88f29aab27 Use attributes for native module ABI and link name 
This patch changes how to specify ABI and link name of a native module.

Before:
  native "cdecl" mod llvm = "rustllvm" {...}

After:
  #[abi = "cdecl"]
  #[link_name = "rustllvm"]
  native mod llvm {...}

The old optional syntax for ABI and link name is no longer supported.

Fixes issue #547

fba0df72d3 Use attributes for native module ABI and link name [temp] 
This patch adds support of using attributes to specify native mode ABI
and link name. The old optional syntax like:
  native "cdecl" mod llvm = "rustllvm" { ... }
is still supported.

This is a transitional commit to avoid making a stage1 (backward
imcompatible) snapshot.

9ff6f816ba Fix handling of loops and conditionals in alias.rs 
It now threads information about invalidated aliases through the AST
properly. This makes it more permissive for conditionals (invalidating
an alias in one branch doesn't prevent you from using it in another),
and less permissive for loops (it now properly notices when a loop
invalidates an alias that it might still use in another iteration).

253242390c Use ".ll" as default suffix of LLVM assembly file 
This commit is a follow up of Issue #1147.

Althought there are some inconsistency about this naming convention in
LLVM. For example, `clang' write LLVM assembly to a file with ".s" suffix,
while both `llvm-dis' and `opt' write to files with ".ll" suffices. We
think ".ll" makes more sense.

Also rustc manual page is updated.

61b604580b Fix alignment of interior pointers of dynamic-size types. Closes #1112 
GEP_tup_like finds interior pointers by creating a tuple of all the types
preceding the element it wants a pointer to, then asks for the size of that
tuple. This results in incorrect pointers when the alignment of that tuple
is not the alignment of the interior type you're getting a pointer to.

7dacccde94 Make shared kind the default only for generic functions 
You almost never want a function with pinned type params. For
types, objects, resources, and tags, pinned types are actually often
more sane. For most of these, shared rarely makes sense. Only tricky
case is objs -- you'll have to think about the kinds you want there.

b0a72ee06a Be more careful when parsing block calls 
Previously, the parser would try to interpret this as a block call:

    if true {} // No semicolon
    {|i, am, a, block|};

Which, though unlikely, might come up in practice.

7114702496 Change the way block calls are parsed, mark them as block-calls. 
This makes it possible to omit the semicolon after the block, and will
cause the pretty-printer to properly print such calls (if
pretty-printing of blocks wasn't so broken). Block calls (with the
block outside of the parentheses) can now only occur at statement
level, and their value can not be used. When calling a block-style
function that returns a useful value, the block must be put insde the
parentheses.

0714bb5f7d Fix the problem with check-fast randomly failing 
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.

No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.

ad5014bf4c Fix link error by explicitly link needed DSOs 
Building Rust(version 280bc56) on Ubuntu 11.10 failed with link error,
like:

compile_and_link: stage0/lib/rustc/i686-unknown-linux-gnu/lib/libstd.so
compile_and_link: stage0/lib/rustc/i686-unknown-linux-gnu/bin/rustc
/local/src/rust/build/stage0/lib/rustc/i686-unknown-linux-gnu/lib/librustrt.so:
undefined reference to `clock_gettime'
collect2: ld returned 1 exit status
error: linking with gcc failed with code 1

GCC toolchain released by Ubuntu 11.10 introduced a few compiler flags
that are different with upstream GCC[1]. Flags "-Wl,--as-needed' and
'-Wl,--no-copy-dt-needed-entries' are passed by default.

Function clock_gettime from librt is used by librustrt, indirectly by
rustc. It is necessary to explicitly pass the "-lrt" flags when building
rustc.

Please note since the toolchain changes will be the default in the next
release(2.22) of binutils, this is not actually a Debian/Ubuntu specific
issue.

6e652588bf Get rid of 'overwrite' destination kind 
It wasn't safe (computing the rval might invalidate the lval addr), and needlessly
complicating things (code was already building up intermediary results to work
around other unsafeties).

the ideal fix.

So *resource, ~resource, [resource] are all pinned. This is counter to the

Once we've established a good baseline with lots of tests, then we can try to
make raising pinned kinds work.

420484579d Better handling of unreachable code in trans 
The builder functions in trans_build now look at an 'unreachable' flag
in the block context and don't generate code (returning undefined
placeholder values) when this flag is set. Threading the unreachable
flag through context still requires some care, but this seems a more
sane approach than re-checking for terminated blocks throughout the
compiler.

When creating a block, if you use its closest dominator as parent, the
flag will be automatically passed through. If you can't do that,
because the dominator is a scope block that you're trying to get out
of, you'll have to do something like this to explicitly pass on the
flag:

    if bcx.unreachable { Unreachable(next_cx); }

575aae407b Saner approach to lvalues and callable values in trans 
LValues no longer carry information about generics and objs, instead
there's an extended form of lvalue, lval_maybe_callee, only used by
call and bind, which holds this info.

This makes it possible to take the value of a method and get a working
closure, and will (with some more work) allow us to call statically
known functions without loading from their pair.

- Loop bodies and resource constructors aren't allowed to have
  trailing expressions anymore.

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).
