36 // Opto compiler runtime routines
37 //
38 // These are all generated from Ideal graphs. They are called with the
39 // Java calling convention. Internally they call C++. They are made once at
40 // startup time and Opto compiles calls to them later.
41 // Things are broken up into quads: the signature they will be called with,
42 // the address of the generated code, the corresponding C++ code and an
43 // nmethod.
44
45 // The signature (returned by "xxx_Type()") is used at startup time by the
46 // Generator to make the generated code "xxx_Java". Opto compiles calls
47 // to the generated code "xxx_Java". When the compiled code gets executed,
48 // it calls the C++ code "xxx_C". The generated nmethod is saved in the
49 // CodeCache. Exception handlers use the nmethod to get the callee-save
50 // register OopMaps.
51 //
52 // Please ensure the return type of the runtime call matches its signature,
53 // even if the return value is unused. This is crucial for correct handling
54 // of runtime calls that return an oop and may trigger deoptimization
55 // on return. See rematerialize_objects() in deoptimization.cpp.
