* Fix div0 bug in r_bp_getbytes() * Show 'enabled' / 'disabled' attribute of breakpoints * Implement dbg_read and dbg_write callbacks for r_debug - Added r_debug_set_io() to setup the IO for r_debug * 'db' command can now add and remove breakpoints - Not yet written into memory. only managed
r_debug
=======
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)
