r? anyone.
You can see a bit more discussion on #7655.
This does not close any ticket; I am just scratching an itch. Note in particular that I picked the value `{:>9} ns/iter` pretty much out of a hat. :)
(scratching an itch.)
Rebased and updated.
Fixed bug: omitted field init from embedded struct literal in a test.
Fixed bug: int underflow during padding length calculation.
In addition, the renderer will add comments to structs and enums saying
that fields or variants have been stripped.
The comments are currently
```rust
// some fields stripped
// some variants stripped
```
I was thinking of changing that to "some private..." but passes other than
strip-private may strip fields or variants as well.

This adds `get_opt` to `std::vec`, which looks up an item by index and returns an `Option`. If the given index is out of range, `None` will be returned, otherwise a `Some`-wrapped item will be returned.
Example use case:
```rust
use std::os;
fn say_hello(name: &str) {
println(fmt!("Hello, %s", name));
}
fn main(){
// Try to get the first cmd line arg, but default to "World"
let args = os::args();
let default = ~"World";
say_hello(*args.get_opt(1).unwrap_or(&default));
}
```
If there's an existing way of implementing this pattern that's cleaner, I'll happily close this. I'm also open to naming suggestions (`index_opt`?)
Example:
void ({ i64, %tydesc*, i8*, i8*, i8 }*, i64*, %"struct.std::fmt::Formatter[#1]"*)*
Before, we would print 20 levels deep due to recursion in the type
definition.
r? @metajack When I started writing the rustpkg tests, task failure didn't set the
exit code properly. But bblum's work from July fixed that. Hooray! I
just didn't know about it till now.
So, now rustpkg uses exit codes in a more conventional way, and some of
the tests are simpler.
The bigger issue will be to make task failure propagate the error message.
Right now, rustpkg does most of the work in separate tasks, which means if
a task fails, rustpkg can't distinguish between different types of failure
(see #3408)

This patch removes the code responsible for handling older CrateMap versions (as discussed during #9593). Only the new (safer) layout is supported now.
I've left out a way to construct from a `Send` type until #9509 is resolved. I am confident that this interface can remain backwards compatible though, assuming we name the `Pointer` trait method `borrow`.
When there is a way to convert from `Send` (`from_send`), a future RAII-based `Mut` type can be used with this to implemented a mutable reference-counted pointer. For now, I've left around the `RcMut` type but it may drastically change or be removed.
There's currently a fair amount of code which is being ignored on unnamed blocks
(which are the default now), and I opted to leave it commented out for now. I
intend on very soon revisiting on how we perform linking with extern crates in
an effort to support static linking.
I borrow some ideas from clang's ABIInfo.h and TargetInfo.cpp.
LLVMType is replaced with ArgType, which is similar to clang's ABIArgInfo,
and I also merge attrs of FnType into it.
Now ABI implementation doesn't need to insert hidden return pointer
to arg_tys of FnType. Instead it is handled in foreign.rs.
This change also fixes LLVM assertion failure when compiling MIPS target.
r? @pcwalton Sadly, there's a lack of resources for maintaining the `rust` tool,
and we decided in the 2013-10-08 Rust team meeting that it's better
to remove it altogether than to leave it in a broken state.
This deletion is without prejudice. If a person or people appear who
would like to maintain the tool, we will probably be happy to
resurrect it!
Closes#9775

r? @metajack rustpkg now makes source files that it checks out automatically read-only, and stores
them under build/.
Also, refactored the `PkgSrc` type to keep track of separate source and destination
workspaces, as well as to have a `build_workspace` method that returns the workspace
to put temporary files in (usually the source, sometimes the destination -- see
comments for more details).
Closes#6480

Some bug fixes to reexported statics in stage0 now, also some macro attribute goodies. Mostly just updating the snapshot to help enable some things that its patches have been blocking.
