570 // Implementation of AdapterHandlerLibrary | |
571 // | |
572 // This library manages argument marshaling adapters and native wrappers. | |
573 // There are 2 flavors of adapters: I2C and C2I. | |
574 // | |
1748 | 575 // The I2C flavor takes a stock interpreted call setup, marshals the |
576 // arguments for a Java-compiled call, and jumps to Rmethod-> code()-> | |
577 // code_begin(). It is broken to call it without an nmethod assigned. | |
578 // The usual behavior is to lift any register arguments up out of the | |
579 // stack and possibly re-pack the extra arguments to be contigious. | |
580 // I2C adapters will save what the interpreter's stack pointer will be | |
581 // after arguments are popped, then adjust the interpreter's frame | |
582 // size to force alignment and possibly to repack the arguments. | |
583 // After re-packing, it jumps to the compiled code start. There are | |
584 // no safepoints in this adapter code and a GC cannot happen while | |
585 // marshaling is in progress. | |
0 | 586 // |
587 // The C2I flavor takes a stock compiled call setup plus the target method in | |
588 // Rmethod, marshals the arguments for an interpreted call and jumps to | |
589 // Rmethod->_i2i_entry. On entry, the interpreted frame has not yet been | |
590 // setup. Compiled frames are fixed-size and the args are likely not in the | |
591 // right place. Hence all the args will likely be copied into the | |
592 // interpreter's frame, forcing that frame to grow. The compiled frame's | |
593 // outgoing stack args will be dead after the copy. | |
594 // | |
595 // Native wrappers, like adapters, marshal arguments. Unlike adapters they | |
596 // also perform an offical frame push & pop. They have a call to the native | |
597 // routine in their middles and end in a return (instead of ending in a jump). | |
598 // The native wrappers are stored in real nmethods instead of the BufferBlobs | |
599 // used by the adapters. The code generation happens here because it's very | |
600 // similar to what the adapters have to do. | |
