From 268fac6919ef673094e50e2d944d09f017f5ad33 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 4 Feb 2009 00:26:22 +0100 Subject: [PATCH] Add a script to coalesce the valgrind outputs After running the valgrind tests with GIT_TEST_TREE=t, the test output is in the test-results/$TEST.out files. Call ./valgrind/analyze.sh in $GIT_ROOT/t/ to group the valgrind errors by backtrace.
