H A Dhtr.rst1 Hierarchical Trace Representation (HTR)
3 The humongous amount of data processor traces like the ones obtained with Intel PT contain is not digestible to humans in its raw form. Given this, it is useful to summarize these massive traces by extracting useful information. Hierarchical Trace Representation (HTR) is the way lldb represents a summarized trace internally. HTR efficiently stores trace data and allows the trace data to be transformed in a way akin to compiler passes.
14 metadata is only stored for instructions that are of interest, not every instruction in the trace. HTR contains a
19 a block layer. HTR contains one or more block layers.
