2024-10-13Read instructions directly from program memoryTheofilos Augoustis2-19/+32
Instead of loading an executable file and disassembling instructions from there, load instructions directly from the concrete execution's memory. This allows symbolic tracing to work for non-statically compiled executables as well as JIT-compiled code.
2024-07-28Enable Focaccia's logging in capture_transforms.pyTheofilos Augoustis2-11/+10
Disable Miasm's disassembly logger by default. Enable Focaccia's symbolic execution logger. Also refactor envp construction to use the `utils.get_envp` function.
2024-07-12Add support for aarch64Theofilos Augoustis10-88/+293
- Implement an architecture description for aarch64 - Add endianness information to the `Arch` class. - Move conversion from flags register to logical flag values from the calling code to the concrete targets (LLDB and GDB), which is the only point where we (have to) deal in flags registers. - Handle assembly/disassembly errors in serialization of SymbolicTransform - Move ProgramState's `arch` attribute into ReadableProgramState.

2024-02-19Make symbolic equations more symbolicTheofilos Augoustis10-198/+413
Reduce the impact of concrete guidance on the process of calculating an instruction's symbolic equation. The resulting equations will contain less assumptions about the concrete state and thus be more generic.

2024-02-02Add ReadableProgramState interfaceTheofilos Augoustis4-71/+97
It often occurs that a function only wants to read values from a ProgramState, but not write them. The new interface ReadableProgramState captures this need.
