When MSYS shell executes program, if its arguments look like MSYS paths,
MSYS automatically converts them into Windows paths.
For example, `/c/path:/d/path` becomes `C:\path;D:\path`.
However, if there is only one path e.g. `/c/path`, it becomes `C:/path`.
maketest.py reverts the behavior to reduce confusion between MSYS and
Windows, but it didn't handle the `/c/path` case. This patch fixes the
issue.

We shouldn't be setting any settings in the syntax file. Better to put
them in the ftplugin, where they won't be pulled in by :syn-include and
can be cleaned up when changing the filetype.
We shouldn't be setting conceallevel in the syntax file. Besides not
being able to undo this if we switch to another syntax later, it also
interferes with embedding rust in other filetypes (such as markdown).
Instead, set it in the ftplugin, where it belongs.

These are like the existing bsearch methods but if the search fails,
it returns the next insertion point.
The new `binary_search` returns a `BinarySearchResult` that is either
`Found` or `NotFound`. For convenience, the `found` and `not_found`
methods convert to `Option`, ala `Result`.
Deprecate bsearch and bsearch_elem.
This leaves the `Share` trait at `std::kinds` via a `#[deprecated]` `pub use`

due to #12660 (the build cannot bootstrap otherwise).
All code referencing the `Share` trait should now reference the `Sync` trait,
and all code referencing the `NoShare` type should now reference the `NoSync`
type. The functionality and meaning of this trait have not changed, only the

Previously the implementation detection regex would detect
`impl fmt::Show for MyStruct` as `fmt`. Now it will be detected as
`fmt::Show for MyStruct`. Implementations such as `impl MyStruct` will
still be detected as `MyStruct`.
This adds a new `Recompositions` iterator, which performs canonical composition on the result of the `Decompositions` iterator (which is canonical or compatibility decomposition). In effect this implements Unicode normalization forms C and KC.

Here’s what the Vim manual says in *:syn-include*:
:sy[ntax] include [@{grouplist-name}] {file-name}
All syntax items declared in the included file will have the
"contained" flag added. In addition, if a group list is
specified, all top-level syntax items in the included file will
be added to that list.
We had two rules for `rustModPath`, one `contained` and the other not.
The effect was that the second (now renamed to `rustModPathInUse`) was
being included in the group list, and thus that all identifiers were
being highlighted as `Include`, which is definitely not what we wanted.
This PR adds the LLDB autotests to the debuginfo test suite so I don't have to keep rebasing them locally. They are still disabled by default in `tests.mk`. One of the commits also contains a Python pretty printer which can make LLDB print values with Rust syntax. This was mainly added to deal with output format differences between LLDB versions but you can also use it for your normal LLDB debugging sessions.
```
// The following LLDB commands will load and activate the Rust printers
command script import ./src/etc/lldb_rust_formatters.py
type summary add --no-value --python-function lldb_rust_formatters.print_val -x .* --category Rust
type category enable Rust

- Graphemes and GraphemeIndices structs implement iterators over
grapheme clusters analogous to the Chars and CharOffsets for chars in
a string. Iterator and DoubleEndedIterator are available for both.
- tidied up the exports for libunicode. crate root exports are now moved
into more appropriate module locations:
- UnicodeStrSlice, Words, Graphemes, GraphemeIndices are in str module
- UnicodeChar exported from char instead of crate root
- canonical_combining_class is exported from str rather than crate root
Since libunicode's exports have changed, programs that previously relied
on the old export locations will need to change their `use` statements
to reflect the new ones. See above for more information on where the new
exports live.

Add libunicode; move unicode functions from core
- created new crate, libunicode, below libstd
- split `Char` trait into `Char` (libcore) and `UnicodeChar` (libunicode)

`is_uppercase`, `is_whitespace`, `is_alphanumeric`, `is_control`, `is_digit`,
`to_uppercase`, `to_lowercase`
- added `width` method in UnicodeChar trait
- determines printed width of character in columns, or None if it is a non-NULL control character
- takes a boolean argument indicating whether the present context is CJK or not (characters with 'A'mbiguous widths are double-wide in CJK contexts, single-wide otherwise)
- split `StrSlice` into `StrSlice` (libcore) and `UnicodeStrSlice` (libunicode)
- functionality formerly in `StrSlice` that relied upon Unicode functionality from `Char` is now in `UnicodeStrSlice`
- `words`, `is_whitespace`, `is_alphanumeric`, `trim`, `trim_left`, `trim_right`
- also moved `Words` type alias into libunicode because `words` method is in `UnicodeStrSlice`
- unified Unicode tables from libcollections, libcore, and libregex into libunicode
- updated `unicode.py` in `src/etc` to generate aforementioned tables
- generated new tables based on latest Unicode data
- added `UnicodeChar` and `UnicodeStrSlice` traits to prelude
- libunicode is now the collection point for the `std::char` module, combining the libunicode functionality with the `Char` functionality from libcore
- thus, moved doc comment for `char` from `core::char` to `unicode::char`
- libcollections remains the collection point for `std::str`
The Unicode-aware functions that previously lived in the `Char` and `StrSlice` traits are no longer available to programs that only use libcore. To regain use of these methods, include the libunicode crate and `use` the `UnicodeChar` and/or `UnicodeStrSlice` traits:
extern crate unicode;

The latest change to aturon/rust-guidelines states that lines must not
exceed 99 characters. This gets rid of the 80/100 split, so we don't
need to customize colorcolumn amymore.
Setting softtabstop makes <Del> delete 4 spaces as if it were a tab.
Setting textwidth allows comments to be wrapped automatically. It's set
at 80, which is the recommended line length for Rust programs. There are
suggestions that it should be 79, but our current style guide says 80 so
that's what we're matching.
A new setting g:rust_colorcolumn sets colorcolumn as well, to +1,101.
This indicates both the textwidth and the second stricter line length of
100 that our style guide lists.

This commit is the final step in the libstd facade, #13851. The purpose of this
commit is to move libsync underneath the standard library, behind the facade.
This will allow core primitives like channels, queues, and atomics to all live
in the same location.
There were a few notable changes and a few breaking changes as part of this
movement:
* The `Vec` and `String` types are reexported at the top level of libcollections
* The `unreachable!()` macro was copied to libcore
* The `std::rt::thread` module was moved to librustrt, but it is still
reexported at the same location.
* The `std::comm` module was moved to libsync
* The `sync::comm` module was moved under `sync::comm`, and renamed to `duplex`.
It is now a private module with types/functions being reexported under
`sync::comm`. This is a breaking change for any existing users of duplex
streams.
* All concurrent queues/deques were moved directly under libsync. They are also
all marked with #![experimental] for now if they are public.
* The `task_pool` and `future` modules no longer live in libsync, but rather
live under `std::sync`. They will forever live at this location, but they may
move to libsync if the `std::task` module moves as well.

Attempt to highlight the placement expression in a `box (expr) foo`
expression. Also treat GC as a keyword within the placement expression.
This doesn't work correctly for arbitrary expressions. Notably, this
makes no attempt at balancing delimiters. I believe handling that will
require rewriting the syntax rules to add a region for every pair of
delimiters. That may be a desirable thing to do in the end, because we
can then rewrite our indent rules based on the syntax and get rid of
cindent(), but for the time being, we'll just live with the limitation.
Two line summary: Distinguish HOST_RPATH and TARGET_RPATH; added
RPATH_LINK_SEARCH; skip tests broken in stage1; general cleanup.
`HOST_RPATH_VAR$(1)_T_$(2)_H_$(3)` and `TARGET_RPATH_VAR$(1)_T_$(2)_H_$(3)`
both match the format of the old `RPATH_VAR$(1)_T_$(2)_H_$(3)` (which
is still being set the same way that it was before, to one of either
HOST/TARGET depending on what stage we are building). Namely, the format
is <XXX>_RPATH_VAR = "<LD_LIB_PATH_ENVVAR>=<COLON_SEP_PATH_ENTRIES>"
What this commit does:
* Pass both of the (newly introduced) HOST and TARGET rpath setup vars
to `maketest.py`
* Update `maketest.py` to no longer update the LD_LIBRARY_PATH itself
Instead, it passes along the HOST and TARGET rpath setup vars in
environment variables `HOST_RPATH_ENV` and `TARGET_RPATH_ENV`
* Also, pass the current stage number to maketest.py; it in turn
passes it (via an env var) to run-make tests.
This allows the run-make tests to selectively change behavior
(e.g. turn themselves off) to deal with incompatibilities with
e.g. stage1.
* Cleanup: Distinguish in tools.mk between the command to run (`RUN`)
and the file to generate to drive that command (`RUN_BINFILE`). The
main thing this enables is that `RUN` can now setup the
`TARGET_RPATH_ENV` without having to dirty up the runner code in
each of the `run-make` Makefiles.
* Cleanup: Factored out commands to delete dylib/rlib into
REMOVE_DYLIBS/REMOVE_RLIBS.
There were places where we were only calling `rm $(call DYLIB,foo)`
even though we really needed to get rid of the whole glob (at least
based on alex's findings on #13753 that removing the symlink does not
suffice).
Therefore rather than peppering the code with the awkward
`rm $(TMPDIR)/$(call DYLIB_GLOB,foo)`, I instead introduced a common
`REMOVE_DYLIBS` user function that expands into that when called.
After I adding an analogous `REMOVE_RLIBS`, I changed all of the
existing calls that rm dylibs or rlibs to use these routines
instead.
Note that the latter is not a true refactoring since I may have
changed cases where it was our intent to only remove the sym-link.
(But if that is the case, then we need to more deeply investigate
alex's findings on #13753 where the system was still dynamically
loading up the non-symlinked libraries that it finds on the load
path.)
* Added RPATH_LINK_SEARCH command and use it on Linux.
On some platforms, namely Linux, when you have libboot.so that has
its internal rpath set (to e.g. $(ORIGIN)/path/to/HOSTDIR), the
linker still complains when you do the link step and it does not
know where to find libraries that libboot.so depends upon that live
in HOSTDIR (think e.g. librustuv.so).
As far as I can tell, the GNU linker will consult the
LD_LIBRARY_PATH as part of the linking process to find such
libraries. But if you want to be more careful and not override
LD_LIBRARY_PATH for the `gcc` invocation, then you need some other
way to tell the linker where it can find the libraries that
libboot.so needs. The solution to this on Linux is the
`-Wl,-rpath-link` command line option.
However, this command line option does not exist on Mac OS X, (which
appears to be figuring out how to resolve the libboot.dylib
dependency by some other means, perhaps by consulting the rpath
setting within libboot.dylib).
So, in order to abstract over this distinction, I added the
RPATH_LINK_SEARCH macro to the run-make infrastructure and added
calls to it where necessary to get Linux working. On architectures
other than Linux, the macro expands to nothing.
* Disable miscellaneous tests atop stage1.
* An especially interesting instance of the previous bullet point:
Excuse regex from doing rustdoc tests atop stage1.
This was a (nearly-) final step to get `make check-stage1` working
again.
The use of a special-case check for regex here is ugly but is
analogous other similar checks for regex such as the one that landed
in PR #13844.
The way this is written, the user will get a reminder that
doc-crate-regex is being skipped whenever their rules attempt to do
the crate documentation tests. This is deliberate: I want people
running `make check-stage1` to be reminded about which cases are
being skipped. (But if such echo noise is considered offensive, it
can obviously be removed.)
* Got windows working with the above changes.
This portion of the commit is a cleanup revision of the (previously
mentioned on try builds) re-architecting of how the LD_LIBRARY_PATH
setup and extension is handled in order to accommodate Windows' (1.)
use of `$PATH` for that purpose and (2.) use of spaces in `$PATH`
entries (problematic for make and for interoperation with tools at
the shell).
* In addition, since the code has been rearchitected to pass the
HOST_RPATH_DIR/TARGET_RPATH_DIR rather than a whole sh
environment-variable setting command, there is no need to for the
convert_path_spec calls in maketest.py, which in fact were put in
place to placate Windows but were now causing the Windows builds to
fail. Instead we just convert the paths to absolute paths just like
all of the other path arguments.
Also, note for makefile hackers: apparently you cannot quote operands
to `ifeq` in Makefile (or at least, you need to be careful about
adding them, e.g. to only one side).
There's no need to include this specific flag just for android. We can
already deal with what it tries to solve by using -C linker=/path/to/cc
and -C ar=/path/to/ar. The Makefiles for rustc already set this up when
we're crosscompiling.
I did add the flag to compiletest though so it can find gdb. Though, I'm
pretty sure we don't run debuginfo tests on android anyways right now.
