TimeWeaver release 18.04

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 isel instruction 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.
