pancake ff8a7ecd58 * cleanup the TODO file * Added cfg.debug config variable * Fix the basic stuff for r.dbg.reg api integrated with core * Failover into the plugin breakpoint implementation to support non memory breakpoints like API ones or hardware ones * Added initial non-working version of the gdbwrap debug plugin - We need to design an IO plugin for gdbwrap too (or a way to change the IO based on the debug plugin)		2009-04-17 11:42:45 +00:00

=======

  Debugger API for radare2


We need to connect multiple pieces...

debugger engine: vm, qemu, bochs, ptrace, mach, w32dbg...

controlflow commands: (should be splitted in two layers)

 - continue -- low level
 - step     -- low level
 - trace   --- high level one
 - ...

 the control flow commands depend on other stuff to decide
 how to work..this is for example if the arch doesnt supports
 continuation, we should provide a step based continue. The
 same when a watchpoint is activated and the arch didnt
 supports hardware regs for this purpose.

We also need a load/store/dump/restore functions to move the
program from one engine to another (ptrace -> qemu).. we should
provide a way for all this operations between them.

[continue]
    |--- check if bp api allows us to continue or we should step into..
    |--- check if debug plugin supports continue

[getregs]
    |--- r_reg give us a list of registers
    |    - dr (show bitsize debug registers) // 32 by default
    |    - dr 32 (show 32 bit debug registers) // depends on size
    |    - dr eax (show 'eax' register value)
    |    - dr al  (show 8bit register 'al')
    |    - dr eax=33 (set 'eax' register value)
