Thanks to Jose Fonseca for pointing out they were missing.

There's already an implementation of pipe_barrier using
the other pipe_* primitives; just use that on Windows, too.
Now Windows passes pipe_barrier_test.
|
|
The new default implementation of pipe_condvar makes it
unnecessary.
|
|
Unfortunately compiling with these defines enabled would mean
Gallium can't run on Windows XP/2003 or older.
Todo: Need a macro to declare if we don't care about WinXP
compatibililty.

Or at least a little of it. This version will sleep
for a fixed amount of time instead of just deadlocking,
which is a slight improvement.
Also do the same thing on any unrecognized platform.

The POSIX function pthread_cond_wait can have spurious wakeups when
waiting on a condition variable.
Add a 64-bit counter that is incremented whenever the barrier becomes
full. A woken thread checks the counter. If the counter has not changed
then it has been spuriously woken and goes back to sleep. If the counter
has changed then it was properly signaled and exits the barrier.
Tested on Mac OS X.
This patch was based on ideas from Luca Barbieri.

The llvm wrapper wasn't really an OS thing.
Use lp_bld.h for now but we eventually should rename/re-prefix all the
files/functions in the gallivm/ directory.

Just a wrapper around os_log_message. Although it would probably make
more sense to be the other way around.
Also some comment fixes.

Also replace windows kernel stream with null implementation. It was
severely limited and no easy means to test it now.

Pthreads barrier functions are not available on some POSIX platforms.
