d052279628 Changed the way how data races in NPTL's thread-private data on the top of the stack are ignored: instead of clearing the corresponding region in the bitmap of every thread when the stack pointer is increased, the appropriate bits in the suppression bitmap are set at thread creation time.

44d59037f3 Removed --trace-mem which traced all memory accesses. Added support for multiple --trace-address options. A range size can now be specified to the VG_USERREQ__DRD_START_TRACE_ADDR client request. Added VG_USERREQ__DRD_STOP_TRACE_ADDR client request.

f3db559a9d Make sure no error message is printed when pthread_mutex_trylock() is called on a non-recursive mutex from the thread that holds a lock on the mutex.

bd1e6d9da1 Added support for OpenMP barriers -- if libgomp.so has been built with debug information. More in general, added support for nested synchronization constructs.

8eb391f87d Added new command-line option --trace-rwlock. Added regression test exp-drd/tests/rwlock_race. Updated to do list. Fixed bug in vc_min(), the function that computes the elementwise minimum of two vector clocks. Fixed bug in thread_update_danger_set(). Fixed recently introduced bug in mutex code with regard to vector clock combining.

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.

f9bbc5bf9a Added command-line option --trace-clientobj. Renamed drd_clientobj* functions into clientobj*. Moved some code from drd_main.c into the drd_mutex.c/drd_cond.c/drd_semaphore.c.

1a03c31785 Eliminated per-thread start/stop recording mechanism, which should make DRD a little bit faster. malloc()/free() is now intercepted on all platforms instead of just on i386.

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.

994193f9bb Regtest/stability changes for drd (Bart Van Assche) 
- Fix helgrind/tests/tc18_semabuse.c on glibc 2.7 (RedHat 8).

- Fixed a glibc 2.7 specific assertion failure in exp-drd, namely one
  that was triggered when sem_post()'s return value is not zero.

- exp-drd/test/matinv.c compiles now also on RedHat 7.3.

Note: more work will be required to get exp-drd working correctly on
RedHat 7.3.

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
