| 3 | | The new implementation standardizes argument passing for all calls (whether from PIR or C). Each call creates a call signature object right away, inserting arguments into the signature object from the opcode pointer or varargs list as soon as the call is made. Parameters are always extracted from a call signature object, and know nothing about the source of the call (they don't need to know what kind of environment invoked them, since all calls follow the same code path, and pass arguments the same way). NCI calls and what was previously known as PCCMETHOD calls also use the same argument passing strategy. Signature strings will be standardized on the PCC form (e.g. PI->S), for a call with a pmc and an integer argument, that returns a string result). The exception is NCI signatures, which will be left alone for now, but may be standardized later. |
