// Implementation of AdapterHandlerLibrary |
|
458 |
// |
|
459 |
// This library manages argument marshaling adapters and native wrappers. |
|
460 |
// There are 2 flavors of adapters: I2C and C2I. |
|
461 |
// |
|
462 |
// The I2C flavor takes a stock interpreted call setup, marshals the arguments |
|
463 |
// for a Java-compiled call, and jumps to Rmethod-> code()-> |
|
464 |
// instructions_begin(). It is broken to call it without an nmethod assigned. |
|
465 |
// The usual behavior is to lift any register arguments up out of the stack |
|
466 |
// and possibly re-pack the extra arguments to be contigious. I2C adapters |
|
467 |
// will save what the interpreter's stack pointer will be after arguments are |
|
468 |
// popped, then adjust the interpreter's frame size to force alignment and |
|
469 |
// possibly to repack the arguments. After re-packing, it jumps to the |
|
470 |
// compiled code start. There are no safepoints in this adapter code and a GC |
|
471 |
// cannot happen while marshaling is in progress. |
|
472 |
// |
|
473 |
// The C2I flavor takes a stock compiled call setup plus the target method in |
|
474 |
// Rmethod, marshals the arguments for an interpreted call and jumps to |
|
475 |
// Rmethod->_i2i_entry. On entry, the interpreted frame has not yet been |
|
476 |
// setup. Compiled frames are fixed-size and the args are likely not in the |
|
477 |
// right place. Hence all the args will likely be copied into the |
|
478 |
// interpreter's frame, forcing that frame to grow. The compiled frame's |
|
479 |
// outgoing stack args will be dead after the copy. |
|
480 |
// |
|
481 |
// Native wrappers, like adapters, marshal arguments. Unlike adapters they |
|
482 |
// also perform an offical frame push & pop. They have a call to the native |
|
483 |
// routine in their middles and end in a return (instead of ending in a jump). |
|
484 |
// The native wrappers are stored in real nmethods instead of the BufferBlobs |
|
485 |
// used by the adapters. The code generation happens here because it's very |
|
486 |
// similar to what the adapters have to do. |
