/* Return a teardown handle when any backend stores registration state.
* A NULL result is valid when publication succeeded only through backends
* with no unregister step, such as perf map output.
/* Publish JIT code to optional tooling backends.
*
* The return value is a backend-specific deregistration handle, not a
* success/failure indicator. NULL means there is nothing to unregister later:
* perf does not need a handle, and GDB/GNU backtrace registration failures
* are intentionally non-fatal because tooling support must not make JIT
* compilation fail.
