In this commit, we add a function `userAnnotatedSources` which replaces `isStandardSource`. It generates a list of all the user annotated ScopedFunctions. This list is used to filter modules for solving. This requires a slight refactor within `FunctionAnalysis.hs`. * Add `extern_remove_dirty` test. The basic idea is this: 1. Find all wrapper functions. 2. Compute their respective set of reachable functions. 3. Mark them all as 'don't check' unless they are referenced from a different source as well.
Don't verify `@external`-generated wrapper functions
* Use `ssh-agent` to clone with specific private key * Set `0o400` permissions on private key file * Add `mathsat` to list of solvers used in tests
Add mathsat installation to Github actions workflow

There was a problem hiding this comment.
Does this agree with the docstring?
// Verifies that 0 <= a <= b.
//
// Prover assumption: b < RANGE_CHECK_BOUND.
//
// This function is still sound without the prover assumptions. In that case, it is guaranteed
// that a < RANGE_CHECK_BOUND and b < 2 * RANGE_CHECK_BOUND.
// @pre b < 2**128
// @post 0 <= a and a <= b
func assert_nn_le{range_check_ptr}(a, b) {
assert_nn(a);
assert_le(a, b);
return ();
}Looks like the b < rcBound is an assumption. But I suppose we want that in the post so other stuff can use it?
