Hi Matthew :)

arm_remote_breakpoint_from_pc (in gdb/arm-tdep.c around line 5121)
contains the following comment:

 if (arm_pc_is_thumb (*pcptr) && *kindptr == 4)
   /* The documented magic value for a 32-bit Thumb-2 breakpoint, so
      that this is not confused with a 32-bit ARM breakpoint.  */
   *kindptr = 3;

I can't find the documentation which gives the magic value.  Could
someone direct me to it please?

I guess this is what that comment refers to: http://sourceware.org/gdb/current/onlinedocs/gdb/Architecture_002dSpecific-Protocol-Details.html
