marcel e381861265 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).		2003-06-27 06:15:13 +00:00
