480a2816f2 Add #defines to make use of libc stubs for pthread_cond_wait() and 
pthread_cond_timedwait().

XXX as noted in the comments, in the situations where these are
useful, they should never be called in a single-threaded
process. Perhaps they should die rather than return 0.

Addresses xsrc/28630.

cb9ebec1e2 Correctly return ETIMEDOUT when the absolute time is in the past, in 
the nonthreaded case. Fixes, and fix from, PR lib/25961.

0eaa8971b7 Use CPP macros to cause many libpthread functions used by applications 
to be transformed into the do-nothing-when-libpthread-isn't-linked libc
stub names. This will permit library code that uses <pthread.h> and pthread
functions "defensively" to not need to link against libpthread and not need
to be patched to the threadlib.h API.

45204d9ceb Punt to setcontext() system call if the PSL_T bit (single-step trap) 
is set, so that the single-step trap happens in the thread's context
and not in the middle of _setcontext_u.

XXX might be able to do something here with iret, too, but it needs
more testing.

2b4ccae3e9 Remove pt_blockuc. If the debugger attempts to muck with the state of a 
blocked thread, return an error; this should be done through ptrace(2).

spurious wakeups (such as those caused by gdb) should not cause
nanosleep to return prematurely.

c6736a59b3 redo the fix for PR 26392 differently: instead of changing the stack bounds 
for the initial stack, just change the initial thread's pt_uc to point to
the opposite end of the stack (away from the argv, environment, etc).

6b2b9c625f - fix pthread_detach with an already exit'ed thread. 
namely, put the thread to deadqueue rather than just leaking it.
- fix a race between pthread_detach/join and pthread_exit,
  which also causes dead thread leaks.

8bf7374bcf In cond_wait() and cond_timedwait(), do the ERRORCHECK testing of the 
waiters list in all cases, not just on cancellation; there are other
sources of spurious wakeups, such as single-stepping in the debugger.

regress/lib/libpthread/conddestroy1 now passes.

e348d7e175 add hppa MD libpthread bits. translated from MIPS. 2004-07-19 03:39:02 +00:00
chs
94a458cedd enhance MI pthreads code to support hppa: 
- statically initialize all global spin locks.  on hppa, 0 means
   the lock is held, so leaving them with the default value doesn't work.
 - compare functions pointers using a function-pointer type rather than
   an integral type.  on hppa, function pointers may be indirect,
   so we need to trigger gcc to emit calls to the function-pointer
   canonicalization routines in the millicode.
 - on hppa the stack grows up, so handle that using the STACK_* macros.

47513cedb9 If the sleep sleeps for its full time and rmtp is non-NULL, clear it; 
sleep(3) expects this, even though it's not a documented property of
nanosleep().

Fixes a problem where sleep() in a threaded program would return
nonzero even on success.
