New targets
TimeWeaver is now also available for ARM and TriCore.
Reverse mapping
Reverse-mapping export has been implemented from trace segment costs to their originating trace input location.
Control-flow resolution
Unresolved computed control-flow transitions can now be resolved automatically using the present trace data.
Trace extraction and conversion
- TimeWeaver now supports more trace formats, as well as traces executed in a 64-bit address space.
- The trace extraction is faster and generalized across all trace formats.
- Improved extraction for traces of preemptive software.
- Improved handling of interrupts.
- The trace converter now complains if timestamps are too coarse to get usable results.
- PowerPC: fixed handling of the
iselinstruction for Lauterbach NEXUS export traces.
Graphs
- Updated look and feel of the trace segments distribution and survival graph.
- The call and control-flow graph now includes trace statistics for each edge and analysis context.
Statistics
- Raw trace data can now be exported for further processing from trace segments statistics view.
- The trace segment view now provides the calling context for each trace segment.
