* Run tst-ld-sse-use.sh with bash.Joseph Myers2014-09-291-1/+1
| | | | | | | | | | | | | | tst-ld-sse-use.sh is a bash script, not a POSIX shell script, and so needs to be run with $(BASH) not $(SHELL) to avoid errors of the form: ../sysdeps/x86/tst-ld-sse-use.sh: 41: ../sysdeps/x86/tst-ld-sse-use.sh: declare: not found (when /bin/sh is dash). This patch makes that change. Tested for x86_64. * sysdeps/x86/Makefile ($(objpfx)tst-ld-sse-use.out): Run script with $(BASH) not $(SHELL).
* Enhance tst-xmmymm.sh to detect zmm register usage in ld.so (BZ #16194)Siddhesh Poyarekar2014-09-122-6/+6
| | | | | | | | | | | | | | | | 2d63a517e4084ec80403cd9f278690fa8b676cc4 added support to save and restore zmm register in the dynamic linker, but did not enhance test-xmmymm.sh to detect accidental usage of these registers. The patch below adds that check. The script has also been renamed to tst-ld-sse-use.sh. To see the minimal changes, run `git show -M`. [BZ #16194] * sysdeps/x86/tst-xmmymm.sh: Rename file to... * sysdeps/x86/tst-ld-sse-use.sh: ... this. Check for zmm register usage. * sysdeps/x86/Makefile: Adjust.

* Disable x87 inline functions for x86_64 and SSE [BZ #17262]Siddhesh Poyarekar2014-08-131-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Since: commit 409e00bd69b8d8dd74d7327085351d26769ea6fc Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Jan 29 07:51:41 2014 -0800 Disable x87 inline functions for SSE2 math When i386 and x86-64 mathinline.h was merged into a single mathinline.h, "gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse and SSE2 is enabled. It is a regression on x86-64. We should check __SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions. gcc-3.2 is unable to correctly compile x86_64 routines for llrint since it gets redefined. This is because gcc 3.2 does not set __SSE2_MATH__ for x86_64, thus exposing the duplicate definition. The correct fix ought to be to check for both __SSE2_MATH__ and __x86_64__ and enable those bits only when neither are defined. Tested fix with the reproducer for 409e00bd69b8d8dd74d7327085351d26769ea6fc as well as with gcc-3.2.

* Fix pow overflow in non-default rounding modes (bug 16315).Joseph Myers2014-06-231-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16315, bad pow handling of overflow/underflow in non-default rounding modes. Tests of pow are duly converted to ALL_RM_TEST to run all tests in all rounding modes. There are two main issues here. First, various implementations compute a negative result by negating a positive result, but this yields inappropriate overflow / underflow values for directed rounding, so either overflow / underflow results need recomputing in the correct sign, or the relevant overflowing / underflowing operation needs to be made to have a result of the correct sign. Second, the dbl-64 implementation sets FE_TONEAREST internally; in the overflow / underflow case, the result needs recomputing in the original rounding mode. Tested x86_64 and x86 and ulps updated accordingly.

* Add adaptive elision to rwlocksAndi Kleen2014-06-132-2/+114
| | | | | | | | | | | | | | | | | | | This patch relies on the C version of the rwlocks posted earlier. With C rwlocks it is very straight forward to do adaptive elision using TSX. It is based on the infrastructure added earlier for mutexes, but uses its own elision macros. The macros are fairly general purpose and could be used for other elision purposes too. This version is much cleaner than the earlier assembler based version, and in particular implements adaptation which makes it safer. I changed the behavior slightly to not require any changes in the test suite and fully conform to all expected behaviors (generally at the cost of not eliding in various situations). In particular this means the timedlock variants are not elided. Nested trylock aborts.

* Include SSE state in i386 fenv_t (bug 16064).Joseph Myers2014-05-092-0/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16064, i386 fenv_t not including SSE state, using the technique suggested there of storing the state in the existing __eip field of fenv_t to avoid needing to increase the size of fenv_t and add new symbol versions. The included testcase, which previously failed for i386 (but passed for x86_64), illustrates how the previous state was buggy. This patch causes the SSE state to be included *to the extent it is on x86_64*. Where some state should logically be included but isn't for x86_64 (see bug 16068), this patch does not cause it to be included for i386 either. The idea is that any patch fixing that bug should fix it for both x86_64 and i386 at once. Tested i386 and x86_64. (I haven't tested the case of a CPU without SSE2 disabling the test.)

* Enumerate tests with special rules in tests-special variable.Joseph Myers2014-03-061-1/+1

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 ....

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* Disable x87 inline functions for SSE2 mathH.J. Lu2014-01-291-2/+2
| | | | | | | When i386 and x86-64 mathinline.h was merged into a single mathinline.h, "gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse and SSE2 is enabled. It is a regression on x86-64. We should check __SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions.
