|
Since sigset_t no longer fits in a register, we can't pass in the
|
|
thread's initial mask so easily. Take this opportunity to simplify
|
|
the clone implementation by only accepting a single void* argument.
|
|
|
|
* linuxthreads/manager.c (__pthread_manager): Put thread vitals
|
|
in the thread struct instead of as arguments through clone.
|
|
(pthread_start_thread): Look for them there.
|
|
* linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
|
|
p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
|
|
* linuxthreads/pthread.c (pthread_initialize_manager): Revise
|
|
clone invocation.
