This replaces `*` with `..` in enums, `_` with `..` in structs, and `.._` with `..` in vectors. It adds obsolete syntax warnings for the old forms but doesn't turn them on yet because we need a snapshot.
#5830
This PR improves the single-stepping experience for if-expression (no more jumping into the *else* branch before entering the *then* branch, no more jumping to the end of the *else* branch after finishing the *then* branch). Unfortunately I don't know of a straight-forward way of writing automated tests for this. Suggestions welcome!
Changes:
* default value when no args
* license
* removed libc printing
* use extra::bigint instead of handmade gmp binding
The drawback is that it's 2 order of magnitude slower, the good news is that there is a good bench for extra::bigint.
If a function is marked as external, then it's likely desired for use with some
native library, so we're not really accomplishing a whole lot by internalizing
all of these symbols.

This commit fixes issue #10468.
It propagate optimization level from PkgSrc to compile_crate as a rustc::driver::session::OptLevel enum.
The 'opt' argument to compile_crate was previously hardcoded as boolean false, such that calls to session::options would always result in the session::No flag being used.
* moved `extern` inside module
* changed `extern "stdcall"` to `extern "system"`
* changed `cfg(target_os="win32")` to `cfg(windows)`
* only run on Windows && x86, (not x86_64)
* updated copyright dates
There was a syntax error because the `extern "stdcall"` was outside the module instead of inside it.

* change `extern "stdcall"` to `extern "system"`
* change `cfg(target_os="win32")` to `cfg(windows)`
* updated copyright dates
* changed log(error, ...) => info!(....)
* added `pub` keyword to kernel32 functions
Changes:
* add licence;
* remove usage of libc and unsafe;
* use BufferedWriter to improve performance;
* use a DummyWriter to cancel binary output in test.
If any of the digits was one past the maximum (e.g. 10**9 for base 10),
then this wasn't detected correctly and so the length of the digit was
one more than expected, causing a very large allocation.
Fixes#10522.
Fixes#10288.

These commits create a `Buffer` trait in the `io` module which represents an I/O reader which is internally buffered. This abstraction is used to reasonably implement `read_line` and `read_until` along with at least an ok implementation of `read_char` (although I certainly haven't benchmarked `read_char`).

This implementation of the meteor contest implements:
- insertion check with bit trick;
- pregenetation of every feasible placement of the pieces on the
board;
- filtering of placement that implies unfeasible board
- central symetry breaking
related to #2776
I've started working on this issue and pushed a small commit, which adds a range check for integer literals in `middle::const_eval` (no `uint` at the moment)
At the moment, this patch is just a proof of concept, I'm not sure if there is a better function for the checks in `middle::const_eval`. This patch does not check for overflows after constant folding, eg:
let x: i8 = 99 + 99;
Bare functions are another example of a scalar but non-numeric
type (like char) that should be handled separately in casts.
This disallows expressions like `0 as extern "Rust" fn() -> int;`.
It might be advantageous to allow casts between bare functions
and raw pointers in unsafe code in the future, to pass function
pointers between Rust and C.
Closes#8728
