It was required to get iOS compilable but since
that time a couple of changes were introduced
which cause the same bug to re-appear and broke 
build anyway. Fixing all of them doesn’t look a 
viable alternative to me as it will pollute the 
code too much.

So it should be fixed from LLVM side and I hope 
LLVM will upstream corresponding changes in a 
month.

Meanwhile, who wants to play with Rust on iOS is 
better to use a fork which uses patched LLVM:
https://github.com/vhbit/rust/tree/ios . It may 
lag behind master a bit, but it is Travis-checked 
to compile successfully.

9766b493fc auto merge of : omasanori/rust/asctime, r=alexcrichton
In C, `ctime(t)` is equivalent to `asctime(localtime(t))`, so the result should depend on the local timezone. Current `ctime` is compatible with `asctime` in C, not `ctime`.

This commit renames `ctime` to `asctime` and adds `ctime` which converts the time to the local timezone before formatting it.

This commit also fixes the documentation of them. Current documentation of `ctime` says it returns "a string of the current time." However, it actually returns a string of the time represented as `self`, not the time when it is called.

parameters.

This can break code that mistakenly used type parameters in place of
`Self`. For example, this will break:

    trait Foo {
        fn bar<X>(u: X) -> Self {
            u
        }
    }

Change this code to not contain a type error. For example:

    trait Foo {
        fn bar<X>(_: X) -> Self {
            self
        }
    }

e38cb972dc Simplify PatIdent to contain an Ident rather than a Path
Rationale: for what appear to be historical reasons only, the PatIdent contains
a Path rather than an Ident.  This means that there are many places in the code
where an ident is artificially promoted to a path, and---much more problematically---
a bunch of elements from a path are simply thrown away, which seems like an invitation
to some really nasty bugs.

This commit replaces the Path in a PatIdent with a SpannedIdent, which just contains an ident
and a span.

8877b81f2c Add os::join_paths, make setenv non-utf8 capable
This commit changes `os` in three ways:

* It adds a `join_paths` function that is the converse to `split_paths`,
  easing manipulation of the `PATH` environment variable according to
  platform conventions.

* **Breaking change**: It changes `split_paths` to no longer drop empty paths, since they are
  meaningful to some shells (where they are synonymous with the current
  working directory).

* It changes `setenv` to take a `BytesContainer` rather than a `&str`
  value, since environment variables may have non-utf8 values on some
  platforms. Since `&str` is a `BytesContainer`, this is *not* a
  breaking change.

Along the way, it also refactors the `split_paths` function so that
`cfg` switches are applied internally (and the function header is given
only once). This fixes a bug: the doc comment had an example for only
one platform.

One of the examples in the docs on adding documentation to rust code has an error that will cause the function to run endlessly rather than return the desired result, should someone actually implement this for some reason. While the error does not hinder the explanation of documenting code, it does look better if it is corrected.

So far, type names generated for debuginfo where a bit sketchy. It was not clearly defined when a name should be fully qualified and when not, if region parameters should be shown or not, and other things like that.
This commit makes the debuginfo module responsible for creating type names instead of using `ppaux::ty_to_str()` and brings type names (as they show up in the DWARF information) in line with GCC and Clang:

* The name of the type being described is unqualified. It's path is defined by its position in the namespace hierarchy.
* Type arguments are always fully qualified, no matter if they would actually be in scope at the type definition location.

Care is also taken to make type names consistent across crate boundaries. That is, the code now tries make the type name the same, regardless if the type is in the local crate or reconstructed from metadata. Otherwise LLVM will complain about violating the one-definition-rule when using link-time-optimization.

This commit also removes all source location information from type descriptions because these cannot be reconstructed for types instantiated from metadata. Again, with LTO enabled, this can lead to two versions of the debuginfo type description, one with and one without source location information, which then triggers the LLVM ODR assertion.
Fortunately, source location information about types is rarely used, so this has little impact. Once source location information is preserved in metadata () it can also be re-enabled for type descriptions.

`RUSTFLAGS=-g make check` no works again for me locally, including the LTO test cases (note that I've taken care of  by reverting the change in LLVM that @luqmana identified as the culprit for that issue).

I believe there's more commonality to be found there but maybe small steps are better. I'm also in the process of documenting what I can, I will see if I can add it to this PR.

It also seems to me that ideally some of this stuff (especially the pattern sanity check) could live as a separate compiler-agnostic module but I understand this may not be the right time (if not the worst) to start the process of modularising rustc.

The current implementation of `rotate_left` and `rotate_right` are incorrect when the rotation amount is 0, or a multiple of the input's bitsize. When `n = 0`, the expression

    (self >> n) | (self << ($BITS - n))

results in a shift left by `$BITS` bits, which is undefined behavior (see https://github.com/rust-lang/rust/issues/10183), and currently results in a hardcoded `-1` value, instead of the original input value. Reducing `($BITS - n)` modulo `$BITS`, simplified to `(-n % $BITS)`, fixes this problem.

One possible issue is that `install.sh` doesn't have a `need_cmd` definition like `configure` does. Should this be ported over as well?

Platform-detection code from `configure` copied over to `install.sh` in
order to special case the lib dir being `bin` on Windows instead of
