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)) // // // There are two types of intrinsic methods: (1) Library intrinsics and (2) bytecode intrinsics. // // (1) A library intrinsic method may be replaced with hand-crafted assembly code, // with hand-crafted compiler IR, or with a combination of the two. The semantics // of the replacement code may differ from the semantics of the replaced code. // // (2) Bytecode intrinsic methods are not replaced by special code, but they are // treated in some other special way by the compiler. For example, the compiler // may delay inlining for some String-related intrinsic methods (e.g., some methods // defined in the StringBuilder and StringBuffer classes, see // Compile::should_delay_string_inlining() for more details). // // Due to the difference between the semantics of an intrinsic method as defined // in the (Java) source code and the semantics of the method as defined // by the code in the VM, intrinsic methods must be explicitly marked. // // Intrinsic methods are marked by the jdk.internal.vm.annotation.IntrinsicCandidate // annotation. If CheckIntrinsics is enabled, the VM performs the following // checks when a class C is loaded: (1) all intrinsics defined by the VM for // class C are present in the loaded class file and are marked; // (2) an intrinsic is defined by the VM for all marked methods of class C; // (3) check for orphan methods in class C (i.e., methods for which the VM // declares an intrinsic but that are not declared for the loaded class C. // Check (3) is available only in debug builds. // // If a mismatch is detected for a method, the VM behaves differently depending // on the type of build. A fastdebug build exits and reports an error on a mismatch. // A product build will not replace an unmarked library intrinsic method with // hand-crafted code, that is, unmarked library intrinsics are treated as ordinary // methods in a product build. The special treatment of a bytecode intrinsic method // persists even if the method not marked. // // When adding an intrinsic for a method, please make sure to appropriately // annotate the method in the source code. The list below contains all // library intrinsics followed by bytecode intrinsics. Please also make sure to // add the declaration of the intrinsic to the appropriate section of the list. #define VM_INTRINSICS_DO(do_intrinsic, do_class, do_name, do_signature, do_alias) \/* (1) Library intrinsics */ \ "hashCode" ) \\"getClass" ) \"clone" ) \"notify" ) \RN) \"notifyAll" ) \/* Math & StrictMath intrinsics are defined in terms of just a few signatures: */ \ "java/lang/Math" ) \"java/lang/StrictMath" ) \"(DD)D" ) \"(DDD)D" ) \"(FF)F" ) \"(FFF)F" ) \"(II)I" ) \"(JJ)I" ) \"(JJ)J" ) \/* here are the math names, all together: */ \ "abs" ) do_name(sin_name,"sin" ) do_name(cos_name,"cos" ) \"tan" ) do_name(atan2_name,"atan2" ) do_name(sqrt_name,"sqrt" ) \"log" ) do_name(log10_name,"log10" ) do_name(pow_name,"pow" ) \"exp" ) do_name(min_name,"min" ) do_name(max_name,"max" ) \"floor" ) do_name(ceil_name, "ceil" ) do_name(rint_name, "rint" ) \"round" ) \"addExact" ) \"decrementExact" ) \"incrementExact" ) \"multiplyExact" ) \"multiplyHigh" ) \"unsignedMultiplyHigh" ) \"negateExact" ) \"subtractExact" ) \"fma" ) \"copySign" ) \"signum" ) \"expand" ) \re, F_S) \ture, F_S) \re, F_S) \ture, F_S) \e, F_S) \ure, F_S) \, F_S) \2_long_signature, F_S) \) \_S) \e, F_S) \ure, F_S) \S) \\/* StrictMath intrinsics, similar to what we have in Math. */ \ _S) \_S) \, F_S) \, F_S) \/* Special flavor of dsqrt intrinsic to handle the "native" method in StrictMath.
