| 26 // Opto compiler runtime routines | |
| 27 // | |
| 28 // These are all generated from Ideal graphs. They are called with the | |
| 29 // Java calling convention. Internally they call C++. They are made once at | |
| 30 // startup time and Opto compiles calls to them later. | |
| 31 // Things are broken up into quads: the signature they will be called with, | |
| 32 // the address of the generated code, the corresponding C++ code and an | |
| 33 // nmethod. | |
| 34 | |
| 35 // The signature (returned by "xxx_Type()") is used at startup time by the | |
| 36 // Generator to make the generated code "xxx_Java". Opto compiles calls | |
| 37 // to the generated code "xxx_Java". When the compiled code gets executed, | |
| 38 // it calls the C++ code "xxx_C". The generated nmethod is saved in the | |
| 39 // CodeCache. Exception handlers use the nmethod to get the callee-save | |
| 40 // register OopMaps. | |
