PETE

PETE is a standalone debugging tool with tracing, partial trace exploration, and CFG recovery and visualization features. The main features are:

GUI application with debugger-style interface. PETE is a standalone GUI application similar to a debugger. Its trace and debug navigation controls are similar to those of a debugger (Step Into, Step Over, Run to Cursor, Return to Top-level, etc) and include additional rewinding primitives that allow review of executed instructions and limited review of prior execution state (Step Backwards Into/Over, etc.)
Tracing capabilities. PETE can collect traces while debugging an application. Traces can be single- or multi-threaded, and optionally include context information at each basic block. Two types of traces are supported: compressed wpp traces with no context information, and full-context traces that contain a certain amount of context at each point along the trace. PETE is designed to scale to very large traces.
Trace Queries. Many advanced queries are possible given enough context, such as finding the last or next instruction to access a certain register, the last or next call to a specific function, or defining and skipping (stepping over) whole patterns of code.
Partial Trace Exploration. At any breakpoint, PETE provides queries on the trace accumulated up to that point.
Disassembly View. In debugging mode, PETE shows a built-in disassembled view of the application being debugged. The disassembly is typically annotated with symbolic information, such as exports and PDB/debug symbols if such information exists, as well as comments derived from internal information that PETE keeps about system code and variables.
Call Stack. In debugging mode, PETE optionally shows a view of the call stack.
Trace View. In exploration mode, at any point, PETE shows a disassembled view of the trace collected up to that point. The trace view may be annotated with symbolic information (if such information exists). Entries in the trace view may be shown or elided, either manually or automatically depending on PETE's persistent settings.
Integration with Code Visualization Tools. In trace exploration mode, PETE can make use of either its built-in disassembly viewer, or it can work together with a capable back-end application such as IDA Pro or CodeSurfer^®/x86 to show trace points in context (in their respective binary modules). The back-end being used can be changed at runtime as many times as necessary.
Platform. PETE is a Windows application.

The tool's primary audience consists of developers and reverse engineers.
