From 76d6098afee476b45070809b2ea9c8764b1e9adf Mon Sep 17 00:00:00 2001 From: Ryan Scott Date: Tue, 6 Dec 2022 16:46:10 -0500 Subject: [PATCH 1/5] saw-core-coq: Remove silly redefinitions of true/false We were previously defining the following in the Coq support library: ```coq Definition true := Datatypes.true. Definition false := Datatypes.false. ``` This is rather silly, as we could just as well use `Datatypes.true` and `Datatypes.false` directly. What's more, redefining `true` causes issues in a subsequent commit that adds `lia` support for `bitvector`s, so it is especially important to remove `true` for that reason. This removes the redefined versions of `true` and `false`, and it also tweaks `SpecialTreatment.hs` to translate SAWCore's `True`/`False` into `Datatypes.true`/`Datatypes.false`. Although this is technically a breaking change, it is a change that is very unlikely to break existing proofs (unless your proofs directly mention `SAWCoreScaffolding.true` or `SAWCoreScaffolding.false`).

It would be nice to rip out these wrapper functions, but unfortunately, doing so would induce a fair bit of breakage in downstream code. For now, we simply record the fact that these functions are deprecated, and we will revisit whether we want to remove them at a later date. --- .../CryptolToCoq/SAWCoreScaffolding.v | 26 +++++++++++++++++++ 1 file changed, 26 insertions(+) diff --git a/saw-core-coq/coq/handwritten/CryptolToCoq/SAWCoreScaffolding.v b/saw-core-coq/coq/handwritten/CryptolToCoq/SAWCoreScaffolding.v index b48a82de4e..1421fe4474 100644 --- a/saw-core-coq/coq/handwritten/CryptolToCoq/SAWCoreScaffolding.v +++ b/saw-core-coq/coq/handwritten/CryptolToCoq/SAWCoreScaffolding.v @@ -42,6 +42,7 @@ Instance Inhabited_Intro (a:Type) (b:a -> Type) (Hb: forall x, Inhabited (b x)) Global Hint Extern 5 (Inhabited ?A) => (apply (@MkInhabited A); intuition (eauto with typeclass_instances inh)) : typeclass_instances. +(** DEPRECATED: Use [string] instead. *) Definition String := String.string.
