The first 7 patches together implement a version of C threads (my v. 8.6) as they are described in C11 section 7.26. It is entirely based on musl's pthread implementation, and since C11 leaves a lot of leeway for interpretation, it follows POSIX semantics wherever this is possible. The 8th and 9th patch are optional, and implements a stricter separation between pthread_create and thrd_create, my version 9.7. Jens Gustedt (9): interface additions for the C thread implementation additions to src/time and some implied minor changes here and there use weak symbols for the POSIX functions that will be used by C threads add the functions for tss_t and once_flag add the functions for mtx_t add the functions for cnd_t add the thrd_xxxxxx functions separate pthread_create and pthread_exit in two different TU Separate pthread_create and thrd_create arch/arm/bits/alltypes.h.in | 10 +- arch/i386/bits/alltypes.h.in | 10 +- arch/microblaze/bits/alltypes.h.in | 10 +- arch/mips/bits/alltypes.h.in | 10 +- arch/or1k/bits/alltypes.h.in | 10 +- arch/powerpc/bits/alltypes.h.in | 10 +- arch/sh/bits/alltypes.h.in | 10 +- arch/x32/bits/alltypes.h.in | 10 +- arch/x86_64/bits/alltypes.h.in | 10 +- include/alltypes.h.in | 10 ++ include/threads.h | 110 ++++++++++++++++++ include/time.h | 11 ++ src/aio/aio_suspend.c | 4 +- src/internal/pthread_impl.h | 2 + src/mman/mprotect.c | 4 +- src/network/res_mkquery.c | 4 +- src/network/res_msend.c | 4 +- src/sched/thrd_yield.c | 7 ++ src/thread/__timedwait.c | 9 +- src/thread/call_once.c | 7 ++ src/thread/cnd_broadcast.c | 10 ++ src/thread/cnd_destroy.c | 5 + src/thread/cnd_init.c | 7 ++ src/thread/cnd_signal.c | 10 ++ src/thread/cnd_timedwait.c | 14 +++ src/thread/cnd_wait.c | 10 ++ src/thread/mtx_destroy.c | 5 + src/thread/mtx_init.c | 10 ++ src/thread/mtx_lock.c | 13 +++ src/thread/mtx_timedlock.c | 18 +++ src/thread/mtx_trylock.c | 21 ++++ src/thread/mtx_unlock.c | 9 ++ src/thread/pthread_cond_timedwait.c | 12 +- src/thread/pthread_create.c | 148 ++++-------------------- src/thread/pthread_detach.c | 2 +- src/thread/pthread_exit.c | 130 +++++++++++++++++++++ src/thread/pthread_getspecific.c | 5 +- src/thread/pthread_join.c | 4 +- src/thread/pthread_key_create.c | 7 +- src/thread/pthread_mutex_lock.c | 8 +- src/thread/pthread_mutex_timedlock.c | 4 +- src/thread/pthread_mutex_trylock.c | 4 +- src/thread/pthread_mutex_unlock.c | 4 +- src/thread/pthread_once.c | 4 +- src/thread/pthread_setcancelstate.c | 4 +- src/thread/pthread_testcancel.c | 4 +- src/thread/thrd_create.c | 93 +++++++++++++++ src/thread/thrd_current.c | 11 ++ src/thread/{pthread_detach.c => thrd_detach.c} | 5 +- src/thread/thrd_equal.c | 6 + src/thread/thrd_exit.c | 10 ++ src/thread/thrd_join.c | 22 ++++ src/thread/tss_create.c | 11 ++ src/thread/tss_delete.c | 7 ++ src/thread/tss_set.c | 13 +++ src/time/__clock_gettime.c | 44 +++++++ src/time/clock_gettime.c | 41 ++----- src/time/ftime.c | 4 +- src/time/gettimeofday.c | 4 +- src/time/thrd_sleep.c | 26 +++++ src/time/timespec_get.c | 12 ++ 61 files changed, 845 insertions(+), 198 deletions(-) create mode 100644 include/threads.h create mode 100644 src/sched/thrd_yield.c create mode 100644 src/thread/call_once.c create mode 100644 src/thread/cnd_broadcast.c create mode 100644 src/thread/cnd_destroy.c create mode 100644 src/thread/cnd_init.c create mode 100644 src/thread/cnd_signal.c create mode 100644 src/thread/cnd_timedwait.c create mode 100644 src/thread/cnd_wait.c create mode 100644 src/thread/mtx_destroy.c create mode 100644 src/thread/mtx_init.c create mode 100644 src/thread/mtx_lock.c create mode 100644 src/thread/mtx_timedlock.c create mode 100644 src/thread/mtx_trylock.c create mode 100644 src/thread/mtx_unlock.c create mode 100644 src/thread/pthread_exit.c create mode 100644 src/thread/thrd_create.c create mode 100644 src/thread/thrd_current.c copy src/thread/{pthread_detach.c => thrd_detach.c} (69%) create mode 100644 src/thread/thrd_equal.c create mode 100644 src/thread/thrd_exit.c create mode 100644 src/thread/thrd_join.c create mode 100644 src/thread/tss_create.c create mode 100644 src/thread/tss_delete.c create mode 100644 src/thread/tss_set.c create mode 100644 src/time/__clock_gettime.c create mode 100644 src/time/thrd_sleep.c create mode 100644 src/time/timespec_get.c -- 1.7.10.4
