* S390: Save and restore r12 in TLS_IE macro.Stefan Liebler2017-06-271-0/+5
| | | | | | | | | | | | | | | | | | | | | The testcases elf/tst-tls1-static and elf/tst-tls2-static are failing on s390 if gcc is configured with --enable-default-pie. According to binutils, there are only four valid cases for IE -> LE transition: lg %rx,(0,%ry) -> sllg %rx,%ry,0 lg %rx,(%ry,0) -> sllg %rx,%ry,0 lg %rx,(%ry,%r12) -> sllg %rx,%ry,0 lg %rx,(%r12,%ry) -> sllg %rx,%ry,0 Thus I've adjusted the TLS_IE macro in s390 tls-macros.h files in PIC case in order to use r12 for the address of global offset table. The adjusted macro definition is not used if gcc is not configured with --enable-default-pie. ChangeLog: * sysdeps/s390/s390-32/tls-macros.h (TLS_IE): Use r12 for GOT address. * sysdeps/s390/s390-64/tls-macros.h (TLS_IE): Likewise.
* resolv: Avoid timeouts in test-resolv-res-init, test-resolv-res_init-threadFlorian Weimer2017-06-271-0/+7
| | | | | | | Some Linux kernels have very aggressive ICMP rate limiting on the loopback interface. This commit introduces a minimal echoing DNS server inside the network namespace, so that there is no need for ICMP error messages anymore.
* resolv: Call _res_hconf_init from __res_vinitFlorian Weimer2017-06-271-0/+19
| | | | | | | | Many callers of __res_maybe_init also call _res_hconf_init. Additional calls to the latter do not hurt because the function does its work only once. (/etc/hosts.conf is not reloaded or even checked for changes.) This means that we can simplify the code by calling _res_hconf_init directly from __res_vinit.
* Add float128 support for ia64.Joseph Myers2017-06-261-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables float128 support for ia64, so that all the configurations where GCC supports _Float128 / __float128 as an ABI-distinct type now have glibc support as well. bits/floatn.h declares the support to be available for GCC 4.4 and later, which is when the libgcc support was added. The removal of sysdeps/ia64/fpu/k_rem_pio2.c is because the generic k_rem_pio2.c defines a function required by the float128 code. Tested (compilation only) with build-many-glibcs.py for ia64 (GCC 6 and GCC 7). Given how long it is since libm-test-ulps has been updated for ia64, I think truncating the file and regenerating it from scratch would be a good idea when doing a regeneration to add float128 ulps. I expect various ia64 libm issues (at least some already filed in Bugzilla) to result in test failures even after ulps regeneration, but hopefully the float128 code will pass tests as it's the same as used on other architectures. * sysdeps/ia64/Implies: Add ieee754/float128. * sysdeps/ia64/bits/floatn.h: New file. * sysdeps/ia64/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on ia64. * sysdeps/ia64/Makefile [$(subdir) = math] (CPPFLAGS): Append to Makefile variable. * sysdeps/ia64/fpu/e_sqrtf128.c: New file. * sysdeps/ia64/fpu/k_rem_pio2.c: Remove file. * sysdeps/ia64/fpu/sfp-machine.h: New file.

* Rename struct ucontext tag (bug 21457).Joseph Myers2017-06-261-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed. Tested for x86_64, and with build-many-glibcs.py.

* Add float128 support for x86_64, x86.Joseph Myers2017-06-261-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables float128 support for x86_64 and x86. All GCC versions that can build glibc provide the required support, but since GCC 6 and before don't provide __builtin_nanq / __builtin_nansq, sNaN tests and some tests of NaN payloads need to be disabled with such compilers (this does not affect the generated glibc binaries at all, just the tests). bits/floatn.h declares float128 support to be available for GCC versions that provide the required libgcc support (4.3 for x86_64, 4.4 for i386 GNU/Linux, 4.5 for i386 GNU/Hurd); compilation-only support was present some time before then, but not really useful without the libgcc functions. fenv_private.h needed updating to avoid trying to put _Float128 values in registers. I make no assertion of optimality of the math_opt_barrier / math_force_eval definitions for this case; they are simply intended to be sufficient to work correctly. Tested for x86_64 and x86, with GCC 7 and GCC 6. (Testing for x32 was compilation tests only with build-many-glibcs.py to verify the ABI baseline updates. I have not done any testing for Hurd, although the float128 support is enabled there as for GNU/Linux.) * sysdeps/i386/Implies: Add ieee754/float128. * sysdeps/x86_64/Implies: Likewise. * sysdeps/x86/bits/floatn.h: New file. * sysdeps/x86/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on x86_64 and x86. * sysdeps/i386/fpu/fenv_private.h: Include <bits/floatn.h>.

* Call exit directly in clone (BZ #21512)Adhemerval Zanella2017-06-261-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On aarch64, alpha, arm, hppa, mips, nios2, powerpc, sh, sparc, tile, and x86_64 the clone syscall jumps to _exit after the child execution and the function ends the process execution by calling exit_group. This behavior have a small issue where threads created with CLONE_THREAD using clone syscall directly will eventually exit the whole group altogether instead of just the thread created. Also, s390, microblaze, ia64, i386, and m68k differs by calling exit syscall directly. This patch changes all architectures to call the exit syscall directly, as for s390, microblaze, ia64, i386, and m68k. This do not have change glibc internal behavior in any sort, since the only usage of clone implementation in posix_spawn calls _exit directly in the created child (fork uses a direct call to clone). Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, powerpc-linux-gnu, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds ULPs for the float128 type, updates the abilist for libc and libm, and adds the files bits/floatn.h and float128-abi.h, in order to enable the new type for powerpc64le. This patch also adds the implementation of sqrtf128 for powerpc64le, since it is not implemented in libgcc. The sfp-machine.h header is taken from libgcc.

* Update x86 ulps for GCC 7.Joseph Myers2017-06-231-0/+3
| | | | | | | | | | Testing with GCC 7 for 32-bit x86 showed some ulps differences, presumably from variation in when values with excess precision get spilled to the stack and so lose that precision.

| | | | | | | | | | | | | | | | | | | | | | | The libm-test-support code clears exceptions at the end of test_exceptions. However, it's possible that exceptions get raised as part of the subsequent checks on the results of the function being tested, and such exceptions then carry through to the next test run and can cause that to fail spuriously. In particular, it's possible for the ulps calculation to raise exceptions in some cases. This patch puts exception clearing at the end of each of the check_* functions, alongside errno clearing, to avoid one test affecting the next in that way. Tested for x86_64 (in conjunction with float128 patches). * libm-test-support.c (check_float_internal): Clear exceptions at end of function. (check_int): Likewise. (check_long): Likewise.

* Avoid localplt issues from x86 fereaiseexcept inline.Joseph Myers2017-06-231-0/+8
| | | | | | | | | | | | | | | | | | | | | | | Building for x86_64 with float128 support, I get a localplt test failure from lrintf128 calling feraiseexcept. The problem is that an inline optimized version of feraiseexcept calls __feraiseexcept_renamed in cases where it doesn't completely expand inline, and that in turn is redirected to feraiseexcept for a library call, so meaning the redirection of feraiseexcept to __GI_feraiseexcept inside libm is lost for that call. This patch fixes the problem by moving the redirect to an internal header in the _LIBC case, with the internal header using __GI_feraiseexcept where appropriate. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/x86/fpu/bits/fenv.h [_LIBC] (__feraiseexcept_renamed): Do not declare. * sysdeps/x86/fpu/include/bits/fenv.h [_LIBC && __USE_EXTERN_INLINES] (__feraiseexcept_renamed): Declare here, redirected to __GI_feraiseexcept if [SHARED && IS_IN (libm)].

This is needed for x86_64, where if building with GCC 6 or earlier there is no __builtin_nansq, so no way to get a signaling NaN of _Float128 type, so associated tests cannot be run (although glibc itself works fine, as there is never any need to create such an sNaN with a built-in function inside glibc).

* Fix float128_private.h redefinition of SET_RESTORE_ROUNDL.Joseph Myers2017-06-221-0/+4
| | | | | | | | | | | | | | | | As with other long double identifiers, float128_private.h has a redefinition of SET_RESTORE_ROUNDL. However, that redefinition is broken, since this is a macro with one argument being defined to take no arguments. This patch fixes the redefinition. (x86_64 needs the redefinition because SET_RESTORE_ROUNDL only changes the x87 rounding mode, whereas _Float128 arithmetic uses the SSE rounding mode instead on x86_64.) Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/float128_private.h [SET_RESTORE_ROUNDF128] (SET_RESTORE_ROUNDL): Take an argument and pass it to SET_RESTORE_ROUNDF128.
* Make float128_private.h work with generic ieee754.h.Joseph Myers2017-06-221-0/+3
| | | | | | | | | | | | | | | | | | float128_private.h redefines ieee754.h identifiers ieee854_long_double and IEEE854_LONG_DOUBLE_BIAS to map them to identifiers from ieee754_float128.h. This causes problems when ieee754.h is included after float128_private.h and it's a version of ieee754.h that also defines those identifiers; specifically, sysdeps/ieee754/ieee754.h, which defines those identifiers for the x86 extended format. This patch fixes this by ensuring an include of ieee754.h from float128_private.h before the redefinitions. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/float128_private.h: Include <ieee754.h>.
* Correct min_of_type handling of _Float128.Joseph Myers2017-06-221-0/+4
| | | | | | | | | | | | | | | | | | | | | The math_private.h macro min_of_type has broken _Float128 handling: instead of passing its type argument to the key __EXPR_FLT128 macro, it passes x, which is not a macro argument but whatever variable called x happens to be visible in the calling function. If that variable has the wrong type, the wrong one of long double and _Float128 can get chosen. In particular, this applies to some _Complex long double functions (where x happens to have type _Complex long double, resulting in min_of_type returning a _Float128 value when it should return a long double value). For some reason, this only caused test failures for me on x86_64 with GCC 6 but not GCC 7 (I suspect it triggers known bugs in conversions from x86 long double to _Float128 that are present in GCC 6's soft-fp). Tested for x86_64 (in conjunction with float128 patches). * sysdeps/generic/math_private.h (__EXPR_FLT128): Do not apply typeof to argument passed to __builtin_types_compatible_p. (min_of_type): Pass type argument, not x, to __EXPR_FLT128.
* Make errno-setting libm templates include errno.h.Joseph Myers2017-06-221-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various type-generic libm wrapper templates, as used for float128, set errno but do not include errno.h. I presume they must get an implicit include from some internal header on powerpc64le; they don't get such an implicit include on x86_64. This patch adds the missing includes of errno.h to each such wrapper. Tested for x86_64 (in conjunction with float128 patches). * math/w_acos_template.c [__USE_WRAPPER_TEMPLATE]: Include <errno.h>. * math/w_acosh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_asin_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_atanh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_cosh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_exp10_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_exp2_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_exp_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_fmod_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_hypot_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_j0_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_j1_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_jn_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_lgamma_r_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_lgamma_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_log10_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_log2_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_log_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_pow_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_remainder_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_sinh_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_sqrt_template.c [__USE_WRAPPER_TEMPLATE]: Likewise. * math/w_tgamma_template.c [__USE_WRAPPER_TEMPLATE]: Likewise.

| | | | | | | | | | | | | | Three float128 files still include xlocale.h after it was removed. I don't know why this didn't cause problems for powerpc64le float128 testing; it did cause problems for my x86_64 float128 testing. This patch changes the includes to use bits/types/locale_t.h.

* Provide an additional macro expansion for F128 in stdlib/tst-strtod.hGabriel F. T. Gomes2017-06-221-0/+6
| | | | | | | | | | | | | | | | The macro F128 in stdlib/tst-strtod.h is defined to provide the literal suffix for _Float128 constants. It uses the macro __f128 (), which is defined in bits/floatn.h to provide the correct literal suffix depending on what is provided by the compiler. However, F128 was not being expanded and only worked correctly, when compiling with GCC 7 (or greater), since F128 is the literal suffix itself. This patch adds an additional macro expansion so that the macro F128 expands to the correct literal suffix on older compilers. * stdlib/tst-strtod.h (MMFUNC): New macro to provide an addition macro expansion.

* x86-64: Implement strcmp family IFUNC selectors in CH.J. Lu2017-06-211-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement strcmp family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. For libc.a, we can't use IFUNC for functions which are called before IFUNC has been initialized. Use IFUNC internally reduces the icache footprint since libc.so and other codes in the process use the same implementations. This patch uses IFUNC for strcmp family functions within libc. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add strcmp-sse2, strcmp-sse4_2, strncmp-sse2, strncmp-sse4_2, strcasecmp_l-sse2, strcasecmp_l-sse4_2, strcasecmp_l-avx, strncase_l-sse2, strncase_l-sse4_2 and strncase_l-avx. * sysdeps/x86_64/multiarch/ifunc-strcasecmp.h: New file. * sysdeps/x86_64/multiarch/strcasecmp.c: Likewise. * sysdeps/x86_64/multiarch/strcasecmp_l-avx.S: Likewise. * sysdeps/x86_64/multiarch/strcasecmp_l-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strcasecmp_l-sse4_2.S: Likewise. * sysdeps/x86_64/multiarch/strcasecmp_l.c: Likewise. * sysdeps/x86_64/multiarch/strcmp-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strcmp-sse4_2.S: Likewise. * sysdeps/x86_64/multiarch/strcmp.c: Likewise. * sysdeps/x86_64/multiarch/strncase.c: Likewise. * sysdeps/x86_64/multiarch/strncase_l-avx.S : Likewise. * sysdeps/x86_64/multiarch/strncase_l-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strncase_l-sse4_2.S: Likewise. * sysdeps/x86_64/multiarch/strncase_l.c: Likewise. * sysdeps/x86_64/multiarch/strncmp-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strncmp-sse4_2.S: Likewise. * sysdeps/x86_64/multiarch/strncmp.c: Likewise. * sysdeps/x86_64/multiarch/strcasecmp_l.S: Removed. * sysdeps/x86_64/multiarch/strcmp.S: Likewise. * sysdeps/x86_64/multiarch/strncase_l.S: Likewise. * sysdeps/x86_64/multiarch/strncmp.S: Likewise. * sysdeps/x86_64/multiarch/strcmp-sse42.S: Include <sysdep.h>.
