The idea is to have a series of passes where each pass specializes in extracting certain information about the trace. Some examples of potential passes include: identifying functions, identifying loops, or a more general purpose such as identifying long sequences of instructions that are repeated (i.e. Basic Super Block). Below you will find a description of each pass currently implemented in lldb. @@ -34,11 +29,6 @@ A *pass* is applied to a *layer* to extract useful information (summarization) a A “basic super block” is the longest sequence of blocks that always occur in the same order.
