source: src/RTL/ @ 3007

Last change on this file since 3007 was 2946, checked in by tranquil, 7 years ago

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. should be okay, but I have not had time to complete its compilation.
