a11bb404a5 Further refinement to kind system lattice and type-kind rules; first successful caught kind error (prohibits copying a pinned resource, though trans already caught it later). 2011-07-27 21:23:54 -07:00

d1298f768c Have bind support non-alias parametric non-bound arguments.
This was previously disallowed by the typechecker and not properly handled
in trans. I removed the typechecker check (replacing it with a simpler
check that spawned functions don't have type params) and fixed trans.
Closes #756.

4de0b3d947 Allow already bound functions to be bound again.
This commit just disables the check. All of the real work was in previous
commits that moved the target function into the bindings part of the closure
that is tracked by the tydesc.
Closes #754.

b9b674abe7 Start adding support for multiple variable declarations per stmt
This adds parser support and most of the machinery for

    auto x = 10, y = 20;

However, the above still goes wrong somewhere in typestate, causing
the state checker to believe only the last variable in the list is
initialized after the statement.

Tim, if you have a moment, could you go over the changes to the tstate
code in this patch and see where I'm going wrong?

3b2d23b2cd Move a bunch of trans into trans_common, including the context structures.
Probably more should be moved or split off into other files. My algorithm
was something along the lines of: move the contexts and their transitive
dependencies along with some functions to work with them. I stopped when
I was going to have to start pulling glue generation, which really
should go into a trans_glue file.

3ae4dcd41e Lots of work on memory tracking and channels.
We're trying to get closer to doing correct move semantics for channel
operations. This involves a lot of cleanup (such as removing the
unused sched parameter from rust_vec constructor) and making
circular_buffer kernel_owned.

Added tagging for memory allocations. This means we give a string tag
to everything we allocate. If we leak something and TRACK_ALLOCATIONS
is enabled, then it's much easier now to tell exactly what is leaking.

bd4aeef78b Beginnings of support for constrained types
Programs with constrained types now parse and typecheck, but
typestate doesn't check them specially, so the one relevant test
case so far is XFAILed.

Also rewrote all of the constraint-related data structures in the
process (again), for some reason. I got rid of a superfluous
data structure in the context that was mapping front-end constraints
to resolved constraints, instead handling constraints in the same
way in which everything else gets resolved.

This reverts commit 8c94d8fd54.

is allow main -> int to compile. Per #688, the program returns non-zero on
failure, so it's not obvious that this change is appropriate at this time.

12d5532166 Use switches rather than chained conditionals to compile alt matches
This also moves the alt-related trans code into its own file.

Closes #467

f7a1006a07 Make resolve check for type-variable name-shadowing
Capturing a type argument in the enclosing scope should be an error --
this commit implements that check in resolve, avoiding a potential
assertion failure in trans.

Closes #648.

e1620def9f In typeck, check for dynamically sized by-value arguments to thunks
A check in trans didn't have a corresponding check in typeck, causing
some programs (to wit, compile-fail/chan-parameterized-args.rs - part of this
commit) to fail with an assertion failure in trans instead of a type error.
Fixed it. In short, arguments that are future thunk arguments (any spawn
arguments, and _ arguments in bind) need to either not contain type params
or type vars, or be by-reference.

Closes #665.
