* Removes `RustJITMemoryManager` from public API.
This was really sort of an implementation detail to begin with.
* `__morestack` is linked to C++ wrapper code and this pointer
is used when resolving the symbol for `ExecutionEngine` code.
* `__morestack_addr` is also resolved for `ExecutionEngine` code.
This function is sometimes referenced in LLVM-generated code,
but was not able to be resolved on Mac OS systems.
* Added Windows support to `ExecutionEngine` API.
* Added a test for basic `ExecutionEngine` functionality.

This might fail when --extern library is a symlink to an invalid location. Instead just pretend it
doesn’t exist at all.

I've been working on improving the diagnostic registration system so that it can:
* Check uniqueness of error codes *across the whole compiler*. The current method using `errorck.py` is prone to failure as it relies on simple text search - I found that it breaks when referencing an error's ident within a string (e.g. `"See also E0303"`).
* Provide JSON output of error metadata, to eventually facilitate HTML output, as well as tracking of which errors need descriptions. The current schema is:
```
<error code>: {
"description": <long description>,
"use_site": {
"filename": <filename where error is used>,
"line": <line in file where error is used>
}
}
```
[Here's][metadata-dump] a pretty-printed sample dump for `librustc`.
One thing to note is that I had to move the diagnostics arrays out of the diagnostics modules. I really wanted to be able to capture error usage information, which only becomes available as a crate is compiled. Hence all invocations of `__build_diagnostics_array!` have been moved to the ends of their respective `lib.rs` files. I tried to avoid moving the array by making a plugin that expands to nothing but couldn't invoke it in item position and gave up on hackily generating a fake item. I also briefly considered using a lint, but it seemed like it would impossible to get access to the data stored in the thread-local storage.
The next step will be to generate a web page that lists each error with its rendered description and use site. Simple mapping and filtering of the metadata files also allows us to work out which error numbers are absent, which errors are unused and which need descriptions.

Diagnostic errors are now checked for uniqueness across the compiler and
error metadata is written to JSON files.
|
|
Such things no longer exist.

This required fixing the `pretty-rpass-full` tests to have the same `$$(CSREQ$(1)_T_$(2)_H_$(3))` dependencies as the `rpass-full` and `cfail-full` tests. It also required fixing the `run-make/simd-ffi` test to use unique names for its output files.

When linking an archive statically to an rlib, the compiler will extract all
contents of the archive and add them all to the rlib being generated. The
current method of extraction is to run `ar x`, dumping all files into a
temporary directory. Object archives, however, are allowed to have multiple
entries with the same file name, so there is no method for them to extract their
contents into a directory in a lossless fashion.
This commit adds iterator support to the `ArchiveRO` structure which hooks into
LLVM's support for reading object archives. This iterator is then used to
inspect each object in turn and extract it to a unique location for later
assembly.

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 is the second attempt at turning the trace_macros macro into a compiler flag.
See #22619

One of the parameters to the magical "register a thread-local destructor"
function is called `__dso_handle` and largely just passed along (this seems to
be what other implementations do). Currently we pass the *value* of this symbol,
but apparently the correct piece of information to pass is the *address* of the
symbol.
In a PIE binary the symbol actually contains an address to itself which is why
we've gotten away with what we're doing as long as we have. In a non-PIE binary
the symbol contains the address `NULL`, causing a segfault in the runtime
library if it keeps going.
Closes #24445

This seems to fix the test
|
|
This is a little bit tricky, since with include_str!, we know that we
are including utf-8 content, so it's safe to store the source as a
String in a FileMap. We don't know that for include_bytes!, but I don't
think we actually need to track the contents anyways, so I'm passing "".
new_filemap does check for the zero length content, and it should be
reasonable, howeven I'm not sure if it would be better to pass None
instead of Some(Rc::new("")) as the src component of a FileMap.
Fixes bug #24348

It was an oversight that this was not done in the great int upheaval.

This tests that both include_str! and include_bytes! mark their input
file as a dependancy, and it's correctly outputted when you run
`rustc --emit dep-info`.
|
|
It generates a warning that --outdir argument is ignored, which is
captured and spoils the output
Also ensure that test output is captured in a different file than the
expected output file

This commit cleans out a large amount of deprecated APIs from the standard
library and some of the facade crates as well, updating all users in the
compiler and in tests as it goes along.

Pretty much what it says on the tin.
