- Added breakpoint and code analysis plugins for bf - *mem++ != mem[0]++ - Full register get/set support - Support for step and continue-until-syscall - Work in progress breakpoint support * Added bfvm_reset() hooked to plugin->kill * Enhacements in r_core and r_debug for better debugger support - Added plugin->step_over delegate
libr.bp
=======
Breakpoint API
- Manages list of defined breakpoints
- Determines if a stop is caused by a breakpoint
- Owns a database of multiple types of breakpoints
- arch and os based ones
- Supports endianness
- r_bp_get should return a buffer and a length
- Manages conditional breakpoints expressions
- Types of breakpoints
- software (traps)
- conditional traps
- hardware (registers)
- mmu (changes page protections)
- All non-native operations are translated into evaluable expressions
by other modules. Like changing register values and so on
- Do we should place some callbacks for this kind of ops?
- We need to make this work also remotely
- r_debug can handle the remoteness of the debugger backend.
- r_io can do it also
- Watchpoints and its exception should be handled here
- watchpoint expressions should be handled by using the r_num stuff
- Hardware breakpoints require access to registers, or pid/tid
this is... the debugger backend. For those, the debugger backend
should fill a callback to manage them.
- if the debugger breakpoint handler does not manages the breakpoint
type, r_bp must do it with r_io storing and loading bp bytes.
* Do we need the plugin API to define new breakpoints and so on?
