Julian Seward 22b3fe2a3e DRD updates (Bart Van Assche):
- Updated copyright statement: replaced 2006-2007 by 2006-2008.
- Added copyright statement in the files where it was missing
(drd_track.h and drd_clientreq.c)
- Eliminated dependencies on core header files -- there are no more
#include "pub_core....h" directives in the exp-drd source code.
- Added semaphore support.
- Added barrier support.
- Added pthread_mutex_timedlock() support.
- Stack depth of stack traces printed by exp-drd can now be set via
--num-callers=...
- Added command-line option --trace-barrier=[yes|no].
- Added regression test for pthread_barrier() (matinv, a program that
performs matrix inversion).
- Added regression test sem_as_mutex, which tests whether race
detection works correctly when a semaphore is used to ensure mutual
exclusion of critical sections.
- Some of helgrind's regression tests are now used to test both
helgrind and exp-drd: tc17_sembar and tc18_semabuse.
- Cleaned up bitmap implementation code now that the const keyword has
been added to the declarations of the OSet functions.
- Cleaned up exp-drd/Makefile.am
- Updated exp-drd/TODO.txt
