/* The following define instruction sequences that will cause ARM
|
||
cpu's to take an undefined instruction trap. These are used to
|
||
signal a breakpoint to GDB.
|
||
|
||
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, RISC iX,
|
||
and 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
|
||
fashion. */
