d6bb5c34d0 DRD now prints where a mutex appeared for the first time in addition to 
the mutex address when an error message is printed for condition
variables.

806d5abe6d Some time ago reporting sending POSIX signals where the mutex associated 
with the signal via pthread_cond_wait()/pthread_cond_timedwait() was
disabled. Reenabled this report, made it configurable, and added a
regression test for the new command line option.

1c0e43670f Added support for POSIX reader-writer locks. Modified exp-drd/tests/filter-stderr such that i386 and AMD64 now generate the same output. Removed *.stderr.exp2 files. Added section that explains differences between LinuxThreads and NPTL to exp-drd/docs/README.txt. Made error message about LinuxThreads more clear. Made error messages more uniform.

0336cdffbb Modified drd client requests such that the mutex type can be passed from the intercepts to the tool. An error message is now printed in case a locked mutex is destroyed and in case a thread exits while it holds a lock on a mutex. Changed format of mutex error messages. Added recursive_mutex regression test. Fixed autogen warnings in exp-drd/tests/Makefile.am.

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
