The things that usually go wrong:
- wp fall through: add +, e.g.
apply (wp select_wp) -> apply (wp select_wp)+
- precondition: you can remove most hoare_pre, but wpc still needs it, and
sometimes the wp instance relies on being able to fit a rule to the
current non-schematic precondition. In that case, use "including no_pre"
to switch off the automatic hoare_pre application.
- very rarely there is a schematic postcondition that interferes with the
new trivial cleanup rules, because the rest of the script assumes some
specific state afterwards (shouldn't happen in a reasonable proof, but
not all proofs are reasonable..). In that case, (wp_once ...)+ should
emulate the old behaviour precisely.
This commit should at least remove merge conflict markers, and the idea
is that at least refine, crefine, drefine, and infoflow (with sorrys)
build. Subsequent commits may be required to fix build issues that I
have not picked up.
* The definitions of the separation "arrows" is slightly nicer and more consistent.
- We have a nicer correspondence between sep_map_c and sep_map_s.
- sep_map_irq now specifies exactly what the IRQ table contains
(that it *only* has one entry, not that it contains at least that entry).
- Nicer LaTeX output for the arrows.
* A number of minor renaming of constants and types.
- cdl_component => cdl_component_id
- sep_entity => cdl_component
- state_sep_projection => sep_state_projection
- obj_to_sep_state => object_to_sep_state
* Removed a few unused lemmas.
