Eric van Gyzen	07f29d9f76	Remove old spinlock_debug code from libc ... This no longer seems useful. Remove it. This was prompted by a "cast discards volatile qualifier" warning in libthr when WARNS=6.

Daniel Eischen	82358b1b5a	Remove #include of spinlock.h from libc_private.h. Declare spinlocks as ... struct _spinlock. Keep the typedef in for now; another set of changes may come around to clean up consumers of spinlocks. Requested by: bde	2003-11-05 18:17:30 +00:00
Jeff Roberson	cc3521d660	- Define a _spinunlock() function so that threading implementations may do ... more complicated things than just setting the lock to 0. - Implement stubs for this function in libc and the two threading libraries that are currently in the tree.	2003-03-26 04:02:24 +00:00

John Birrell	f374bfcd3c	Implement compile time debug support for spinlocks. ... Simplify the atomic lock prototype, removing the lock value. Delete the unlock prototypes that are not required.	1998-06-09 08:28:49 +00:00
John Birrell	f1daac6f22	In a threaded library, expect the lock field to be declared volatile, ... so provide function prototypes that respect that, avoiding a gcc warning that `volatile' is being thrown away.	1998-05-05 21:46:30 +00:00
John Birrell	0a31d34120	Add a private (to libc, libc_r and libpthread) header file containing ... prototypes for the spinlock functions that will be used for thread locks. libc will have stubs declared with weak symbols. libpthread and libc_r will have functions that really do something.	1998-03-09 05:05:32 +00:00
