/* Return pointer to ARGBUF given ptr to SCACHE. */
#define SEM_ARGBUF(sem_arg) (& (sem_arg) -> argbuf)
-/* There are several styles of engines, all generally supported by the
- same code:
-
- WITH_SCACHE && WITH_SCACHE_PBB - pseudo-basic-block scaching
- WITH_SCACHE && !WITH_SCACHE_PBB - scaching on an insn by insn basis
- !WITH_SCACHE - simple engine: fetch an insn, execute an insn
-
- ??? The !WITH_SCACHE case can also be broken up into two flavours:
- extract the fields of the insn into an ARGBUF struct, or defer the
- extraction to the semantic handler. The WITH_SCACHE case always
- extracts the fields into an ARGBUF struct. */
