* Update timezone code from tzcode 2013i.Joseph Myers2013-12-201-0/+8
| | | | | | | | | | | | | | | | | Now we have Paul's support for version-3 tz files checked in, this patch updates all the code we take (unmodified) from tzcode to version 2013i (which includes the support for generating version-3 tz files where necessary). Tested x86_64. * timezone/checktab.awk: Update from tzcode 2013i. * timezone/private.h: Likewise. * timezone/scheck.c: Likewise. * timezone/tzfile.h: Likewise. * timezone/tzselect.ksh: Likewise. * timezone/zdump.c: Likewise. * timezone/zic.c: Likewise.

* Move various TEST_c_c tests from libm-test.inc to auto-libm-test-inc.Joseph Myers2013-12-201-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves tests of ccos, ccosh, cexp, clog, csqrt, ctan and ctanh to auto-libm-test-in, adding the required support to gen-auto-libm-tests. Other TEST_c_c functions aren't moved for now (although the relevant table entries are put in gen-auto-libm-tests for it to know how to handle them): clog10 because of a known MPC bug causing it to hang for at least some pure imaginary inputs (fixed in SVN, but I'd rather not rely on unreleased versions of MPFR or MPC even if relying on very recent releases); the inverse trig and hyperbolic functions because of known slowness in special cases; and csin / csinh because of observed slowness that I need to investigate and report to the MPC maintainers. Slowness can be bypassed by moving to incremental generation (only for new / changed tests) rather than regenerating the whole of auto-libm-test-out every time, but that needs implementing. (This patch takes the time for running gen-auto-libm-tests from about one second to seven, on my system, which I think is reasonable. The slow functions would make it take several minutes at least, which seems unreasonable.) Tested x86_64 and x86 and ulps updated accordingly. * math/auto-libm-test-in: Add tests of ccos, ccosh, cexp, clog, csqrt, ctan and ctanh. * math/auto-libm-test-out: Regenerated. * math/libm-test.inc (TEST_COND_x86_64): New macro.

* Consolidate code to compute sin and cos from lookup tablesSiddhesh Poyarekar2013-12-201-0/+5
| | | | | | | | | | | This patch consolidates the multiple copies of code that looks up sin and cos of a number from the lookup table and computes the final value, into static functions. This does not have a noticeable performance impact since the functions are inlined by gcc. There is further scope for consolidation in the functions but they cause a more noticable impact on performance (>5%) due to which I have held back on them.
* Remove more redundant computations in s_sin.cSiddhesh Poyarekar2013-12-201-0/+7
| | | | | | | | Removed more redundant computations in the slow paths of the sin and cos functions. The notable change is the passing of the most significant bits of X to the slow functions to check if X is positive so that just the absolute value of x can be passed and the repeated ABS() operation is avoided.
* Remove redundant arguments in reduce_and_computeSiddhesh Poyarekar2013-12-201-0/+5
| | | | | The A and DA arguments in reduce_and_compute are useless and hence have been removed.
* Remove some redundant computations in s_sin.cSiddhesh Poyarekar2013-12-201-0/+9
| | | | | | | | There are multiple points in the code where the absolute value of a number is computed multiple times or is computed even though the value can only be positive. This change removes those redundant computations. Tested on x86_64 to verify that there were no regressions in the testsuite.
* Move tests of cabs and carg from libm-test.inc to auto-libm-test-in.Joseph Myers2013-12-191-0/+10
| | | | | | | | | | | | | | | | | This patch moves tests of cabs and carg to auto-libm-test-in, adding the required support to gen-auto-libm-tests. Tested x86_64 and x86; no ulps updates needed. * math/auto-libm-test-in: Add tests of cabs and carg. * math/auto-libm-test-out: Regenerated. * math/libm-test.inc (cabs_test_data): Use AUTO_TESTS_c_f. (carg_test_data): Likewise. * math/gen-auto-libm-tests.c (func_calc_method): Add value mpc_c_f. (func_calc_desc): Add mpc_c_f union field. (test_functions): Add cabs and carg. (calc_generic_results): Handle mpc_c_f.
* Don't make soft-fp symbols compat symbols for powerpc-nofpu.Joseph Myers2013-12-191-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/powerpc/powerpc32/libgcc-compat.S makes certain symbols that glibc once accidentally reexported from libgcc into compat symbols. Where the exports were purely accidental, this is the right thing to do. However, for powerpc-nofpu the soft-fp symbols are deliberately exported from libc, given public versions in sysdeps/powerpc/nofpu/Versions and used by libm in preference to the libgcc versions that do not support the software exceptions and rounding modes. The libc versions should also be usable by user programs, though normally libgcc gets linked in first (meaning, effectively, that the <fenv.h> functions are broken as regards their expected effects on user arithmetic). A longstanding todo item is to remove the functions in question from libgcc (when built with recent enough glibc) - that is, remove them from static libgcc and make them compat symbols in shared libgcc - so that this works properly (this is one of the items mentioned at <http://gcc.gnu.org/wiki/Software_floating_point> - parts of that page are obviously out of date, but this item still applies). Doing this requires first that the functions are actually available from libc for new links, not just as compat symbols. This patch stops the symbols in question being compat symbols for powerpc-nofpu. The nofpu Versions entries for them are removed (the symbols never were exported at GLIBC_2.3.2, only GLIBC_2.0, because the compat symbols took precedence). Tested powerpc-nofpu. The symbols are no longer compat symbols and libm.so now properly gets undefined references to them (resolved to libc.so) instead of the libgcc copies getting linked into libm as before. * sysdeps/powerpc/powerpc32/libgcc-compat.S [_SOFT_FLOAT || __NO_FPRS__] (__fixdfdi_v_glibc20): Do not define as a macro and a compat symbol. [_SOFT_FLOAT || __NO_FPRS__] (__fixsfdi_v_glibc20): Likewise. [_SOFT_FLOAT || __NO_FPRS__] (__fixunsdfdi_v_glibc20): Likewise. [_SOFT_FLOAT || __NO_FPRS__] (__fixunssfdi_v_glibc20): Likewise.

* Disable libm-test test name beautification for M_* constants.Joseph Myers2013-12-191-0/+4
| | | | | | | | | | | | | | | | | | | | | math/gen-libm-test.pl has code to beautify names of various constants, transforming the source form in libm-test.inc into the version appearing in test names in libm-test-ulps files. This has become decreasingly relevant over time for the M_* constants, first as I changed the test names so only the arguments and not the expected results appeared in them, then as tests have moved to auto-libm-test-* so that automatically generated hex float constants get used instead of M_* in test inputs. This patch removes the beautification for all M_* constants. Tested x86_64 and x86 and ulps updated accordingly. Even the one case where this affected the name in the ulps files will disappear once complex function tests are moved to auto-libm-test-*. * math/gen-libm-test.pl (%beautify): Remove M_* constants. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
* Fix x86/x86_64 expm1 inaccuracy near 0 in directed rounding modes (bug 16293).Joseph Myers2013-12-191-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 16293 is inaccuracy of x86/x86_64 versions of expm1, near 0 in directed rounding modes, that arises from frndint rounding the exponent to 1 or -1 instead of 0, resulting in large cancellation error. This inaccuracy in turn affects other functions such as sinh that use expm1. This patch fixes the problem by setting round-to-nearest mode temporarily around the affected calls to frndint. I don't think this is needed for other uses of frndint, such as in exp itself, as only for expm1 is the cancellation error significant. Tested x86_64 and x86 and ulps updated accordingly. * sysdeps/i386/fpu/e_expl.S (IEEE754_EXPL) [USE_AS_EXPM1L]: Set round-to-nearest mode when using frndint. * sysdeps/i386/fpu/s_expm1.S (__expm1): Likewise. * sysdeps/i386/fpu/s_expm1f.S (__expm1f): Likewise. * sysdeps/x86_64/fpu/e_expl.S (IEEE754_EXPL) [USE_AS_EXPM1L]: Likewise. * math/auto-libm-test-in: Add more tests of expm1.

* Add _DEFAULT_SOURCE feature test macro.Joseph Myers2013-12-191-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a feature test macro _DEFAULT_SOURCE to enable the default set of header declarations. The intention is: if _DEFAULT_SOURCE is not used there is no change to the set of __USE_* macros glibc defines; if it's used on its own, and without compiler options such as -std=c99 that define __STRICT_ANSI__, again, there is no change; if it's used together with the macros it approximately (i.e., apart from __USE_POSIX_IMPLICITLY) implies (-D_BSD_SOURCE -D_SVID_SOURCE -D_POSIX_C_SOURCE=200809L), again, there is no change. Otherwise, it causes the relevant features to be enabled, even if __STRICT_ANSI__, or another feature test macro, would cause them to be disabled. This macro deliberately bundles the POSIX.1-2008 (non-X/Open) functionality with the BSD/SVID/"misc" functionality, rather than defining a macro that gives just the latter, as many of the header cleanups resulting from removing _BSD_SOURCE and _SVID_SOURCE support are only possible when BSD/SVID/"misc" is always bundled with POSIX.1-2008. Tested x86_64. * include/features.h: Update comment documenting feature test macros. Mention _DEFAULT_SOURCE in comment. [_GNU_SOURCE] (_DEFAULT_SOURCE): Undefine and redefine. [_DEFAULT_SOURCE]: Undefine and redefine _DEFAULT_SOURCE, _BSD_SOURCE and _SVID_SOURCE.

* Stop partial menu generation in INSTALL fileAllan McRae2013-12-191-0/+5
| | | | | | | | | | The commit d136c6dc resulted in menu text for the "Top" node being added to the INSTALL file on regeneration. As the full menu is not displayed in the plain text file anyway, suppress the menu section completely to avoid the additional text. Also regenerate the INSTALL file to commit a small formatting change introduced in the same commit.

* Add error reporting (via errno) to getauxval().Brooks Moses2013-12-181-0/+11
| | | | | | | | | | | | [BZ 15846] As discussed in the recent thread on my $EXEC_ORIGIN patch and in BZ 15846, getauxval() presently has no unambiguous way of reporting an error condition. It currently returns zero on error, but this may also be a valid result for some auxv entries. As there is no clear invalid result for all current and future auxv entries, this patch sets errno (following a suggestion in the BZ entry). This version of the patch also adds documentation and tests for the value-not-found conditions in getauxval().
* Move tests of jn and yn from libm-test.inc to auto-libm-test-in.Joseph Myers2013-12-181-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | This patch moves tests of jn and yn to auto-libm-test-in, adding the required support for gen-auto-libm-tests (and adding a missing assertion there and fixing logic that was broken for functions with integer arguments). Tested x86_64 and x86 and ulps updated accordingly. * math/auto-libm-test-in: Add tests of jn and yn. * math/auto-libm-test-out: Regenerated. * math/libm-test.inc (jn_test_data): Use AUTO_TESTS_if_f. (yn_test_data): Likewise. * math/gen-auto-libm-tests.c (func_calc_method): Add value mpfr_if_f. (func_calc_desc): Add mpfr_if_f union field. (FUNC_mpfr_if_f): New macro.

| | | | | | | | | | My recent changes that added libm_hidden_proto / libm_hidden_def for fegetround had the side effect of removing the need for a localplt.data entry for fegetround for powerpc-nofpu. This patch removes that entry. Tested powerpc-nofpu. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/nptl/localplt.data: Don't expect fegetround reference in libm.so.

* Fix ldbl-128 logl for subnormals (bug 16338).Joseph Myers2013-12-181-0/+11
| | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16338, ldbl-128 logl not handling subnormals (with consequent inaccuracy for lgammal as well). The fix is simply to use __frexpl when determining the exponent, as done already in log2l and log10l. Given the lack of testing of small arguments to any of the log* functions, appropriate tests are added for all of them. Tested x86_64 and x86 and ulps updated accordingly, and spot tests also run for mips64 to confirm the ldbl-128 fix. Note that while this fixes lgammal inaccuracy for small positive arguments, I suspect that there will still be problems with spurious underflows in that case. * sysdeps/ieee754/ldbl-128/e_logl.c (__ieee754_logl): Use __frexpl to determine exponent and adjust argument to have exponent of -1. * math/auto-libm-test-in: Add more tests of log, log10, log1p and log2. * math/auto-libm-test-out: Regenerated. * sysdeps/x86_64/fpu/libm-test-ulps: Update.

* Add --enable-maintainer-mode configure optionAllan McRae2013-12-161-0/+5
| | | | | | | | | Autoconf is tested for and run if needed only when --enable-maintainer-mode is used on configure. This results in the autom4te.cache directory only being written in the source directory during configure if automatic autoconf usage is requested. Fixes BZ #14120.
