The test and set locks in boehm-gc/include/private/gc_locks.h have invalid asm
for creating the test and set locks and the current Powerpc GCC compiler
generates errors when enabling java in a bootstrap.
In addition, GCC 4.4 has added the __sync_lock_test_and_set and
__sync_lock_release builtins which abstract these functions, so the asm is not
needed for 4.4 and beyond.

Created an attachment (id=18213)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18213&action=view)
Patch to use sync builtins if we can, and fix asm constraints if we have an
older compiler

Fixed.
2009-07-17 Michael Meissner <meissner@linux.vnet.ibm.com>
PR boehm-gc/40785
* include/private/gc_locks.h (GC_test_and_set): If GCC 4.4, use
the __sync_lock_test_and _set and __sync_lock_release builtins on
the powerpc. If not GCC 4.4, fix up the constraints so that it
builds without error.
(GC_clear): Ditto.
