Since Coq 8.12, `omega` is flagged as deprecated and scheduled for removal.
Also replace CompCert's homemade tactics `omegaContradiction`, `xomega`,
and `xomegaContradiction` with `lia` and `extlia`.
Turn back on the deprecation warning for uses of `omega`.
Make the proof of `Ctypes.sizeof_pos` more robust to variations in `lia`.
|
|
|
|
|
| |
Instead, use definitions and lemmas from the Coq standard library
(ZArith, Znumtheory).
|
|
|
|
|
|
|
| |
Use Z.to_nat theorems from the standard Coq library in preference to
our theorems in lib/Coqlib.v.
Simplify lib/Coqlib.v accordingly.
|
|
|
|
|
|
|
|
|
| |
This is required for compatibility with
https://github.com/coq/coq/pull/8064, where prim token notations no longer
follow `Require`, but instead follow `Import`.
Closes #246
Closes #250

Replace deprecated functions and theorems from the Coq standard library (version 8.6) by their non-deprecated counterparts.

- Coqlib: option_rel to lift a relation to option type.
- Coqlib: more lemmas about list_forall2.
- Coqlib: introduce type nlist (nonempty lists) and some operations.
- Maps: a variant of PTree.elements_extensional that uses option_rel.

- Define type "block" as "positive" instead of "Z".
- Strengthen mem_unchanged_on so that the permissions are identical,
instead of possibly increasing.
- Move mem_unchanged_on from Events to Memory.Mem.
- Define it in terms of mem_contents rather than in terms of Mem.load.
- ExportClight: try to name temporaries introduced by SimplExpr
- SimplExpr: avoid reusing temporaries between different functions,
instead, thread a single generator through all functions.

- In Cminor and below, removed pointer validity check in semantics of
comparisons, so that evaluation of expressions is independent of
memory state.
- In Cminor and below, removed "alloc" instruction.
- Cleaned up commented-away parts.
