[Valgrind-developers] tests/vg_regtest script running installed valgrind

[Dave N. <dc...@us...>]

We have a test group that wants to be able to test the valgrind that is 
installed in a distribution.  I was going to suggest to them that they download 
the source release from the valgrind web site and run the regression suite 
against the distribution binaries.

tests/vg_regtest has a --valgrind option for specifying a different valgrind 
(e.g. /usr/bin/valgrind) but it appears to me that VALGRIND_LIB is pretty much 
hard-wired to $tests_dir/.in_place

How about if we added a --valgrind-lib option to vg_regtest to select a 
different valgrind library directory?

I've attached a tar file(to keep my mailer from putting the patch inline and 
messing with the formatting) containing a patch to implement this.
