FWIW, at Transmeta we had a local extension to gcc called
"__builtin_not_reached()" which we used to tell gcc that an assembly
statement would terminate the control flow.

Another useful extension was a variant of __builtin_trap() which would
create a dummy ELF relocation for the trapping instruction with a target.
