- 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 git-svn-id: svn://svn.valgrind.org/valgrind/trunk@7346
