Subject: Fixed suppression reading so that you can specify up to four "fun:" or "obj:"
X-Git-Tag: svn/VALGRIND_2_0_0~156
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=96c3404d77ccc6e1e2562c1fd1be78313ca5c0ea;p=thirdparty%2Fvalgrind.git

Fixed suppression reading so that you can specify up to four "fun:" or "obj:"
lines (it was 3 due to a bug).

Also removed VG_(get_suppressions)() which wasn't being used, and changed
VG_(exitcode) to an Int, as it should be.
