This is supported on AArch64 only.

Inserts a breakpoint instruction.

val is a compile-time constant integer in range [0, 255].

The breakpoint instruction inserted is:

Safety

If val is out-of-range the behavior is undefined.

Note

The current implementation only accepts values in range [0, 255] - if the value is out-of-range the behavior is undefined.
