[BZ #357]
Update. 2004-09-02 Steven Munroe <sjmunroe@us.ibm.com> [BZ #357] * stdlib/tst-setcontext.c (test_stack): Added test for stack clobber. (main): Call test_stack. * sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext.S (__getcontext): Push stack frame then save parms in local frame. Improve instruction scheduling. * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext.S (__swapcontext): Likewise.

+ * sysdeps/unix/sysv/linux/internaltypes.h: Define COND_CLOCK_BITS.

+ * pthread_cond_destroy.c (__pthread_cond_destroy): Return EBUSY
+ if there are waiters not signalled yet.
+ Wait until all already signalled waiters wake up.
+ * sysdeps/pthread/pthread_cond_wait.c (__condvar_cleanup): Decrement
+ __nwaiters. If pthread_cond_destroy has been called and this is the

+ and this is the last waiter, signal pthread_cond_destroy caller.

+ clock type just from the last COND_CLOCK_BITS bits of value.
+ * pthread_cond_init.c (__pthread_cond_init): Initialize __nwaiters
+ instead of __clock, just from second bit of condattr's value.
