main novelties:
- there is an in-built stack_usage nat in joint states, at the base of the new division of RTL's semantics (with separate stacks, with separate stacks but with an artificial overflow error, with a unique stack)
- a premain is added semantically to the global env, so initial cost label and main call and return are observed
- proper initialization is now in LINToASM (to be sure, endianess should be checked ;-)
The update breaks proofs of back end atm. compiler.ma should be okay, but I have not had time to complete its compilation.
