486 // Here are all the intrinsics known to the runtime and the CI.
487 // Each intrinsic consists of a public enum name (like _hashCode),
488 // followed by a specification of its klass, name, and signature:
489 // template(<id>, <klass>, <name>, <sig>, <FCODE>)
490 //
491 // If you add an intrinsic here, you must also define its name
492 // and signature as members of the VM symbols. The VM symbols for
493 // the intrinsic name and signature may be defined above.
494 //
495 // Because the VM_SYMBOLS_DO macro makes reference to VM_INTRINSICS_DO,
496 // you can also define an intrinsic's name and/or signature locally to the
497 // intrinsic, if this makes sense. (It often does make sense.)
498 //
499 // For example:
500 // do_intrinsic(_foo, java_lang_Object, foo_name, foo_signature, F_xx)
501 // do_name( foo_name, "foo")
502 // do_signature(foo_signature, "()F")
503 // klass = vmSymbols::java_lang_Object()
504 // name = vmSymbols::foo_name()
505 // signature = vmSymbols::foo_signature()
506 //
507 // The name and/or signature might be a "well known" symbol
508 // like "equal" or "()I", in which case there will be no local
509 // re-definition of the symbol.
510 //
511 // The do_class, do_name, and do_signature calls are all used for the
512 // same purpose: Define yet another VM symbol. They could all be merged
513 // into a common 'do_symbol' call, but it seems useful to record our
514 // intentions here about kinds of symbols (class vs. name vs. signature).
515 //
516 // The F_xx is one of the Flags enum; see below.
517 //
518 // for Emacs: (let ((c-backslash-column 120) (c-backslash-max-column 120)) (c-backslash-region (point) (point-max) nil t))
