* posix: Implement self-contained POSIX barriersSebastian Huber2017-10-059-61/+63
| | | | | | | | POSIX barriers are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3114.
* posix: Implement self-contained POSIX semaphoresSebastian Huber2017-10-058-38/+227
| | | | | | | | | | | | | | For semaphore object pointer and object validation see POSIX_SEMAPHORE_VALIDATE_OBJECT(). Destruction or close of a busy semaphore returns an error status. The object is not flushed. POSIX semaphores are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3116.

| | | | | | | Check iop reference count in close() and return -1 with errno set to EBUSY in case the file descriptor is still in use. Update #3132.

* sparc: Add lazy floating point switchSebastian Huber2017-07-253-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPARC ABI is a bit special with respect to the floating point context. The complete floating point context is volatile. Thus, from an ABI point of view nothing needs to be saved and restored during a context switch. Instead the floating point context must be saved and restored during interrupt processing. Historically, the deferred floating point switch was used for SPARC and the complete floating point context is saved and restored during a context switch to the new floating point unit owner. This is a bit dangerous since post-switch actions (e.g. signal handlers) and context switch extensions may silently corrupt the floating point context. The floating point unit is disabled for interrupt handlers. Thus, in case an interrupt handler uses the floating point unit then this will result in a trap (INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT). In uniprocessor configurations, a lazy floating point context switch is used. In case an active floating point thread is interrupted (PSR[EF] == 1) and a thread dispatch is carried out, then this thread is registered as the floating point owner. When a floating point owner is present during a context switch, the floating point unit is disabled for the heir thread (PSR[EF] == 0). The floating point disabled trap checks that the use of the floating point unit is allowed and saves/restores the floating point context on demand. Update #3077.
