Dynamic program analysis with Valgrind

Valgrind is a framework for dynamic program analysis. The most usefull tools are

• The callgraph generator Callgrind.

  Which can be called via

  valgrind --tool=callgrind program
  

  The output file can be analysed with KCachegrind. In order to dump intermediate results call

  callgrind_control -d
  

• The memory error detector Memcheck.

  Which can be called via

  valgrind --suppressions=$ROOTSYS/etc/valgrind-root.supp program
  

  The suppression file suppresses false positive hits from ROOT. The output can be analysed with Valkyrie.
