If you look at it, you will see that we list a bunch of tools that
produce valgrind output that we are not interested in having show up on
the CMake dashboard.
(For example, /usr/bin/gcc and /usr/bin/c++ are in the list...)
Then, we pass that to valgrind with the
--trace-children-skip=${valgrind_skip} command line flag.
Here's the catch: that's a custom build of valgrind that we have on that
machine that understands this flag. I think Bill Hoffman developed the
patch for that behavior and tried to submit it up to valgrind upstream,
but there was much discussion and no action, if I recall correctly.
The patch has been accepted and is in valgrind. It is a slight
different format but does the same thing. So, an SVN valgrind will have
the new flag. The other thing to note is that this stops all
processing after that. So, for example since make will call cmake, we
allow make to be valgrind processed, and just add the suppression stuff
I mentioned in my other email.
Maybe Bill could chime in, or you could take up the question on
valgrind's mailing list....?
No need to go on the valgrind list, should be there now. I have not
tested and really do need to upgrade our valgrind to try the official
version of this feature...
