intrinsic here, you must also define its name // and signature as members of the VM symbols. The VM symbols for // the intrinsic name and signature may be defined above. // // Because the VM_SYMBOLS_DO macro makes reference to VM_INTRINSICS_DO, // you can also define an intrinsic's name and/or signature locally to the // intrinsic, if this makes sense. (It often does make sense.) // // For example: // do_intrinsic(_foo, java_lang_Object, foo_name, foo_signature, F_xx) // do_name( foo_name, "foo") // do_signature(foo_signature, "()F") // klass = vmSymbols::java_lang_Object() // name = vmSymbols::foo_name() // signature = vmSymbols::foo_signature() // // The name and/or signature might be a "well known" symbol // like "equal" or "()I", in which case there will be no local // re-definition of the symbol. // // The do_class, do_name, and do_signature calls are all used for the // same purpose: Define yet another VM symbol. They could all be merged // into a common 'do_symbol' call, but it seems useful to record our // intentions here about kinds of symbols (class vs. name vs. signature). // // The F_xx is one of the Flags enum; see below. // // for Emacs: (let ((c-backslash-column 120) (c-backslash-max-column 120)) (c-backslash-region (point) (point-max) nil t)) #define VM_INTRINSICS_DO(do_intrinsic, do_class,
