KCachegrind

Release Notes: This version was ported to Valgrind 3.0.x. This means support both for x86 and x86-64 applications.

Release Notes: Support for Valgrind 2.4.0 was added. Wildcards are now fully supported in function name patterns on the command line. Cache-Reuse metrics are now supported by using "--cacheuse=yes" and metric "SLoss" to locate badly aligned/layed out data structures. This shows the wasted amount of memory channel bandwidth, as it is the amount of data which was loaded into cache but never actually used.

Release Notes: The call-graph generating profiling tool and cache simulator for Valgrind was renamed to Callgrind. It now supports Valgrind up to version 2.2.0. A new --collect-systime=yes option was added for obtaining the times spent in system calls. --simulate-cache=no should be used to be able to load the data into KCachegrind. Cache simulation can be temporarily switched off to skip execution parts where no measurement is wanted. This accelerates these parts almost to real-time.

Release Notes: This release adds converter scripts for OProfile, Perl, and PHP. It allows switching between multiple visualization layouts. The call graph can be exported as a PNG. Simultaneous display of 2 event types in Call and Annotation views is possible. There are terminology corrections and bugfixes.

Release Notes: This version includes an annotated disassembler view with flow information (jump arrows), and an interactive call graph view for the call relationship around the current active function.
