Class OpcodeImpl

java.lang.Object
com.dylibso.chicory.runtime.OpcodeImpl
public final class OpcodeImpl extends Object
Note: Some opcodes are easy or trivial to implement as compiler intrinsics (local.get, i32.add, etc). Others would be very difficult to implement and maintain (floating point truncations, for example). The idea of this class is to share the core logic of both the interpreter and AOT implementations for shareable opcodes (that is, opcodes that are not completely different in operation depending on whether they're run in the interpreter or in the AOT, such as local.get, local.set, etc) in a single place that is statically accessible. If the AOT does not have an intrinsic for an opcode (and the opcode is not a flow control opcode), then a static call will be generated to the method in this class that implements the opcode.

Note about parameter ordering: because of the JVM's calling convention, the parameters to a method are ordered such that the last value pushed is the last argument to the method, i.e., method(tos - 2, tos - 1, tos).
