lib/libpthread/arch/ia64/ia64 context.S
Log:
Implement _ia64_save_context() and _ia64_restore_context(). Both
functions are derived from the swapctx() and restorectx() (resp)
from sys/ia64/ia64/context.s. The code is expected to be 99%
correct, but has not yet been tested.
Note that with these functions operating on mcontext_t, we also
created the foundation upon which we can implement getcontext(2)
and setcontext(2) replacements. It's not guaranteed that the use
of these syscalls and _ia64_{save|restore}_context() on the same
uicontext_t is actually going to work. Replacing the syscalls is
now trivially achieved.
This commit completes the ia64 port of libpthread itself (modulo
testing and bugfixes).
