because there's no handler for it.
(LCOUNT, oldmask): Remove.
(lwpEntryPoint): Don't initialize oldmask. Should have been done in
lwpInitSystem() anyway.
machine-dependencies:
(lwpNewContext): New, factored out of lwpCreate().
(lwpSwitchContext): New, factored out of lwpReschedule().
(LWP_EXTRASTACK, STKALIGN, lwpInitContext, lwpSave, lwpRestore): Move
to arch.c. Remove for UCONTEXT, else static linkage unless macro or
AIX32.
(lwpReschedule): Skip lwpStatus() when not actually switching.
(LwpStackGrowsDown): New.
(lwpInitSystem): Initialize it.
(lwpStackCheck, lwpStackCheckUsed): Use it.
ustack, usize.
(lwpCreate): Initialize them.
(lwpStackCheckInit, lwpStackCheck, lwpStackCheckUsed): Rewrite using
them. lwpStackCheckUsed() was off by LWP_REDZONE when stack grows
down.
(lwpDestroy): Don't bother to clear memory to be freed.
complete declaration to src/lib/lwp/lwpint.h.
(lwpQueue): Move to src/lib/lwp/lwpint.h.
(empth_main, empth_flags): New.
(empth_init): Initialize them.
(empth_create, empth_exit): Use them instead of lwpProc members.
an odd case where signals were not catched when debugging.
(main, empth_start): Using sa_handler with SA_SIGINFO is wrong.
Simply don't set SA_SIGINFO; the additional signal information is not
used anyway.
between headers. Code is now fully prototyped and compiles cleanly
with gcc -Wstrict-prototypes -Wmissing-prototypes -Wnested-externs
-Wredundant-decls. Closes#723788.
thread entrypoints:
(lwpSelect, shutdown_sequence): Parameters didn't match thread entry
point prototype.
(lwpEntryPoint): Arguments didn't match thread entry point prototype.
Change linkage of functions without prototype declaration to static
where possible.
Remove some superflous declarations, replace others by suitable
includes.
