source: src/LIN/joint_LTL_LIN_semantics.ma @ 1384

Last change on this file since 1384 was 1384, checked in by sacerdot, 8 years ago
  • fetch_ra taken out of pop_frame again since it is used uniformly and it is also required for is_final
  • fetch_ra made abstract since it gets a different implementation in RTL
  • old fetch_ra renamed into load_ra (to match the save_ra name)
