* sparc: Use atomic compiler builtins on sparcAdhemerval Zanella2019-11-2715-902/+166
| | | | | | | | | | | | | | | | | This patch removes the arch-specific atomic instruction, relying on compiler builtins. The __sparc32_atomic_locks support is removed and a configure check is added to check if compiler uses libatomic to implement CAS. It also removes the sparc specific sem_* and pthread_barrier_* implementations. It in turn allows buidling against a LEON3/LEON4 sparcv8 target, although it will still be incompatible with generic sparcv9. Checked on sparcv9-linux-gnu and sparc64-linux-gnu. I also checked with build against sparcv8-linux-gnu with -mcpu=leon3. Tested-by: Andreas Larsson <andreas@gaisler.com>
* Remove 32 bit sparc v7 supportAdhemerval Zanella2019-11-2724-2702/+410
| | | | | | | | | | | | | | | | | | The patch is straighforward: - The sparc32 v8 implementations are moved as the generic ones. - A configure test is added to check for either __sparc_v8__ or __sparc_v9__. - The triple names are simplified and sparc implies sparcv8. The idea is to keep support on sparcv8 architectures that does support CAS instructions, such as LEON3/LEON4. Checked on a sparcv9-linux-gnu and sparc64-linux-gnu.

* nptl: Add default pthreadtypes-arch.hAdhemerval Zanella2019-11-261-45/+0
| | | | | | | | | | | | | | | | | | | | | | | This patch adds a default pthreadtypes-arch.h, the idea is to simpify new ports inclusion and an override is required only if the architecture adds some arch-specific extensions or requirement. The default values on the new generic header are based on current architecture define value and they are not optimal compared to current code requirements as below. - On 64 bits __SIZEOF_PTHREAD_BARRIER_T is defined as 32 while is sizeof (struct pthread_barrier) is 20 bytes. - On 32 bits __SIZEOF_PTHREAD_ATTR_T is defined as 36 while sizeof (struct pthread_attr) is 32. The default values are not changed so the generic header could be used by some architectures. Checked with a build on affected abis. Change-Id: Ie0cd586258a2650f715c1af0c9fe4e7063b0409a
* nptl: Add struct_rwlock.hAdhemerval Zanella2019-11-262-27/+58
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new generic __pthread_rwlock_arch_t definition meant to be used by new ports. Its layout mimics the current usage on some 64 bits ports and it allows some ports to use the generic definition. The arch __pthread_rwlock_arch_t definition is moved from pthreadtypes-arch.h to another arch-specific header (struct_rwlock.h). Also the static intialization macro for pthread_rwlock_t is set to use an arch defined on (__PTHREAD_RWLOCK_INITIALIZER) which simplifies its implementation. The default pthread_rwlock_t layout differs from current ports with: 1. Internal layout is the same for 32 bits and 64 bits. 2. Internal flag is an unsigned short so it should not required additional padding to align for word boundary (if it is the case for the ABI). Checked with a build on affected abis.

* nptl: Add struct_mutex.hAdhemerval Zanella2019-11-261-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current way of defining the common mutex definition for POSIX and C11 on pthreadtypes-arch.h (added by commit 06be6368da16104be5) is not really the best options for newer ports. It requires define some misleading flags that should be always defined as 0 (__PTHREAD_COMPAT_PADDING_MID and __PTHREAD_COMPAT_PADDING_END), it exposes options used solely for linuxthreads compat mode (__PTHREAD_MUTEX_USE_UNION and __PTHREAD_MUTEX_NUSERS_AFTER_KIND), and requires newer ports to explicit define them (adding more boilerplate code). This patch adds a new default __pthread_mutex_s definition meant to be used by newer ports. Its layout mimics the current usage on both 32 and 64 bits ports and it allows most ports to use the generic definition. Only ports that use some arch-specific definition (such as hardware lock-elision or linuxthreads compat) requires specific headers. For 32 bit, the generic definitions mimic the other 32-bit ports of using an union to define the fields uses on adaptive and robust mutexes (thus not allowing both usage at same time) and by using a single linked-list for robust mutexes. Both decisions seemed to follow what recent ports have done and make the resulting pthread_mutex_t/mtx_t object smaller. Also the static intialization macro for pthread_mutex_t is set to use a macro __PTHREAD_MUTEX_INITIALIZER where the architecture can redefine in its struct_mutex.h if it requires additional fields to be initialized. Checked with a build on affected abis. Change-Id: I30a22c3e3497805fd6e52994c5925897cffcfe13

| | | | | | | | | | | | | This patch new build tests to check for internal fields offsets for internal pthread_rwlock_t definition. Althoug the '__data.__flags' field layout should be preserved due static initializators, the patch also adds tests for the futexes that may be used in a shared memory (although using different libc version in such scenario is not really supported).

* nptl: Replace non cancellable pause/nanosleep with futexAdhemerval Zanella2019-10-312-43/+0
| | | | | | | | | | | | | | | | | | | | | | | | To help y2038 work avoid duplicate all the logic of nanosleep on non cancellable version, the patch replace it with a new futex operation, lll_timedwait. The changes are: - Add a expected value for __lll_clocklock_wait, so it can be used to wait for generic values. - Remove its internal atomic operation and move the logic to __lll_clocklock. It makes __lll_clocklock_wait even more generic and __lll_clocklock slight faster on fast-path (since it won't require a function call anymore). - Add lll_timedwait, which uses __lll_clocklock_wait, to replace both __pause_nocancel and __nanosleep_nocancel. It also allows remove the sparc32 __lll_clocklock_wait implementation (since it is similar to the generic one). Checked on x86_64-linux-gnu, sparcv9-linux-gnu, and i686-linux-gnu.

* Split up endian.h to minimize exposure of BYTE_ORDER.Alistair Francis2019-10-012-6/+10

This patch creates a new bits/endian.h that can be included by any header that wants to be able to test __BYTE_ORDER and/or __FLOAT_WORD_ORDER against the __*_ENDIAN constants, or needs __LONG_LONG_PAIR. It only defines macros in the implementation namespace. The existing bits/endian.h (which could not be included independently of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER) is renamed to bits/endianness.h. I also took the opportunity to canonicalize the form of this header, which we are stuck with having one copy of per architecture. Since they are so short, this means git doesn’t understand that they were renamed from existing headers, sigh. endian.h itself is a nonstandard header and its only remaining use from a standard header is guarded by __USE_MISC, so I dropped the __USE_MISC conditionals from around all of the public-namespace things it defines. (This means, an application that requests strict library conformance but includes endian.h will still see the definition of BYTE_ORDER.) A few changes to specific bits/endian(ness).h variants deserve mention: - sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did have selectable endianness, but we have assembly code in sysdeps/ia64 that assumes it’s little-endian, so there is no reason to treat the ia64 endianness.h as linux-specific. - The C-SKY port does not fully support big-endian mode, the compile will error out if __CSKYBE__ is defined. - The PowerPC port had extra logic in its bits/endian.h to detect a broken compiler, which strikes me as unnecessary, so I removed it. - The only files that defined __FLOAT_WORD_ORDER always defined it to the same value as __BYTE_ORDER, so I removed those definitions. The SH bits/endian(ness).h had comments inconsistent with the actual setting of __FLOAT_WORD_ORDER, which I also removed. - I *removed* copyright boilerplate from the few bits/endian(ness).h headers that had it; these files record a single fact in a fashion dictated by an external spec, so I do not think they are copyrightable. As long as I was changing every copy of ieee754.h in the tree, I noticed that only the MIPS variant includes float.h, because it uses LDBL_MANT_DIG to decide among three different versions of ieee854_long_double. This patch makes it not include float.h when GCC’s intrinsic __LDBL_MANT_DIG__ is available. * string/endian.h: Unconditionally define LITTLE_ENDIAN, BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER.

* Fix output of LD_SHOW_AUXV=1.Stefan Liebler2019-03-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit 1616d034b61622836d3a36af53dcfca7624c844e the output was corrupted on some platforms as _dl_procinfo was called for every auxv entry and on some architectures like s390 all entries were represented as "AT_HWCAP". This patch is removing the condition and let _dl_procinfo decide if an entry is printed in a platform specific or generic way. This patch also adjusts all _dl_procinfo implementations which assumed that they are only called for AT_HWCAP or AT_HWCAP2. They are now just returning a non-zero-value for entries which are not handled platform specifc. ChangeLog: * elf/dl-sysdep.c (_dl_show_auxv): Remove condition and always call _dl_procinfo. * sysdeps/unix/sysv/linux/s390/dl-procinfo.h (_dl_procinfo): Ignore types other than AT_HWCAP. * sysdeps/sparc/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/powerpc/dl-procinfo.h (_dl_procinfo): Adjust comment in the case of falling back to generic output mechanism. * sysdeps/unix/sysv/linux/arm/dl-procinfo.h (_dl_procinfo): Likewise.

* Fix SPARC64 handling of R_SPARC_H34 (bug 24231).Joseph Myers2019-02-181-0/+1
| | | | | | | | | | | | | | | | Building glibc with -Wextra shows a -Wimplicit-fallthrough warning for SPARC64 that appears to be a real bug in glibc. The dynamic linker handling of R_SPARC_H34 falls through to that of R_SPARC_H44, which in the case of this code is nonsensical (it means the value computed for R_SPARC_H34 gets overwritten by one computed with the different logic for R_SPARC_H44). Thus, this patch adds the missing break there. Note: I do not have a testcase to demonstrate this bug. Tested with build-many-glibcs.py. [BZ #24231] * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Add break after R_SPARC_H34 case.
* nptl: Reinstate pthread_timedjoin_np as a cancellation point (BZ#24215)Adhemerval Zanella2019-02-142-41/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch ce7eb0e90315 ("nptl: Cleanup cancellation macros") changed the join sequence for internal common __pthread_timedjoin_ex to use the new macro lll_wait_tid. The idea was this macro would issue the cancellable futex operation depending whether the timeout is used or not. However if a timeout is used, __lll_timedwait_tid is called and it is not a cancellable entrypoint. This patch fixes it by simplifying the code in various ways: - Instead of adding the cancellation handling on __lll_timedwait_tid, it moves the generic implementation to pthread_join_common.c (called now timedwait_tid with some fixes to use the correct type for pid). - The llvm_wait_tid macro is removed, along with its replication on x86_64, i686, and sparc arch-specific lowlevellock.h. - sparc32 __lll_timedwait_tid is also removed, since the code is similar to generic one. - x86_64 and i386 provides arch-specific __lll_timedwait_tid which is also removed since they are similar in functionality to generic C code and there is no indication it is better than compiler generated code. New tests, tst-join8 and tst-join9, are provided to check if pthread_timedjoin_np acts as a cancellation point. Checked on x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, and aarch64-linux-gnu.

The redirection used to ensure that __ieee754_sqrt does still get called when the compiler doesn't inline a built-in function expansion is refactored so it can be applied to other functions; the refactoring is arranged so it's not limited to unary functions either (it would be reasonable to use this mechanism for copysign - removing the inline in math_private_calls.h but also eliminating unnecessary local PLT entry use in the cases (powerpc soft-float and e500v1, for IBM long double) where copysign calls don't get inlined). The point of this change is that more architectures can get floor calls inlined where they weren't previously (AArch64, for example), without needing special inline definitions in their math_private.h, and existing such definitions in math_private.h headers can be removed. Note that it's possible that in some cases an inline may be used where an IFUNC call was previously used - this is the case on x86_64, for example. I think the direct calls to floor are still appropriate; if there's any significant performance cost from inline SSE2 floor instead of an IFUNC call ending up with SSE4.1 floor, that indicates that either the function should be doing something else that's faster than using floor at all, or it should itself have IFUNC variants, or that the compiler choice of inlining for generic tuning should change to allow for the possibility that, by not inlining, an SSE4.1 IFUNC might be called at runtime - but not that glibc should avoid calling floor internally. (After all, all the same considerations would apply to any user program calling floor, where it might either be inlined or left as an out-of-line call allowing for a possible IFUNC.)

* Split fenv_private.h out of math_private.h more consistently.Joseph Myers2018-08-282-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some architectures, the parts of math_private.h relating to the floating-point environment are in a separate file fenv_private.h included from math_private.h. As this is purely an architecture-specific convention used by several architectures, however, all such architectures still need their own math_private.h, even if it has nothing to do beyond #include <fenv_private.h> and peculiarity of including the i386 file directly instead of having a shared file in sysdeps/x86. This patch makes the fenv_private.h name an architecture-independent convention in glibc. The include of fenv_private.h from math_private.h becomes architecture-independent (until callers are updated to include fenv_private.h directly so the include from math_private.h is no longer needed). Some architecture math_private.h headers are removed if no longer needed, or renamed to fenv_private.h if all they define belongs in that header; architecture fenv_private.h headers now do require #include_next <fenv_private.h>. The i386 fenv_private.h file moves to sysdeps/x86/fpu/ to reflect how it is actually shared with x86_64. The generic math_private.h gets a new include of <stdbool.h>, as needed for bool in some prototypes in that header (previously that was indirectly included via include/fenv.h, which now only gets included too late in math_private.h, after those prototypes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/aarch64/fpu/fenv_private.h: New file.

This patch eliminates the sysdeps/sparc/sparc64/soft-fp directory accordingly, merging its contents into sysdeps/sparc/sparc64. This completes removing the unnecessary <arch>/soft-fp sysdeps directories. sysdeps/sparc/sparc64/soft-fp/e_ilogbl.c is removed rather than moved. It was not in fact used previously - the ldbl-128 version of e_ilogbl.c was used instead - and moving it into sysdeps/sparc/sparc64 results in it being used, but causing a build failure because of FP_DECL_EX declaring an unused variable (as I noted in <https://sourceware.org/ml/libc-alpha/2013-10/msg00457.html> that file doesn't appear to use FP_DECL_EX). Given that the file was previously unused and so presumably not tested recently, removing it is the safe way to avoid this patch changing what actually gets built into glibc (if this file should turn out more efficient than the ldbl-128 e_ilogbl.c, it can always be added back in future with the build failure fixed).

* elf: Unify symbol address run-time calculation [BZ #19818]Maciej W. Rozycki2018-04-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wrap symbol address run-time calculation into a macro and use it throughout, replacing inline calculations. There are a couple of variants, most of them different in a functionally insignificant way. Most calculations are right following RESOLVE_MAP, at which point either the map or the symbol returned can be checked for validity as the macro sets either both or neither. In some places both the symbol and the map has to be checked however. My initial implementation therefore always checked both, however that resulted in code larger by as much as 0.3%, as many places know from elsewhere that no check is needed. I have decided the size growth was unacceptable. Having looked closer I realized that it's the map that is the culprit. Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional boolean argument telling it to access the map without checking it for validity. This in turn has brought quite nice results, with new code actually being smaller for i686, and MIPS o32, n32 and little-endian n64 targets, unchanged in size for x86-64 and, unusually, marginally larger for big-endian MIPS n64, as follows: i686: text data bss dec hex filename 152255 4052 192 156499 26353 ld-2.27.9000-base.so 152159 4052 192 156403 262f3 ld-2.27.9000-elf-symbol-value.so MIPS/o32/el: text data bss dec hex filename 142906 4396 260 147562 2406a ld-2.27.9000-base.so 142890 4396 260 147546 2405a ld-2.27.9000-elf-symbol-value.so MIPS/n32/el: text data bss dec hex filename 142267 4404 260 146931 23df3 ld-2.27.9000-base.so 142171 4404 260 146835 23d93 ld-2.27.9000-elf-symbol-value.so MIPS/n64/el: text data bss dec hex filename 149835 7376 408 157619 267b3 ld-2.27.9000-base.so 149787 7376 408 157571 26783 ld-2.27.9000-elf-symbol-value.so MIPS/o32/eb: text data bss dec hex filename 142870 4396 260 147526 24046 ld-2.27.9000-base.so 142854 4396 260 147510 24036 ld-2.27.9000-elf-symbol-value.so MIPS/n32/eb: text data bss dec hex filename 142019 4404 260 146683 23cfb ld-2.27.9000-base.so 141923 4404 260 146587 23c9b ld-2.27.9000-elf-symbol-value.so MIPS/n64/eb: text data bss dec hex filename 149763 7376 408 157547 2676b ld-2.27.9000-base.so 149779 7376 408 157563 2677b ld-2.27.9000-elf-symbol-value.so x86-64: text data bss dec hex filename 148462 6452 400 155314 25eb2 ld-2.27.9000-base.so 148462 6452 400 155314 25eb2 ld-2.27.9000-elf-symbol-value.so [BZ #19818] * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Add `set' parameter.

* Remove powerpc, sparc fdim inlines (bug 22987).Joseph Myers2018-03-201-57/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc and sparc bits/mathinline.h include inlines of fdim and fdimf. These are not restricted to -fno-math-errno, but do not set errno, and wrongly use ordered <= comparisons instead of the required islessequal comparisons (this latter issue is latent on powerpc because GCC wrongly uses unordered comparison instructions for operations that should use ordered comparison instructions). Since we wish to avoid such header inlines anyway, leaving it to the compiler to inline such standard functions under appropriate conditions, this patch fixes those issues by removing the inlines in question (and thus removing the sparc bits/mathinline.h header which had no other inlines left in it). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85003> for adding correct fdim inlines to GCC, since the function is simple enough that a correct inline is a perfectly reasonable architecture-independent optimization with -fno-math-errno and in the absence of implicit excess precision. Tested with build-many-glibcs.py for all its powerpc and sparc configurations. [BZ #22987] * sysdeps/powerpc/bits/mathinline.h (fdim): Remove inline function.

Note that removing inlines for __ieee754_sqrt disables inlining in the sqrt wrapper functions.
