- r_debug_ptrace is now static by default * Some code cleanup and warnings removal * Added hg-utils.mk and MKPLUGINS directive in user-config * Initial implementation of dbg_gdb r_debug plugin - Import ERESI's libgdbwrap from r1 * Add some missing files (asm/p/fastcall_mips.h, core/t/ragrep2.c) * Added r_str_bool helper to get "true"/"false" from int
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)
