 37 // These are all generated from Ideal graphs.  They are called with the
 38 // Java calling convention.  Internally they call C++.  They are made once at
 39 // startup time and Opto compiles calls to them later.
 40 // Things are broken up into quads: the signature they will be called with,
 41 // the address of the generated code, the corresponding C++ code and an
 42 // nmethod.
 43 
 44 // The signature (returned by "xxx_Type()") is used at startup time by the
 45 // Generator to make the generated code "xxx_Java".  Opto compiles calls
 46 // to the generated code "xxx_Java".  When the compiled code gets executed,
 47 // it calls the C++ code "xxx_C".  The generated nmethod is saved in the
 48 // CodeCache.  Exception handlers use the nmethod to get the callee-save
 49 // register OopMaps.
