// Opto compiler runtime routines
//
// These are all generated from Ideal graphs.  They are called with the
// Java calling convention.  Internally they call C++.  They are made once at
// startup time and Opto compiles calls to them later.
// Things are broken up into quads: the signature they will be called with,
// the address of the generated code, the corresponding C++ code and an
// nmethod.

// The signature (returned by "xxx_Type()") is used at startup time by the
// Generator to make the generated code "xxx_Java".  Opto compiles calls
// to the generated code "xxx_Java".  When the compiled code gets executed,
// it calls the C++ code "xxx_C".  The generated nmethod is saved in the
// CodeCache.  Exception handlers use the nmethod to get the callee-save
// register OopMaps.
