// Declares a Simulator for MIPS instructions if we are not generating a native

// MIPS binary. This Simulator allows us to run and debug MIPS code generation

// on regular desktop machines.
|

// Dart calls into generated code by "calling" the InvokeDartCode stub,
|
|
// which will start execution in the Simulator or forwards to the real entry
|
|
// on a MIPS HW platform.
