2014-12-23* string/stpcpy.c (__stpcpy): Rewrite using strlen and memcpy.Richard Earnshaw1-8/+2
2014-12-19 Simplify strncat.Ondřej Bílka1-44/+3
We rewrite strncat to use strnlen and malloc calls which simplifies code an is faster as these functions are better optimized than original code.

2014-11-27Don't use __warn_memset_zero_len for gcc-5.0 or newerSiddhesh Poyarekar1-0/+6
gcc now warns when the arguments to memset may have been accidentally transposed (i.e. length set to zero instead of the byte), so we don't need that bit of the code in glibc headers anymore. Tested on x86_64. Coe generated by gcc 4.8 is identical with or without the patch. I also tested gcc master, which does not result in any new failures. It does fail quite a few FORTIFY_SOURCE tests, but those failures are not due to this patch.
2014-11-26Remove TEST_IFUNC, tests-ifunc and *-ifunc.c tests.Joseph Myers1-3/+2
TEST_IFUNC is only tested in two headers, bench-string.h and test-string.h, after it gets defined by those headers, and it never gets undefined. Thus no defines of TEST_IFUNC are needed, and the *-ifunc.c tests that just define TEST_IFUNC and include other tests are also redundant, as is the code to remove $(tests-ifunc) and $(xtests-ifunc) conditionally from tests and xtests. This patch removes the useless defines and tests of TEST_IFUNC and the associated useless tests and makefile code. It thereby fixes a series of warnings "../string/test-string.h:21:0: warning: "TEST_IFUNC" redefined" where test-string.h defines TEST_IFUNC to empty, other files define it to 1 and this produces warnings. Tested for x86_64. * debug/test-stpcpy_chk-ifunc.c: Remove file. * debug/test-strcpy_chk-ifunc.c: Likewise. * wcsmbs/test-wcschr-ifunc.c: Likewise. * wcsmbs/test-wcscmp-ifunc.c: Likewise. * wcsmbs/test-wcscpy-ifunc.c: Likewise. * wcsmbs/test-wcslen-ifunc.c: Likewise. * wcsmbs/test-wcsrchr-ifunc.c: Likewise. * wcsmbs/test-wmemcmp-ifunc.c: Likewise. * Rules [$(multi-arch) = no] (tests): Do not filter out $(tests-ifunc).

2014-11-26Fix test-strchr.c warnings for wide string testing.Joseph Myers1-3/+5
string/test-strchr.c is used for both wide and narrow string testing, but produces a series of warnings for wide string testing because of hardcoded use of narrow characters in the function check1. This patch fixes that function to use macros abstracting away the wide / narrow string choice, adding a new such macro to handle the string and character constants. Tested for x86_64. * string/test-strchr.c [!WIDE] (L): New macro. [WIDE] (L): Likewise. (check1): Use CHAR instead of char. Use L on string and character constants.

This patch fixes the build of C mempcpy and stpcpy by disabling the redirection to __mempcpy and __stpcpy asm names if NO_MEMPCPY_STPCPY_REDIRECT is defined, and defining that macro in the relevant source files.

2014-11-12Fix locale memmem namespace (bug 17585).Joseph Myers1-3/+6
Locale code, brought in by ISO C functions, calls memmem, which is not an ISO C function. This isn't an ISO C conformance bug, because all mem* names are reserved, but glibc practice is not to rely on that reservation (thus, memmem is only declared in string.h if __USE_GNU even though ISO C would allow it to be declared unconditionally, for example). This patch changes that code to use __memmem. Note: there are uses of memmem elsewhere in glibc that I didn't change, although it may turn out some of those also need to use __memmem. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17585] * string/memmem.c [!_LIBC] (__memmem): Define to memmem. (memmem): Rename to __memmem and define as weak alias of __memmem. Use libc_hidden_weak. (__memmem): Use libc_hidden_def. * include/string.h (__memmem): Declare. Use libc_hidden_proto. * locale/findlocale.c (valid_locale_name): Use __memmem instead of memmem.
2014-11-12Fix tst-strcoll-overflow returning before timeout (BZ #17506)Leonhard Holz1-0/+1
Modifies the test examination in test-skeleton.c so that a test can be successful if it is interrupted or it returns uninterrupted with the expected status. For this both EXPECTED_SIGNAL and EXPECTED_STATUS have to be set, as is done in tst-strcoll-overflow.c.
2014-11-05Modify several tests to use test-skeleton.cArjun Shankar5-10/+25
This patch modifies several test cases to use test-skeleton.c. It was generated by a bash script written for this purpose and thus excludes several other tests which I deemed worth a visual inspection before making the change. I intend to follow up with individual patches to the tests skipped by the script. The script itself resides at http://git.io/WODAmg and should reproduce this very patch when run against master.

2014-10-17strcoll: improve performance by removing the cache (#15884)Leonhard Holz1-318/+26
this is a path that should solve bug 15884. It complains about the performance of strcoll(). It was found out that the runtime of strcoll() is actually bound to strlen which is needed for calculating the size of a cache that was installed to improve the comparison performance. The idea for this patch was that the cache is only useful in rare cases (strings of same length and same first-level-chars) and that it would be better to avoid memory allocation at all. To prove this I wrote a performance test bench-strcoll.c with test data in benchtests-strcoll.tar.gz. Also modifications in benchtests/Makefile and localedata/Makefile are necessary to make it work. After removing the cache the strcoll method showed the predicted behavior (getting slightly faster) in all but the test case for hindi word sorting. This was due the hindi text having much more equal words than the other ones. For equal strings the performance was worse since all comparison levels were run through and from the second level on the cache improved the comparison performance of the original version. Therefore I added a bytewise test via strcmp iff the first level comparison found that both strings did match because in this case it is very likely that equal strings are compared. This solved the problem with the hindi test case and improved the performance of the others.

2014-09-11Move findidx nested functions to top-level.Roland McGrath2-8/+6
2014-07-07PowerPC: optimized memmove for POWER7/PPC64Adhemerval Zanella1-1/+1
This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions.
2014-07-04string/memchr.c: Merge from gnulibWill Newton1-139/+94
Merge most of the gnulib implementation of memchr. The changes that remain are: - copyright header - bp-sym.h removed - reg_char removed - allow MEMCHR to be redefined - non-conforming whitespace changes The merged code fixes a number of -Wundef warnings and also introduces an optimized algorithm. I haven't detected any performance difference in the new code which I believe is down to the quite specific circumstances required to hit it. However the new code is approximately half the size of the old code on AArch64 (which uses generic memchr). ChangeLog: 2014-07-04 Will Newton <will.newton@linaro.org> * string/memchr.c: Merge from gnulib. [_LIBC]: Remove conditionals. (__ptr_t): Remove define. (LONG_MAX_32_BITS): Likewise.

2014-06-07Remove redundant C locale settings.Joseph Myers1-3/+0
Various glibc build / install / test code has C locale settings that are redundant with LC_ALL=C. LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C (explicitly, or through it being in the default environment for running tests) does not need to set LANG=C. LC_ALL=C also takes precedence over LANGUAGE, since 2001-01-02 Ulrich Drepper <drepper@redhat.com> * intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE value is ignored if the selected locale is the C locale. * intl/tst-gettext.c: Set locale for above change. * intl/tst-translit.c: Likewise. and so settings of LANGUAGE=C are also redundant when LC_ALL=C is set. One test also had LC_ALL=C in its -ENV setting, although it's part of the default environment used for tests. This patch removes the redundant settings. It removes a suggestion in install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the Makefile.in target "install" already sets LC_ALL_C so there's no need for the user to set it (and nor should there be any need for the user to set it). If some build machine tool used by "make install" uses a version of libintl predating that 2001 change, and the user has LANGUAGE set, the removal of LANGUAGE=C from the Makefile.in "install" rule could in principle affect the user's installation. However, I don't think we need to be concerned about pre-2001 build tools.

2014-06-04Include LOCPATH in default test environment.Joseph Myers1-5/+0
Tests run using the default $(make-test-out) automatically get GCONV_PATH and LC_ALL set, whether or not those environment variables are actually needed for the individual test. However, they do not get LOCPATH set, meaning that a large number of tests have -ENV settings just to set LOCPATH. This patch moves LOCPATH into the default environment used for all tests, on the principle that like GCONV_PATH any settings needed to use files associated with the newly built library, rather than any old installed files, are appropriate to use by default. A further motivation is that various tests using .sh files also set some combination of LC_ALL, GCONV_PATH and LOCPATH. Preferably .sh files should also use the default environment with any additions required for the individual test. Now, it was suggested in <https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that various Makefile variables used in testing should be derived by composing the -before-env and -after-env variables used when explicit environment settings are required. With such a change, it's also natural for those variables to include the default settings (via some intermediate makefile variable also used in make-test-out). Because some .sh files only set variables that correspond to the default settings, or a subset thereof, and this applies to more of the .sh files once LOCPATH is in the default settings, doing so reduces the size of a revised version of <https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts only needing the (expanded) default settings will not need to receive the separate -before-env and -after-env variables, only the single variable they do at present. So moving LOCPATH into the default settings can reduce churn caused by subsequent patches.

2014-04-07string: Cosmetic cleanup of string functionsWill Newton10-47/+10
Clean up string functions that do not have a version in gnulib on the assumption that glibc is the canonical upstream copy of this code. basename has a copy in gnulib but it is largely written to handle Windows paths so merging it is not really viable. The changes mostly consist of switching to ANSI function prototypes and removing unused includes. As many of these functions do not get built in a typical build due to architecture optimized versions being used instead I built these by hand to verify there were no build warnings and the code was identical. 2014-04-07 Will Newton <will.newton@linaro.org> * string/basename.c [HAVE_CONFIG_H]: Remove #ifdef and and contents.

2014-03-20PowerPC: optimized strpbrk for POWER7Adhemerval Zanella1-10/+6
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.

2014-03-06Enumerate tests with special rules in tests-special variable.Joseph Myers1-1/+4
This patch is a revised and updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>. In order to generate overall summaries of the results of all tests in the glibc testsuite, we need to identify and concatenate the files with the results of individual tests. Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this. However, the normal glibc approach is explicit enumeration of the expected set of files with a given property, rather than all files matching some pattern like that. Furthermore, we would like to be able to mark tests as UNRESOLVED if the file with their results is for some reason missing, and in future we would like to be able to mark tests as UNSUPPORTED if they are disabled for a particular configuration (rather than simply having them missing from the list of tests as at present). Such handling of tests that were not run or did not record results requires an explicit enumeration of tests. For the tests following the default makefile rules, $(tests) (and $(xtests)) provides such an enumeration. Others, however, are added directly as dependencies of the "tests" and "xtests" makefile targets. This patch changes the makefiles to put them in variables tests-special and xtests-special, with appropriate dependencies on the tests listed there then being added centrally. Those variables are used in Rules and so need to be set before Rules is included in a subdirectory makefile, which is often earlier in the makefile than the dependencies were present before. We previously discussed the question of where to include Rules; see the question at <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a discussion in <https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why Rules is included early rather than late in subdirectory makefiles. It was necessary to avoid an indirection through the check-abi target and get the check-abi-* targets for individual libraries into the tests-special variable. The intl/ test $(objpfx)tst-gettext.out, previously built only because of dependencies from other tests, was also added to tests-special for the same reason. The entries in tests-special are the full makefile targets, complete with $(objpfx) and .out. If a future change causes tests to be named consistently with a .out suffix, this can be changed to include just the path relative to $(objpfx), without .out. Tested x86_64, including that the same set of files is generated in the build directory by a build and testsuite run both before and after the patch (except for changes to the elf/tst-null-argv.debug.out.<number> file name), and a build with run-built-tests=no to verify there aren't any more obvious instances of the issue Marcus Shawcroft reported with a previous version in <https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>. * Makefile (tests): Change dependencies to ....

2014-02-26Consistently include Makeconfig after defining subdir.Joseph Myers1-0/+2
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed.

2014-02-21Generate .test-result files for tests with special rules.Joseph Myers1-1/+2
This patch, an updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now proposed for inclusion in glibc, extends the generation of PASS and FAIL status in .test-result files for individual tests to cover tests with their own custom makefile rules. This is just adding $(evaluate-test) calls to all such rules, since tests with multiple commands were previously split into separate tests. Note that the tests the makefiles expect to fail (posix/annexc and conformtest) currently get FAIL listed in the .test-result file, rather than XFAIL; a subsequent patch will introduce a better XFAIL mechanism.

This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

2014-02-14Split up rules for tests that compare output with baselines.Joseph Myers1-5/+3
This patch splits makefile rules that generate a file then run cmp to check the contents of that file into separate rules to generate and compare the file. This simplifies making those tests generate PASS / FAIL results, by removing the need to insert && between commands in the test so that a $(evaluate-test) call is reached. It also avoids the oddity of the .out file being an intermediate file rather than the final result generated, as noted for some of these tests in <https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>. In many cases, the rule to run the program was no longer needed because the default rules for running test programs on the host to generate a .out file sufficed. (I'm not asserting the commands run after this patch are *exactly* the same as before, simply that the rules did nothing special that appeared deliberate or relevant to anything about what the tests were testing. In cases where the rules redirected stderr as well as stdout, I left the existing rule's redirection in place to avoid changing what gets compared with the expected results.) It's clear there is a lot in common between the various -cmp.out rules and it might be possible in future to refactor them into more generic support for the case of comparing test output against a baseline. (Some baselines are *.exp, some *.expect, some directly embedded in the makefiles, and nptl/tst-cleanupx0.expect appears unused.) Tested x86_64. * elf/Makefile ($(objpfx)order.out): Remove rule.

2014-02-13Clean up trivially redundant __USE_MISC conditionals.Joseph Myers2-3/+3
This patch cleans up cases of __USE_MISC that are trivially redundant after the recent substitution of __USE_MISC for __USE_BSD and __USE_SVID: either in constructs such as "defined __USE_MISC || defined __USE_MISC", or else (in the bits/mman.h case) a conditional on __USE_MISC nested inside another __USE_MISC conditional. (The cleanups remaining after this patch are still quite large, but it seems a reasonable piece to separate out.)

2014-02-12Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers5-12/+12
This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

2013-12-23Define __CORRECT_ISO_CPP_STRING_H_PROTO correctly for Clang.Brooks Moses2-4/+12
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.
