1 what is working:

2 - runs chrome + sel_ldr + nexe

3 - intercepts nexe before it started

4 - loading address of nexe is passed to debugger

5 - can insert upto 4 breakpoints in nexe

6 - stops nexe when breakpoint is hit

7 - can continue from breakpoint

8 - can read and write registers and memory

9 - can catch division by zero and zero pointer access

10

11 what is not implemented or have some uglinness:

12 - single step is not implemented (but is possible)

13 - break-in is not implemented

14 - hardware single step is not working (due to NaCl sandbox)

15 - software breakpoints are not working (due to NaCl sandbox)

16 - breakpoints are implemented with HW breakpoints (registers D0-D7),

17 limiting them to 4 max

18 - breakpoints can be set on jump instructions, but breakpoint could be lost

19 after continue from breakpoint

20 - user has to specify length of instruction on which he wants breakpoint to be

21 set

22 - debugger has to be run from sudo

23 - chrome has to be started with --disable-breakpad

24 - code is ugly

25 - debug helpers that go into TCB are not yet ready for CL & commit
