cpu's to take an undefined instruction trap. These are used to |

|
The newer ARMv4T cpu's are capable of operating in ARM or Thumb |
modes. A different instruction is required for each mode. The ARM |
cpu's can also be big or little endian. Thus four different |
instructions are needed to support all cases. |
|
Note: ARMv4 defines several new instructions that will take the |
undefined instruction trap. ARM7TDMI is nominally ARMv4T, but does |
not in fact add the new instructions. The new undefined |
instructions in ARMv4 are all instructions that had no defined |
behaviour in earlier chips. There is no guarantee that they will |
raise an exception, but may be treated as NOP's. In practice, it |
may only safe to rely on instructions matching: |
|
3 3 2 2 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 1 1 1 |
1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 |
C C C C 0 1 1 x x x x x x x x x x x x x x x x x x x x 1 x x x x |
|
Even this may only true if the condition predicate is true. The |
following use a condition predicate of ALWAYS so it is always TRUE. |
|
There are other ways of forcing a breakpoint. ARM Linux, RisciX, |
and I suspect NetBSD will all use a software interrupt rather than |
an undefined instruction to force a trap. This can be handled by |
redefining some or all of the following in a target dependent |
