdir] (check-abi): Exit with error status if a test failed.
2014-03-17Test rint and nearbyint with same inputs, in all rounding modes.Joseph Myers2-49/+157
This patch arranges for rint and nearbyint to be tested by libm-test.inc with the same inputs (previously each had some test inputs the other didn't, although there was a lot of overlap as well), and for nearbyint to be tested in all rounding modes where previously it was only tested in round-to-nearest mode. The expected results are the same for each function, except that rint is expected to have "inexact" exceptions for non-integer input and nearbyint is expected not to have those exceptions. Tested x86_64 and x86. * math/libm-test.inc (nearbyint_test_data): Include all tests used for rint. Include results for all rounding modes. (nearbyint_test): Use ALL_RM_TEST. (rint_test_data): Include all tests used for nearbyint.
