2015-07-10Add and use new glibc-internal futex API.Torvald Riegel
This adds new functions for futex operations, starting with wait, abstimed_wait, reltimed_wait, wake. They add documentation and error checking according to the current draft of the Linux kernel futex manpage. Waiting with absolute or relative timeouts is split into separate functions. This allows for removing a few cases of code duplication in pthreads code, which uses absolute timeouts; also, it allows us to put platform-specific code to go from an absolute to a relative timeout into the platform-specific futex abstractions.. Futex operations that can be canceled are also split out into separate functions suffixed by "_cancelable". There are separate versions for both Linux and NaCl; while they currently differ only slightly, my expectation is that the separate versions of lowlevellock-futex.h will eventually be merged into futex-internal.h when we get to move the lll_ functions over to the new futex API.
2015-06-30Clean up BUSY_WAIT_NOP and atomic_delay.Torvald Riegel
This patch combines BUSY_WAIT_NOP and atomic_delay into a new atomic_spin_nop function and adjusts all clients. The new function is put into atomic.h because what is best done in a spin loop is architecture-specific, and atomics must be used for spinning. The function name is meant to tell users that this has no effect on synchronization semantics but is a performance aid for spinning.
2015-06-17Fix mq_notify pthread_barrier_* namespace (bug 18544).Joseph Myers
mq_notify (present in POSIX by 1996) brings in references to pthread_barrier_init and pthread_barrier_wait (new in the 2001 edition of POSIX). This patch fixes this by making those functions into weak aliases of __pthread_barrier_*, exporting the __pthread_barrier_* names at version GLIBC_PRIVATE and using them in mq_notify. Tested for x86_64 and x86 (testsuite, and comparison of installed stripped shared libraries). Changes in addresses from dynamic symbol table / PLT changes render most comparisons not particularly useful, but when the addresses of subsequent code don't change there's no sign of unexpected changes there. This patch does not remove any linknamespace XFAILs because of other namespace issues remaining with mqueue.h functions. [BZ #18544] * nptl/pthread_barrier_init.c (pthread_barrier_init): Rename to __pthread_barrier_init and define as weak alias of __pthread_barrier_init. * sysdeps/sparc/nptl/pthread_barrier_init.c (pthread_barrier_init): Likewise. * nptl/pthread_barrier_wait.c (pthread_barrier_wait): Rename to __pthread_barrier_wait and define as weak alias of __pthread_barrier_wait. * sysdeps/sparc/nptl/pthread_barrier_wait.c (pthread_barrier_wait): Likewise. * sysdeps/sparc/sparc32/pthread_barrier_wait.c (pthread_barrier_wait): Likewise. * sysdeps/unix/sysv/linux/i386/i486/pthread_barrier_wait.S (pthread_barrier_wait): Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_barrier_wait.S (pthread_barrier_wait): Likewise. * nptl/Versions (libpthread): Export __pthread_barrier_init and __pthread_barrier_wait at version GLIBC_PRIVATE. * include/pthread.h (__pthread_barrier_init): Declare.

2015-06-17Fix sem_* tdelete, tfind, tsearch, twalk namespace (bug 18536).Joseph Myers
The sem_* functions bring in references to tdelete, tfind, tsearch and twalk. But the t* functions are XSI-shaded, while sem_* aren't. This patch fixes this by using __t* instead, exporting those functions from libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and using libc_hidden_* for the benefit of calls within libc. Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). libpthread gets changes from PLT reordering; addresses in libc change because of PLT / dynamic symbol table changes. [BZ #18536] * misc/tsearch.c (__tsearch): Use libc_hidden_def. (__tfind): Likewise. (__tdelete): Likewise.

This causes linknamespace test failures - except on x86 / x86_64, where feraiseexcept is inline (for the relevant constant arguments) in bits/fenv.h. This patch fixes this by making those functions call __feraiseexcept instead. All changes are applied to all architectures rather than considering the possibility that some might not be needed in some cases (e.g. x86) as it seems most maintainable to keep architectures consistent. Where __feraiseexcept does not exist, it is added, with feraiseexcept made a weak alias; where it is a strong alias, it is made weak. libm_hidden_def / libm_hidden_proto are used with __feraiseexcept (this might in some cases improve code generation for existing calls to __feraiseexcept in some code on some architectures). Where there are dummy feraiseexcept macros (on architectures without floating-point exceptions support, to avoid compile errors from references to undefined FE_* macros), corresponding dummy __feraiseexcept macros are added. And on x86, to ensure __feraiseexcept calls still get inlined, the inline function in bits/fenv.h is refactored so that most of it can be reused in an inline __feraiseexcept in a separate include/bits/fenv.h. Calls are changed in C90/UNIX98 functions, but generally not in functions missing from those standards. They are also changed in libc_fe* functions (on the basis that those might be used in any libm function), and in feupdateenv (on the same basis - may be used, via default libc_*, in any libm function - of course feupdateenv will need changing to __feupdateenv in a subsequent patch to make that fully namespace-clean). No __feraiseexcept is added corresponding to the feraiseexcept in powerpc bits/fenvinline.h, because that macro definition is conditional on !defined __NO_MATH_INLINES, and glibc libm is built with -D__NO_MATH_INLINES, so changing internal calls to use __feraiseexcept should make no difference. Tested for x86_64 (testsuite; the only change in disassembly of installed shared libraries is a slight code reordering in clog10, of no apparent significance). Also tested for MIPS, where (in the configuration tested) it eliminates math.h linknamespace failures for n32 and n64 (some for o32 remain because of other issues).

2014-11-04Don't use INTDEF/INTUSE with _dl_init (bug 14132).Joseph Myers
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch eliminates its use for _dl_init. Since _dl_init was already declared with hidden visibility, creating a second hidden alias for it was completely pointless, so this patch replaces all uses of _dl_init_internal with plain _dl_init instead of using hidden_proto / hidden_def (which are only needed when you want a hidden alias for a non-hidden symbol; it's quite possible there are cases where they are used but don't need to be because the symbol in question is not part of the public ABI and is only used within a single library, so using attributes_hidden instead would suffice). Tested for x86_64 that installed stripped shared libraries are unchanged by the patch.

2014-10-09soft-fp: Refactor exception handling for comparisons.Joseph Myers
This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro.

2014-10-09soft-fp: Remove FP_CLEAR_EXCEPTIONS.Joseph Myers
As noted in <https://sourceware.org/ml/libc-alpha/2013-10/msg00516.html>, the soft-fp macro FP_CLEAR_EXCEPTIONS should not be necessary, as soft-fp code should never set an exception and later clear it. In fact, all four uses in glibc (for SPARC) are indeed unnecessary: they appear in files that convert 32-bit or 64-bit integers to IEEE binary128, an operation that can never raise any exceptions. If this was intended to enable the compiler to optimize away any FP_FROM_INT code testing for exceptional cases, we now have a better way of doing this: defining FP_NO_EXCEPTIONS before including soft-fp.h causes all code handling exceptions to be stubbed out, and the rounding mode to be hardwired for round-to-zero, to allow such optimizations for source files where (a) the operation in question, for the particular types in question, can never raise exceptions, but (b) some instances of the operation for other types can, so the macros used in the file do contain references to rounding or exceptions, albeit dead in that particular file. The uses in the Linux kernel are also unnecessary (clearing exceptions at a point where they are already cleared). This patch duly removes FP_CLEAR_EXCEPTIONS, making the SPARC code in question use FP_NO_EXCEPTIONS and stop using exception-related macros. * soft-fp/soft-fp.h (FP_CLEAR_EXCEPTIONS): Remove macro. * sysdeps/sparc/sparc32/soft-fp/q_itoq.c: Define FP_NO_EXCEPTIONS.

2014-06-13Add adaptive elision to rwlocksAndi Kleen
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.
