86c1f16a10 Fix bad interaction between last-use finding and references 
The last-use pass now takes input from the alias pass to not mark things
as last uses that are still accessed through a reference.

f6491bb426 Update stdlib, compiler, and tests to new kind system 
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.

cefff237bf Make tag, resource and object constructors take their arguments by copy 
Doing something like some([1, 2, 3]) will now no longer create a temporary
copy of the vector. It will also be easier for the kind checker to see that
putting a resource into a data-structure constructor is safe.

4e03112141 Add a pass-by-copy parameter passing convention 
This is intended to solve the problem of how to pass arguments to
constructor functions -- you want to move in rvalues, but not have to
explicitly copy stuff that is not an rvalue. The by-copy passing
convention will ensure the callee gets its own copy of the value. For
rvalues, it'll just pass off the value. For lvalues, it'll make a
copy.

9cf48d3753 Preparation for kind system overhaul

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.

fba0df72d3 Use attributes for native module ABI and link name [temp] 
This patch adds support of using attributes to specify native mode ABI

is still supported.

This is a transitional commit to avoid making a stage1 (backward

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

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.

You almost never want a function with pinned type params. For

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.
 2011-10-21 14:55:54 +02:00
Marijn Haverbeke
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.

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.
