+/// debuggers or other tooling; in particular, a debugger may be able to resume execution.

+///
+/// If the target platform does not have any kind of debug breakpoint instruction, this may compile
+/// to a trapping instruction (e.g. an undefined instruction) instead, or to some other form of
+/// target-specific abort that may or may not support convenient resumption.
+///
+/// The precise behavior and the precise instruction generated are not guaranteed, except that in
+/// normal execution with no debug tooling involved this will not continue executing.
+///
+/// - On x86 targets, this produces an `int3` instruction.
+/// - On aarch64 targets, this produces a `brk #0xf000` instruction.
