2014-06-25Remove stray includes of kernel-features.h.Joseph Myers
Now that files using __ASSUME_* macros have been made by <https://sourceware.org/ml/libc-alpha/2014-06/msg00543.html> to include <kernel-features.h> directly, any include from a file not using __ASSUME_* macros can safely be removed (as there will no longer be some other file relying on indirect inclusion via a header from which the include is being removed). This patch removes such unnecessary kernel-features.h includes. Tested x86_64 that disassembly of installed shared libraries is unchanged by this patch, except for line numbers in calls to __assert_fail from libc.so and ld.so. 2014-06-23 Joseph Myers

2014-06-20Include <kernel-features.h> explicitly where required.Joseph Myers
This patch makes files using __ASSUME_* macros include <kernel-features.h> explicitly, rather than relying on some other header (such as tls.h, lowlevellock.h or pthreadP.h) to include it implicitly. (I omitted cases where I've already posted or am testing the patch that stops the file from needing __ASSUME_* at all.) This accords with the general principle of making source files include the headers for anything they use, and also helps make it safe to remove <kernel-features.h> includes from any file that doesn't use __ASSUME_* (some of those may be stray includes left behind after increasing the minimum kernel version, others may never have been needed or may have become obsolete after some other change).

2014-06-20Remove __ASSUME_SOCK_CLOEXEC / SOCK_CLOEXEC conditionals in Linux-specific code.Joseph Myers
This patch removes conditionals on __ASSUME_SOCK_CLOEXEC, and on SOCK_CLOEXEC being defined, in Linux-specific code, now that all supported Linux kernel versions can be assumed to have this functionality. (The macro is also used in OS-independent code and is not defined for Hurd.)

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.

2014-05-09S/390: Port of lock elision to System/zDominik Vogt
Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built.

2014-04-17PowerPC: Sync pthread_once with default implementationAdhemerval Zanella
This patch removes the arch specific powerpc implementation and instead uses the linux default one. Although the current powerpc implementation already constains the required memory barriers for correct initialization, the default implementation shows a better performance on newer chips.
2014-04-11Fixed and unified pthread_once.Torvald Riegel
[BZ #15215] This unifies various pthread_once architecture-specific implementations which were using the same algorithm with slightly different implementations. It also adds missing memory barriers that are required for correctness.
