42 // nmethod.

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
