This patch was created using find name *.v  xargs L 1 awk i inplace '{from = 0} /^From/{ from = 1; ever_from = 1} { if (from == 0 && seen == 0 && ever_from == 1) { print "Set Default Proof Using \"Type*\"."; seen = 1 } }1 ' and some minor manual editing

This class whose name is horrible and purpose is arbitrary seems to be a leftover of some experiment with ch2o, a long time a ago.

Major changes: * A data structure to collect locked addresses in memory. * Operations to lock and unlock addresses. * Remove [ctree_Forall] and express it using [Forall] and [ctree_flatten]. This saves a lot of lines of code. * Add a [void] value. This value cannot be typed, but will be used as a dummy return value for functions with return type [void]. Minor changes: * Various deciders in preparation of the executable semantics. * Improve naming and notations. * Remove obsolete stuff.

The refactoring includes: * Use infix notations for the various list relations * More consistent naming * Put lemmas on one line whenever possible * Change proofs into oneliners when possible * Make better use of the "Implicit Types" command * Improve the order of the list module by placing all definitions at the start, then the proofs, and finally the tactics. Besides, there is some new machinery for proofs by reflection on lists. It is used for a decision procedure for permutations and list containment.

Both the operational and axiomatic semantics are extended with sequence points and a permission system based on fractional permissions. In order to achieve this, the memory model has been completely revised, and is now built on top of an abstract interface for permissions. Apart from these changed, the library on lists and sets has been heavily extended, and minor changed have been made to other parts of the prelude.

The development now corresponds exactly to the FoSSaCS 2013 paper. Also, the prelude is updated to the one of the master branch.

* Define the standard strict order on pre orders. * Prove that this strict order is well founded for finite sets and finite maps. We also provide some utilities to compute with well founded recursion. * Improve the "simplify_option_equality" tactic to handle more cases. * Axiomatize finiteness of finite maps by translation to lists, instead of by them having a finite domain. * Prove many additional properties of finite maps. * Add many functions and theorems on lists, including: permutations, resize, filter, ...
