* [PR19826] fix non-LE TLS in static programsAlexandre Oliva2016-09-214-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | An earlier fix for TLS dropped early initialization of DTV entries for modules using static TLS, leaving it for __tls_get_addr to set them up. That worked on platforms that require the GD access model to be relaxed to LE in the main executable, but it caused a regression on platforms that allow GD in the main executable, particularly in statically-linked programs: they use a custom __tls_get_addr that does not update the DTV, which fails when the DTV early initialization is not performed. In static programs, __libc_setup_tls performs the DTV initialization for the main thread, but the DTV of other threads is set up in _dl_allocate_tls_init, so that's the fix that matters. Restoring the initialization in the remaining functions modified by this patch was just for uniformity. It's not clear that it is ever needed: even on platforms that allow GD in the main executable, the dynamically-linked version of __tls_get_addr would set up the DTV entries, even for static TLS modules, while updating the DTV counter. for ChangeLog [BZ #19826] * elf/dl-tls.c (_dl_allocate_tls_init): Restore DTV early initialization of static TLS entries. * elf/dl-reloc.c (_dl_nothread_init_static_tls): Likewise. * nptl/allocatestack.c (init_one_static_tls): Likewise.

* [soft-fp] Add support for various half-precision conversion routines.James Greenhalgh2016-09-218-0/+465
| | | | | | | | | | | | | | | | | | | | | This patch adds conversion routines required for _Float16 support in AArch64. These are one-step conversions to and from TImode and TFmode. We need these on AArch64 regardless of presence of the ARMv8.2-A 16-bit floating-point extensions. In the patch, soft-fp/half.h is derived from soft-fp/single.h . The conversion routines are derivatives of their respective SFmode variants. * soft-fp/extendhftf2.c: New. * soft-fp/fixhfti.c: Likewise. * soft-fp/fixunshfti.c: Likewise. * soft-fp/floattihf.c: Likewise. * soft-fp/floatuntihf.c: Likewise. * soft-fp/half.h: Likewise. * soft-fp/trunctfhf2.c: Likewise.
* Add issubnormal.Joseph Myers2016-09-216-4/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TS 18661-1 adds an issubnormal classification macro to <math.h>. This patch implements it for glibc. There are no new underlying functions in libm because the implementation uses fpclassify; any optimizations for this macro should be done through adding __builtin_subnormal in GCC and using it in the header for suitable GCC versions, not through adding other optimized inline or out-of-line versions to glibc. The intended structure of the NEWS entry for <math.h> features from TS 18661-1 is like: * New <math.h> features are added from TS 18661-1:2014: - Nearest integer functions: roundeven, roundevenf, roundevenl. - Comparison macros: iseqsig. - Classification macros: iscanonical, issubnormal, iszero. (that is, following the grouping of interfaces in TS 18661-1:2014, with any group where any interfaces are new in glibc 2.25 being listed like that). Tested for x86_64 and x86. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (issubnormal): New macro. * math/libm-test.inc (issubnormal_test_data): New array. (issubnormal_test): New function. * manual/arith.texi (Floating Point Classes): Document issubnormal. * manual/libm-err-tab.pl: Update comment on interfaces without ulps tabulated.
* Add <stdint.h> integer width macros.Joseph Myers2016-09-217-4/+322
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TS 18661-1 defines macros for the width of integer types, intended for use with the fromfp functions to convert from floating-point types to integer types of any width, in any rounding mode and with control over whether "inexact" is raised. Such macros are, of course, more generally useful than just with those functions. Those macros are added to <limits.h> and <stdint.h>. Having previously added the <limits.h> macros, this patch adds the <stdint.h> ones. I've also added these macros to GCC's headers for GCC 7, but for glibc systems, the definitions in GCC's <stdint.h> will only be used with -ffreestanding. Tested for x86_64 and x86. * sysdeps/generic/stdint.h: Define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION and include <bits/libc-header-start.h> instead of including <features.h>.

* Build s_nan* objects from a generic templatePaul E. Murphy2016-09-2012-83/+42
| | | | | | | This requires adding a macro to synthesize the call to __strto*_nan. Since this is likely to be the only usage ever for strto* functions in generated libm calls, a dedicated macro is defined for it.
* Remove __nan{f,,l} macrosPaul E. Murphy2016-09-206-11/+12

* Make ldexpF generic.Paul E. Murphy2016-09-209-90/+115
| | | | | | | | | | | | | | | | | This one is a little more tricky since it is built both for libm and libc, and exports multiple aliases. To simplify aliasing, a new macro is introduced which handles aliasing to two symbols. By default, it just applies declare_mgen_alias to both target symbols. Likewise, the makefile is tweaked a little to generate templates for shared files too, and a new rule is added to build m_*.c objects from the objpfx directory. Verified there are no symbol or code changes using a script to diff the *_ldexp* object files on s390x, aarch64, arm, x86_64, and ppc64.

| | | | | | | | | | | | | | Current sparc32 sem_init and default one only differ on sem.newsem.pad initialization. This patch removes sparc32 and sparc32v9 sem_init arch specific implementation and set sparc32 to use nptl default one. The default implementation sets the required sem.newsem.pad to 0 (which is ununsed in other architectures).

In this scenario only atomics are involved and thus the futex cancellable call is not issue and a pending cancellation signal is not handled. The fix is straighforward by calling pthread_testcancel is both function start. Although it would be simpler to call CANCELLATION_P directly, I decided to add an internal pthread_testcancel alias and use it to export less internal implementation on such function. A possible change on how pthread_testcancel is internally implemented would lead to either continue to force use CANCELLATION_P or to adjust its every use. GLIBC testcase also does have tests for uncontended cases, test-cancel12 and test-cancel14.c, however both are flawed by adding another cancellation point just after thread pthread_cleanup_pop: 47 static void * 48 tf (void *arg) 49 { 50 pthread_cleanup_push (cleanup, NULL); 51 52 int e = pthread_barrier_wait (&bar); 53 if (e != 0 && e != PTHREAD_BARRIER_SERIAL_THREAD) 54 { 55 puts ("tf: 1st barrier_wait failed"); 56 exit (1); 57 } 58 59 /* This call should block and be cancelable. */ 60 sem_wait (&sem); 61 62 pthread_cleanup_pop (0); 63 64 puts ("sem_wait returned"); 65 66 return NULL; 67 } So sem_{timed}wait does not act on cancellation, pthread_cleanup_pop executes 'cleanup' and then 'puts' acts on cancellation. Since pthread_cleanup_pop removed the clean-up handler, it will ran only once and thus it won't accuse an error to indicate sem_wait has not acted on the cancellation signal. This patch also fixes this behavior by removing the cancellation point 'puts'. It also adds some cleanup on all sem_{timed}wait cancel tests. It partially fixes BZ #18243. Checked on x86_64.

| | | | | | | | | | | | | | | | | | | | Current sparc32 sem_open and default one only differ on: 1. Default one contains a 'futex_supports_pshared' check. 2. sem.newsem.pad is initialized to zero.

Using 1. is fine since it should always evaluate 0 for Linux (an optimized away by the compiler). Adding 2. to default implementation should be ok since 'pad' field is used mainly on sparc32 code.

* Remove the ptw-% patternsFlorian Weimer2016-09-147-19/+38
| | | | | | | | | | Nothing depends on the PTW macro anymore, so the mechanism to define PTW for recompliations of libc routines is no longer needed.

* ldbl-128: Use L(x) macro for long double constantsPaul E. Murphy2016-09-1351-3925/+3983
| | | | | | | | | | | | | | | | | | | | This runs the attached sed script against these files using a regex which aggressively matches long double literals when not obviously part of a comment. Likewise, 5 digit or less integral constants are replaced with integer constants, excepting the two cases of 0 used in large tables, which are also the only integral values of the form x.0*E0L encountered within these converted files. Likewise, -L(x) is transformed into L(-x). Naturally, the script has a few minor hiccups which are more clearly remedied via the attached fixup patch. Such hiccups include, context-sensitive promotion to a real type, and munging constants inside harder to detect comment blocks.

* Remove __libc_csu_irel declarationSiddhesh Poyarekar2016-09-102-3/+4
| | | | | | | | 21ad055803de5dd03606588753c46fbf8a5863b2 removed the function, but missed the declaration in libc-start. Removed and verified that the generated assembly is unchanged. * csu/libc-start.c (__libc_csu_irel): Remove declaration.
* Add e500 version of fetestexceptflag.Joseph Myers2016-09-072-0/+28
| | | | | | | | | | | | | | | When I added fetestexceptflag, I missed that e500 was another case that needed its own version because saved exceptions were not directly stored in a form that could be ANDed with exception bits (they were stored with exceptions in SPE form, but the FE_* macros always use the classic hard-float form). This patch adds an e500 version with the required call to __fexcepts_from_spe to convert from one form to the other. Tested for e500. * sysdeps/powerpc/powerpc32/e500/nofpu/fetestexceptflag.c: New file.
* Add femode_t functions: sparc.Joseph Myers2016-09-073-0/+67
