A new drd version is available at the following location: http://home.euphonynet.be/bvassche/valgrind/valgrind-6618-drd-2007-02-27.patch.gz Changes compared to version 2007-02-22: - Eliminated AMD64 false positives -- drd now behaves consistently on X86 and AMD64. - Started optimizing the bitmap implementation in drd -- drd now works several times faster for clients with 10 threads or more. More work has to be done in this area however. (Only bm_clear() and bm_has_access() have been optimized. According to cachegrind, VG_(OSet_Next)() is now the function that consumes most CPU cycles.) - The soft link in .in_place/drd/default.supp is now created automatically -- drd's default suppression file is not yet automatically installed in the installation directory. - Specifying Valgrind's option -v no longer triggers a crash in drd. - Defined new pthread_pre_create tracking function. - New command-line option: --trace-suppression. Most important known bugs: - drd is soon killed by the OOM handler when started with bigger clients. - drd/default.supp has to be installed manually in the installation dir. An example of how the patch can be applied and the regression tests can be run: svn co svn://svn.valgrind.org/valgrind/trunk valgrind cd valgrind gzip -cd ../valgrind-6618-drd-2007-02-27.patch.gz | patch -p0 - ./autogen.sh ./configure --prefix=$PWD/inst make -s make -s check chmod a+x drd/tests/filter_stderr perl tests/vg_regtest drd -- Regards, Bart Van Assche. |
