7426252549 Generate code properly for calls with _|_ - typed arguments 
The code for translating a fail (for example) would call
Unreachable(), which terminates the block; if a fail appeared as an
argument, this would cause an LLVM assertion failure. Changed
trans_call to handle this situation correctly.

4e59b0be54 Sync rust_chan's deref() method with rustc's code. 
If the channel is associated with a port then the destructor will assert.
Additionally, destruction of the object is not always appropriate. This brings
the deref() method into sync with the behavior of generated rust code which
only invokes destroy() once the reference count goes to 0.

02a5949aba Add macro for refcounting runtime structures. 
The macro with the extra dtor parameter is intended for structures like
rust_chan which may not necessarily delete themselves when the ref count
becomes 0. This functionality will be used in an upcoming changeset.

73cc624e8e Move the channel destroy code into rust_chan. 
This lets native code more easily destroy channels since directly deleting a
channel is not always the right way to destroy it.

09921cf86f Move channel cloning logic into a method on rust_chan.

Marijn Haverbeke
432e5e9f7f Allow dereferencing of single-variant, single-argument tag values 
(Using the * operator.)

This makes tags more useful as nominal 'newtype' types, since you no
longer have to copy out their contents (or construct a cumbersome
boilerplate alt) to access them.

I could have gone with a scheme where you could dereference individual
arguments of an n-ary variant with ._0, ._1, etc, but opted not to,
since we plan to move to a system where all variants are unary (or, I
guess, nullary).

57e6340253 Allow 'newtype' syntax for tags

fb72be0a89 Do not store a tag num for single-variant tags 
This is a preparation for tags-as-nominal-types. A tag that has only a
single variant is now represented, at run-time, as simply a tuple of
the variant's parameters, with the variant id left off.

7b1b5d5a8a Implement autoderef for function calls. 
This is important since we are going to be making functions noncopyable
soon, which means we'll be seeing a lot of boxed functions.
(*f)(...) is really just too heavyweight.

Doing the autodereferencing was a very little bit tricky since
trans_call works with an *lval* of the function whereas existing
autoderef code was not for lvals.

4519f54857 Warn for unused variables 
Modify typestate to check for unused variables and emit warnings
where relevant. This exposed a (previously harmless) bug in
collect_locals where outer functions had bit-vector entries
for init constraints for variables declared in their inner
nested functions. Fixing that required changing collect_locals to
use visit instead of walk -- probably a good thing anyway.

4165d3640a Add a pass to fold out items that do not belong in the current configuration 
The parser needs to parse unconfigured items into the AST so that they can
make the round trip back through the pretty printer, but subsequent passes
shouldn't care about items not being translated. Running a fold pass after
parsing is the lowest-impact way to make this work. The performance seems
fine.

31ec26d46a Make calling resource destructors work cross-crate 
Tydescs are currently re-created for each compilation unit (and I
guess for structural types, they have to be, though the duplication
still bothers me). This means a destructor can not be inlined in the
drop glue for a resource type, since other crates don't have access to
the destructor body.

Destructors are now compiled as separate functions with an external
symbol that can be looked up in the crate (under the resource type's
def_id), and called from the drop glue.

190644063e Be more strategic about linking to rust crates 
Instead of linking directly to the rust crate, try to figure out the location
and name of the library from the file name, then call gcc with appropriate -L,
-l flags. This will allow dynamic linking to be more forgiving about where it
loads the library from at runtime - currently a stage3 compiler can't run
correctly from the stage0 directory. Only tested on Linux. Fingers crossed.

1c852ac9c0 Removing runtime tests. The runtime is tested well enough by the standard library tests, so we might as well have less code to fix during refactoring. 2011-06-28 16:12:33 -07:00

a83b64d15d Rework how linkage attributes are determined 
The meta items within a crate's link attribute are used in linkage:

 #[link(name = "std",
        vers = "1.0",
        custom = "whatever")];

Name and vers are treated specially, and everything else is hashed together
into the crate meta hash.

9561def209 Use 'resource' rather than 'res' as a keyword 
Resources are now defined like...

    resource fd(int n) { close(n); }

Calling fd with an int will then produce a non-copyable value
that, when dropped, will call close on the given int.
