#include "Core/MIPS/MIPS.h"

// Fast switch-tree interpreter dispatcher, generated into InterpreterDispatch.cpp by
// GenerateInterpreterDispatch() in MIPSTables.cpp. Executes op on mips (same convention as
// the MIPSInt::Int_* handlers it calls into) and returns the number of cycles it consumed -
// or -1 if op isn't a recognized instruction (an invalid encoding, or one of the handful of
// real instructions with no interpreter implementation, e.g. tge/tlt/teq/...). Not total by
// design: the caller must fall back to MIPSInterpret() on a negative return, since deciding
// what "unhandled" means is a caller policy, not something a mechanically generated dispatch
// tree should embed.
