sim: example-synacor: a simple implementation for reference Provide a simple example simulator for people porting to new targets to use as a reference. This one has the advantage of being used by people and having a fun program available for it. It doesn't require a special target -- the example simulators can be built for any existing port. 2020-12-10 11:26:30 +08:00			`# check the RMEM & WMEM insns.`
