DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.
Today will be a busy real life day.
The main thing when I reach it will be exception handlers, need to preserve that state.
Another main thing will be garbage collection, a thread safe and fast way to indicate that objects are no longer being used.
Well, exception states are always known. However for some virtual machine thrown exceptions like say NullPointerException or other errors like out of memory, such states will not be known. I believe for normal exceptions the state of execution is known while for random VM errors it is not guaranteed that values will have certain values since it could happen anywhere. I would have to look that up. Perhaps for object garbage collection I can have a method cleanup which cleans up any assigned register sets at the end of a method call although that could be an issue on long loops. I could collect on object set when it is done in a register.
