Data-race detection algorithm
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- Implement segment merging, such that the number of segments per thread
- remains limited even when there is no synchronization between threads.
-- Add locking order checking.
-- Discuss on the Valgrind mailing list how to make it possible to call
- POSIX thread synchronization primitives from client code (drd_intercepts.c)
- without triggering Valgrind's redirection mechanism.
- Make sure -v works again with exp-drd.
+- Add locking order checking.
- Continue the discussion on the Valgrind mailing list about docbook and
'make dist'.
-- Continue the discussion on the Valgrind mailing list about -Wformat.
-- Enable format string checking for DRD during compilation.
-- Propose to modify tl_assert() / vg_assert() such that it uses
- __builtin_expect.
- Explain on the Valgrind mailing list the difference between a bus lock
and acquire / release labels.
- Add configure tests for the name of the 'kind' member in pthread_mutex_t.
- Find out why a race is reported on std::string::string(std::string const&)
(stc test case 16).
-- Find out why no races are reported on matinv_openmp.c when "private(k)" is
- removed.
- Add support for objects that are shared over threads and that use reference
counting, e.g. std::string -- no races should be reported on the reference
count.

- Find out why no line number or variable name information is printed for
races detected in parallel sections of OpenMP programs. An example:
./vg-in-place --tool=exp-drd exp-drd/tests/omp_prime 4 -t 2
-- Find a way for suppressing races reported on _IO_2_1_stdout. This race is
- triggered by calling printf() from more than one thread. Examples (AMD64):
- ./vg-in-place --tool=exp-drd exp-drd/tests/tc21_pthonce
- Find out why 'matinv 400' runs faster in 32-bit mode than in 64-bit mode
on the same CPU.
- testing on PPC and AIX (current implementation is only tested on X86 and
AMD64).
- Convert the array in drd_thread.c with thread information into an OSet.
-- Performance testing and tuning.
-- Optimize run time of the following test case:
- ./vg-in-place --tool=exp-drd exp-drd/tests/matinv 100
+- Performance testing and tuning, a.o. for kate / knode / open office / matinv.
