Shawn O. Pearce 028ef0de 2008-12-31T13:20:21 Add a mutex and atomic counter abstraction and implementations These abstractions can be used to implement an efficient resource reference counter and simple mutual exclusion. On pthreads we use pthread_mutex_t, except when we are also on glibc and can directly use its asm/atomic.h definitions. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Andreas Ericsson 36f0f61f 2008-11-18T19:06:25 Add compiler/platform agnostic thread-local storage It doesn't cover all cases, but we can work on those as we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++, Sun Studio C/C++ and Borland C++ Builder are the supported compilers (although we boldly assume that they all are of a recent enough version to support thread-local storage). This is intended to be used in upcoming patches that implement graceful (but TLS-dependant) error-handling in the library. As an added bonus, we also bring the online_cpus() function from git.git to detect the number of usable cpu's. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.
