Apply optimization described in
https://github.com/rust-lang/regex/pull/73#issuecomment-93777126
to rust's copy of `unicode.py`.
This shrinks librustc_unicode's tables.rs from 479kB to 456kB,
and should improve performance slightly for related operations
(e.g., is_alphabetic(), is_xid_start(), etc).
In addition, pull in fix from @dscorbett's commit
d25c39f86568a147f9b7080c25711fb1f98f056a in regex, which
makes `load_properties()` more tolerant of whitespace
in the Unicode tables. (This fix does not result in any
changes to tables.rs, but could if the Unicode tables
change in the future.)
This patch
1. renames libunicode to librustc_unicode,
2. deprecates several pieces of libunicode (see below), and
3. removes references to deprecated functions from
librustc_driver and libsyntax. This may change pretty-printed
output from these modules in cases involving wide or combining
characters used in filenames, identifiers, etc.
The following functions are marked deprecated:
1. char.width() and str.width():
--> use unicode-width crate
2. str.graphemes() and str.grapheme_indices():
--> use unicode-segmentation crate
3. str.nfd_chars(), str.nfkd_chars(), str.nfc_chars(), str.nfkc_chars(),
char.compose(), char.decompose_canonical(), char.decompose_compatible(),
char.canonical_combining_class():
--> use unicode-normalization crate
This PR makes `rustc` emit field names for tuple fields in DWARF. Formerly there was no way of directly accessing the fields of a tuple in GDB and LLDB since there is no C/C++ equivalent to this. Now, the debugger sees the name `__{field-index}` for tuple fields. So you can type for example `some_tuple_val.__2` to get the third tuple component.
When pretty printers are used (e.g. via `rust-gdb` or `rust-lldb`) these artificial field names will not clutter tuple rendering (which was the main motivation for not doing this in the past).
Solves #21948.
This commit series starts out with more official test harness support for rustdoc tests, and then each commit afterwards adds a test (where appropriate). Each commit should also test and finish independently of all others (they're all pretty separable).
I've uploaded a [copy of the documentation](http://people.mozilla.org/~acrichton/doc/std/) generated after all these commits were applied, and a double check on issues being closed would be greatly appreciated! I'll also browse the docs a bit and make sure nothing regressed too horribly.
The idea here is if you don't want rust in /usr/local
you can put something like this is your .profile:
```
export RUSTUP_PREFIX=$HOME/.local/rust
export PATH=$PATH:${RUSTUP_PREFIX}/bin
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:${RUSTUP_PREFIX}/lib
```
Then when you run rustup, it will update the install
in ${RUSTUP_PREFIX} without having to remember to pass
an explicit --prefix argument every time.

@mahkoh points out in #15628 that unicode.py does not use
normative data for Grapheme classes. This pr fixes that issue.
In addition, GC_RegionalIndicator is renamed GC_Regional_Indicator
in order to stay in line with the Unicode class name definitions.
I have updated refs in u_str.rs, and verified that there are no
refs elsewhere in the codebase. However, in principle someone
using the unicode tables for their own purposes might see breakage
from this.
Rationale for this, is that I lurked `ulimit -c unlimited` into my .profile to debug an unrelated crash, that I kept forgetting to set before hand. I then ran the test suite and discovered that I had 150 gigs of core dumps in `/cores`.
Very open to another approach, or to setting the limit to something higher than 0, but I think it would be nice if the build system tried to save you from yourself here.
Currently, the list of files linted in `tidy.py` is unordered. It seems more appropriate for more frequently appearing files (like `.rs`) to appear at the top of the list and for \"other files\" to appear at the very end. This PR also changes the wildcard import of `check_license()` into an explicit one.
```
Before: After:
* linted 4 .sh files * linted 5034 .rs files
* linted 4 .h files * linted 29 .c files
* linted 29 .c files * linted 28 .py files
* linted 2 .js files * linted 4 .sh files
* linted 0 other files * linted 4 .h files
* linted 28 .py files * linted 2 .js files
* linted 5034 .rs files * linted 0 other files
```

This changes the type of some public constants/statics in libunicode.
Notably some `&'static &'static [(char, char)]` have changed
to `&'static [(char, char)]`. The regexp crate seems to be the
sole user of these, yet this is technically a [breaking-change]
- Replace wildcard import with explicit import of `check_license`
- Move more logic outside of the `try` block.
- Group all helper functions together.
- Define `interesting_exts` and `uninteresting_files` at start of file
(with the rest of the constant declarations).
Since it makes more sense for .rs files to appear at the top of the
list of linted files and "other" files to appear at the end, this
commit moves the "other" count outside of the `file_counts` dictionary
and sorts the remaining "interesting" files by decreasing frequency.
- Now "make check-stage2-T-aarch64-linux-android-H-x86_64-unknown-linux-gnu" works (#21773)
- Fix & enable debuginfo tests for android (#10381)
- Fix & enable more tests for android (both for arm/aarch64)
- Enable many already-pass tests on android (both for arm/aarch64)
Since `tr` converts lowercase to uppercase according to system locale using `LC_CTYPE` environment variable; on some locales, rustup.sh fails to use correct variables names, thus deletes temporarily downloaded files and gives a meaningless error as shown below. This a simple fix which explictly sets `LC_CTYPE` as `C`.
Here is what happens without the fix:

Notice how `i` wasn't replaced with `I`.
Rust is installed as usual after the fix. Tested on Ubuntu x86 12.04 LTS.
I'm not exactly sure if setting LC_CTYPE is the best solution, but there's that.
The book in "hello-world" tells that there are configs for some programs and gives a link to main repo's src/etc. Actually, these configs moved to separate repos some days ago. This PR adds a markdown file with links and moves "hello-world" link about editors to point directly to this new file.
