X-Git-Tag: svn/VALGRIND_3_11_0~471
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=31e81facbe3e15940bcd03c80761eeb3b9b4d9cb;p=thirdparty%2Fvalgrind.git

Add some stats to helgrind stats:
* nr of client malloc-ed blocks
* how many OldRef helgrind has, and the distribution
  of these OldRef according to the nr of accs they have
