* S390: Fix unwind in 32-bit _mcountIlya Leoshkevich2018-08-102-2/+11
| | | | | | | | | | * Fix CFI offset for %r14. * Fix unwound value of %r15 being off by 128 bytes. ChangeLog: * sysdeps/s390/s390-32/s390-mcount.S (_mcount): Fix unwind.
* S390: Implement 64-bit __fentry__Ilya Leoshkevich2018-08-105-57/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Since __fentry__ is almost the same as _mcount, reuse the code by #including it twice with different #defines around. * Remove LA usages - they are needed in 31-bit mode to clear the top bit, but in 64-bit they appear to do nothing. * Add CFI rule for the nonstandard return register. This rule applies to the current function (binutils generates a new CIE - see gas/dw2gencfi.c:select_cie_for_fde()), so it is not necessary to put __fentry__ into a new file. * Fix CFI offset for %r14. * Add CFI rule for %r0. * Fix unwound value of %r15 being off by 244 bytes. * Unwinding in __fentry__@plt does not work, no plan to fix it - it would require asking linker to generate CFI for return address in %r0. From functional perspective keeping it broken is fine, since the callee did not have a chance to do anything yet. From convenience perspective it would be possible to enhance GDB in the future to treat __fentry__@plt in a special way. * Fix whitespace. * Fix offsets in comments, which were copied from 32-bit code. * 32-bit version will not be implemented, since it's not compatible with the corresponding PLT stubs: they assume %r12 points to GOT, which is not the case for gcc-emitted __fentry__ stub, which runs before the prolog. This patch adds the runtime support in glibc for the -mfentry gcc feature introduced in [1] and [2].

* Move __fentry__ version definition to sysdeps/{i386,x86_64}Ilya Leoshkevich2018-08-104-3/+12
| | | | | | | | | | | | | | __fentry__ symbol is currently not defined for other architectures. Attempts to introduce it cause abicheck to fail, because it will be available since 2.29 earliest, and not 2.13, which is the case for Intel. With the new code, abicheck passes for i686-linux-gnu, x86_64-linux-gnu and x86_64-linux-gnu32 triples. ChangeLog: * stdlib/Versions: Remove __fentry__. * sysdeps/i386/Versions: Add __fentry__. * sysdeps/x86_64/Versions: Add __fentry__.

* Replace gen-libm-test.pl with gen-libm-test.py.Joseph Myers2018-08-0910-875/+651
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following the recent discussion of using Python instead of Perl and Awk for glibc build / test, this patch replaces gen-libm-test.pl with a new gen-libm-test.py script. This script should work with all Python versions supported by glibc (tested by hand with Python 2.7, tested in the build system with Python 3.5; configure prefers Python 3 if available). This script is designed to give identical output to gen-libm-test.pl for ease of verification of the change, except for generated comments referring to .py instead of .pl. (That is, identical for actual inputs passed to the script, not necessarily for all possible input; for example, this version more precisely follows the C standard syntax for floating-point constants when deciding when to add LIT macro calls.) In one place a comment notes that the generation of NON_FINITE flags is replicating a bug in the Perl script to assist in such comparisons (with the expectation that this bug can then be separately fixed in the Python script later). Tested for x86_64, including comparison of generated files (and hand testing of the case of generating a sorted libm-test-ulps file, which isn't covered by normal "make check"). I'd expect to follow this up by extending the new script to produce the ulps tables for the manual as well (replacing manual/libm-err-tab.pl, so that then we just have one ulps file parser) - at which point the manual build would depend on both Perl and Python (eliminating the Perl dependency would require someone to rewrite summary.pl in Python, and that would only eliminate the *direct* Perl dependency; current makeinfo is written in Perl so there would still be an indirect dependency). I think install.texi is more or less equally out-of-date regarding Perl and Python uses before and after this patch, so I don't think this patch depends on my patch <https://sourceware.org/ml/libc-alpha/2018-08/msg00133.html> to update install.texi regarding such uses (pending review). * math/gen-libm-test.py: New file. * math/gen-libm-test.pl: Remove. * math/Makefile [$(PERL) != no]: Change condition to [PYTHON].

| | | | | | | | | | | | | | When libm tests were split into separate per-function .inc files, a comment relating to the nexttoward tests ended up at the end of libm-test-nextdown.inc (because the split was based on starting each function's tests with the <function>_test_data definition, which failed to allow for comments before such definitions).

* Consistently terminate libm-test-*.inc TEST lines with commas.Joseph Myers2018-08-034-22/+29
| | | | | | | | | | | | | | | | | Some TEST_* lines in libm-test-*.inc end with semicolons not commas. This works at present because gen-libm-test.pl ignores whatever comes after the TEST_* call, but is logically wrong (since the TEST_* calls generate array elements, not statements) and the Python replacement for gen-libm-test.pl that I'm working on is stricter about the syntax here. This patch fixes the lines in question to use commas like most such lines already do.

| | | | | | | | | | | | Looking at the benchtests, both strstr and strcasestr spend a lot of time in a slow initialization loop handling one character per iteration. This can be simplified and use the much faster strlen/strnlen/strchr/memcmp. Read ahead a few cachelines to reduce the number of strnlen calls, which improves performance by ~3-4%.

* Do not define various fenv.h macros for MIPS soft-float (bug 23479).Joseph Myers2018-08-025-16/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MIPS soft-float glibc does not support floating-point exceptions and rounding modes, and uses a different ABI from hard-float so a soft-float compilation cannot use a glibc that does support floating-point exceptions and rounding modes. Thus, bits/fenv.h should not, when compiling for soft-float, define macros for the unsupported features. This patch changes it accordingly to define those macros only for hard-float. None of the exception macros are defined for soft-float, with FE_ALL_EXCEPT defined to 0 in that case, and only FE_TONEAREST is defined of the rounding-mode macros, and FE_NOMASK_ENV is not defined; this is consistent with how architectures lacking exception and rounding mode support generally define things in this header. As well as making the header more correct for this case, this also means the generic math_private.h optimizations for this case automatically apply (inlining libm-internal fenv.h function calls that are trivial when exceptions and rounding modes are not supported). The mips64 sfp-machine.h then needs similar changes to disable more of the exception and rounding mode handling for soft-float. (The mips32 sfp-machine.h is already used only for soft-float, has no integration with hardware exceptions or rounding modes and so needs no changes.) Existing binaries might use the old FE_NOMASK_ENV value as an argument to fesetenv / feupdateenv and expect an error for it (given that it was defined in a header that also defined FE_ALL_EXCEPT to a nonzero value). To preserve that error, wrappers for the fallback fesetenv and feupdateenv are created in sysdeps/mips/nofpu/. Tested for mips64 (hard-float and soft-float, all three ABIs).

* Fix math/test-misc.c for undefined fenv.h macros.Joseph Myers2018-08-012-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | math/test-misc.c contains some code that uses fenv.h macros FE_UNDERFLOW, FE_OVERFLOW and FE_UPWARD without being conditional on those macros being defined. That would normally break the build for configurations (typically soft-float) not defining those macros. However, the code in question is inside LDBL_MANT_DIG > DBL_MANT_DIG conditionals. And, while we have configurations lacking rounding mode and exception support where LDBL_MANT_DIG > DBL_MANT_DIG (soft-float MIPS64 and RISC-V), those configurations currently define the fenv.h macros in question even for soft-float. There may be some case for defining those macros in cases where a soft-float compilation could use a hard-float libm (where both soft-float and hard-float can use the same ABI, as on ARM and RISC-V, for example). But MIPS is not such a case - the hard-float and soft-float ABIs are incompatible - and thus I am testing a patch to stop defining those macros for soft-float MIPS (motivated by reducing the extent to which architectures need their own definitions of math-tests.h macros - if lack of rounding mode / exception support can be determined by the lack of macros in fenv.h, that avoids the need for math-tests.h to declare that lack as well). Introducing a case of LDBL_MANT_DIG > DBL_MANT_DIG without these macros defined shows up the problem with math/test-misc.c. This patch then fixes that problem by adding appropriate conditionals. Tested for MIPS64 in conjunction with changes to stop defining the macros in question in bits/fenv.h for soft-float. * math/test-misc.c (do_test) [LDBL_MANT_DIG > DBL_MANT_DIG]: Make code using FE_UNDERFLOW conditional on [FE_UNDERFLOW], code using FE_OVERFLOW conditional on [FE_OVERFLOW] and code using FE_UPWARD conditional on [FE_UPWARD].

| | | | | | | | | | | | | | | | | | | | | | The math-tests.h header has many different macros and groups of macros, defined using #ifndef in the generic version which is included by architecture versions with #include_next after possibly defining non-default versions of some of those macros. This use of #ifndef is contrary to our normal typo-proof conventions for macro definitions. This patch moves one of the macros, SNAN_TESTS_TYPE_CAST, out to its own sysdeps header, to follow those typo-proof conventions more closely. Tested with build-many-glibcs.py. 2018-08-01 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/math-tests-snan-cast.h: New file. * sysdeps/powerpc/math-tests-snan-cast.h: Likewise. * sysdeps/generic/math-tests.h: Include <math-tests-snan-cast.h>.

* hurd: Fix exec usage of mach_setup_threadSamuel Thibault2018-08-018-11/+41
| | | | | | | | | | | | | | | | Exec needs that mach_setup_thread does *not* set up TLS since it works on another task, so we have to split this into mach_setup_tls. * mach/mach.h (__mach_setup_tls, mach_setup_tls): Add prototypes. * mach/setup-thread.c (__mach_setup_thread): Move TLS setup to...
