jmp_buf, add a compile time assert to catch this kind of divergence
in the C code.
Move the fixed "%npc = %pc + 4" computation to longjmp, this frees
the sigcontext sc_npc value. Use this space to save the savemask
for siglongjmp (we have run out of space behind the globals).
Fixes the tests/lib/libc/setjmp/t_threadjmp tests, and also hopefully
fixes PR port-sparc64/44902.
- remove RF_DECLARE_EXTERN_MUTEX and RF_DECLARE_STATIC_MUTEX, the qualifier
can be provided at the use point with the normal define
- rename the *LGMGR_MUTEX() macros to *mutex2() names, and add some more
defines for use:
rf_declare_mutex2()
rf_declare_cond2()
rf_lock_mutex2()
rf_unlock_mutex2()
rf_init_mutex2()
rf_destroy_mutex2()
rf_init_cond2()
rf_destroy_cond2()
rf_wait_cond2()
rf_signal_cond2()
rf_broadcast_cond2()
- use the new names for the configureMutex(), which previous used some combo
of direct mutex* calls and macros
- convert the node_queue to use a mutex/cv combo
- in rf_ShutdownEngine() and DAGExecutionThread(), also signal the former from
the latter when it is done and about to exit
- convert iodone_lock to use the new macros
- Replace the ugly sync loop in ffs_full_fsync() and ffs_vfs_fsync() with
vflushbuf(). This loop is a relic of softdeps and not needed anymore.
- Add ffs_spec_fsync() for device nodes on ffs file systems that calls
spec_fsync() like all other file systems do and then updates the ctime.
Discussed on tech-kern.
