681c063ec0 Conservatively serialize nearly all upcalls. Successfuly ran make check with RUST_THREADS=8, so we're probably fairly safe now. In the future we can relax the synchronization to get better performance. 2011-06-27 09:58:39 -07:00

6367bcf427 Fixed a few concurrency bugs. Still not perfect, but overall it seems much more reliable. 2011-06-27 09:58:39 -07:00

less used or unexpected combinations, as well as a selection of compile-fail

tired to manage anything that requires thinking.

f6753be655 Allow moving out of temporary values 
This will probably need more work, as moving doesn't appear to do
quite the right thing yet in general, and we should also check
somewhere that we're not, for example, moving out the content out of
an immutable field (probably moving out of fields is not okay in
general).

61fc12d0d0 Partial implementation of resources 
Non-copyability is not enforced yet, and something is still flaky with
dropping of the internal value, so don't actually use them yet. I'm
merging this in so that I don't have to keep merging against new
patches.

582e1f13f0 Invalidate constraints correctly after an assignment expression 
Modified typestate to throw away any constraints mentioning a
variable on the LHS of an assignment, recv, assign_op, or on
either side of a swap.

Some code cleanup as well.

2ebd19477b Sanitize use of ids for obj constructors. 
Typeck and trans used to, by historical coincidence, use the item_obj
node id, which was used to identify the obj type by the rest of the
system, for the constructor function. This is now identified by the
ctor id stored in the tag throughout.

The implementation is so simple it might be considered cheating: at almost
every step the expr_ternary is just converted to expr_if.

We decided to use metadata for the more complex cases, and a simple
string is enough for rustc right now.

3cf00c1577 Correct error message for argument mode mismatch 
If you use a function expecting an alias argument in a context that
expects a function expecting a value argument, or vice versa, the
previous error message complained that the number of arguments was
wrong. Fixed the error message to be accurate.

9a48bd2f21 Compute typestate properly for move 
typestate now drops constraints correctly in the post-state of
a move expression or a declaration whose op is a move. It doesn't
yet drop constraints mentioning variables that get updated.

To do this, I had to change typestate to use trit-vectors instead
of bit-vectors, because for every constraint, there are three
possible values: known-to-be-false (e.g. after x <- y, init(y) is
known-to-be-false), known-to-be-true, and unknown. Before, we
conflated known-to-be-false with unknown. But move requires them
to be treated differently. Consider:

(program a)
(a1) x = 1;
(a2) y <- x;
(a3) log x;

(program b)
(b1) x = 1;
(b2) y <- z;
(b3) log x;

With only two values, the postcondition of statement a2 for
constraint init(x) is the same as that of b2: 0. But in (a2)'s
postcondition, init(x) *must* be false, but in (b2)'s condition,
it's just whatever it was in the postcondition of the preceding statement.
