ftmemsim-valgrind/exp-drd/drd_intercepts.c
Julian Seward 02c9054a2b drd changes (Bart Van Assche) 
- The exp-drd regression tests now run without producing assertion
failures and without hanging on Red Hat 7.3. It doesn't make sense
however to run exp-drd on Red Hat 7.3 -- while exp-drd works fine with
the NPTL, more work would be required to make exp-drd work with
linuxthreads.
- Converted several tl_assert() calls into error messages.
- Added a regression test called pth_barrier, which tests whether data
races are detected in a program that uses barriers. The output exp-drd
produces for this test program is not yet correct however.
- Updated exp-drd/TODO.txt.

ALL THE CODE IN THIS FILE RUNS ON THE SIMULATED CPU.
These functions are not called directly - they're the targets of code
redirection or load notifications (see pub_core_redir.h for info).
They're named weirdly so that the intercept code can find them when the
shared object is initially loaded.
Note that this filename has the "drd_" prefix because it can appear
in stack traces, and the "drd_" makes it a little clearer that it
originates from Valgrind.
