// This library manages argument marshaling adapters and native wrappers.
// There are 2 flavors of adapters: I2C and C2I.
//
-// The I2C flavor takes a stock interpreted call setup, marshals the arguments
-// for a Java-compiled call, and jumps to Rmethod-> code()->
-// instructions_begin(). It is broken to call it without an nmethod assigned.
-// The usual behavior is to lift any register arguments up out of the stack
-// and possibly re-pack the extra arguments to be contigious. I2C adapters
-// will save what the interpreter's stack pointer will be after arguments are
-// popped, then adjust the interpreter's frame size to force alignment and
-// possibly to repack the arguments. After re-packing, it jumps to the
-// compiled code start. There are no safepoints in this adapter code and a GC
-// cannot happen while marshaling is in progress.
