This reverts commit e2a885537f11f8d9ced1c80c2c90069ab5adeb1d. Build failures were fixed right away and reverting the original commit without the fixes breaks the build again.
The `DiagnosticOptions` class is currently intrusively
reference-counted, which makes reasoning about its lifetime very
difficult in some cases. For example, `CompilerInvocation` owns the
`DiagnosticOptions` instance (wrapped in `llvm::IntrusiveRefCntPtr`) and
only exposes an accessor returning `DiagnosticOptions &`. One would
think this gives `CompilerInvocation` exclusive ownership of the object,
but that's not the case:
```c++
void shareOwnership(CompilerInvocation &CI) {
llvm::IntrusiveRefCntPtr<DiagnosticOptions> CoOwner = &CI.getDiagnosticOptions();
// ...
}
```
This is a perfectly valid pattern that is being actually used in the
codebase.
I would like to ensure the ownership of `DiagnosticOptions` by
`CompilerInvocation` is guaranteed to be exclusive. This can be
leveraged for a copy-on-write optimization later on. This PR changes
usages of `DiagnosticOptions` across `clang`, `clang-tools-extra` and
`lldb` to not be intrusively reference-counted.
With the --force (or -f) option, git-clang-format wipes out input files
excluded by a .clang-format-ignore file if they have unstaged changes.
This patch adds a hidden clang-format option --list-ignored that lists
such excluded files for git-clang-format to filter out.
Fixes#102459.
To support auto-conversion on z/OS text files need to be opened as text files. These changes will fix a number of LIT failures due to text files not being converted to the internal code page.
update a number of tools so they open the text files as text files
add support in the cat.py to open a text file as a text file (Windows will continue to treat all files as binary so new lines are handled correctly)
add env var definitions to enable auto-conversion in the lit config file.
At the moment clang-format will return exit code 0 on incomplete
results. In scripts it would sometimes be useful if clang-format would
instead fail in those cases, signalling that there was something wrong
with the code being formatted.

We should use a tool like Visual Studio to clean up the headers.
Commit d813af73f70f addressed a regression introduced by commit
3791b3fca6ea
but caused `clang-format -dump-config` to "hang".
This patch reverts changes to ClangFormat.cpp by both commits and
reworks the cleanup.
Fixes#80621.
The code cleanup in #74794 accidentally broke detection of languages by
reading file content from stdin, e.g. via `clang-format -dump-config - <
/path/to/filename`.
This PR adds unit and integration tests to reproduce the issue and adds
a fix.
Fixes: #79023
(42ec976184ac was reverted by 26993f61673e due to a use-after-scope bug.)
Reuse the patterns governing the previous input file being formatted if
the current input file is from the same directory.

Relevant issue: https://github.com/llvm/llvm-project/issues/52705
When the `DisableFormat` option of `clang-format` is set to `true` and a JSON file is formatted, the ephemeral variable binding that is added to the top-level object is not removed from the formatted file. For example, this JSON:
```
{
"key": "value"
}
```
Is reformatted to:
```
x = {
"key": "value"
}
```
Which is not valid JSON syntax. This fix avoids the addition of this binding when `DisableFormat` is set to `true`, ensuring that it cannot be left behind when formatting is disabled.

This is a bug which gets reported from time to time and we've had multiple attempts to fix it, but don't want to fix it by adding frontEnd to the mix.
This patch aim to find a trivial, but not that sophisticated way of emitting the error without the additional impact of adding libFrontEnd to clang-format.
See {D90121} for analysis of why we don't want those previous attempts

This change now generates that list, and the change to clang-format allows
us to run clang-format quickly over these files via the list of files.
clang-format.exe -verbose -n --files=./clang/docs/tools/clang-formatted-files.txt
```
Clang-formating 7926 files
Formatting [1/7925] clang/bindings/python/tests/cindex/INPUTS/header1.h
..
Formatting [7925/7925] utils/bazel/llvm-project-overlay/llvm/include/llvm/Config/config.h
```
This is needed because putting all those files on the command line is too
long, and invoking 7900+ clang-formats is much slower (too slow to be honest)
Using this method it takes on 7.5 minutes (on my machine) to run
`clang-format -n` over all of the files (7925), this should result in us
testing any change quickly and easily.
We should be able to use rerunning this list to ensure that we don't regress
clang-format over a large code base, but also use it to ensure none of the
previous files which were 100% clang-formatted remain so.
(which the LLVM premerge checks should be enforcing)

Developers these days seem to argue over east vs west const like they used to argue over tabs vs whitespace or the various bracing style. These previous arguments were mainly eliminated with tools like `clang-format` that allowed those rules to become part of your style guide. Anyone who has been using clang-format in a large team over the last couple of years knows that we don't have those religious arguments any more, and code reviews are more productive.

The purpose of this revision is to try to do the same for the East/West const discussion. Move the debate into the style guide and leave it there!
In addition to the new `ConstStyle: Right` or `ConstStyle: Left` there is an additional command-line argument `--const-style=left/right` which would allow an individual developer to switch the source back and forth to their own style for editing, and back to the committed style before commit. (you could imagine an IDE might offer such a switch)
The revision works by implementing a separate pass of the Annotated lines much like the SortIncludes and then create replacements for constant type declarations.

I find as I develop I'm moving between many different languages C++,C#,JavaScript all the time. As I move between the file types I like to keep `clang-format` as my formatting tool of choice. (hence why I initially added C# support in {D58404}) I know those other languages have their own tools but I have to learn them all, and I have to work out how to configure them, and they may or may not have integration into my IDE or my source code integration.
I am increasingly finding that I'm editing additional JSON files as part of my daily work and my editor and git commit hooks are just not setup to go and run [[ https://stedolan.github.io/jq/ | jq ]], So I tend to go to [[ https://jsonformatter.curiousconcept.com/ | JSON Formatter ]] and copy and paste back and forth. To get nicely formatted JSON. This is a painful process and I'd like a new one that causes me much less friction.
This has come up from time to time:

https://stackoverflow.com/questions/35856565/clang-format-a-json-filehttps://bugs.llvm.org/show_bug.cgi?id=18699
I would like to stop having to do that and have formatting JSON as a first class clang-format support `Language` (even if it has minimal style settings at present).
This revision adds support for formatting JSON using the inbuilt JSON serialization library of LLVM, With limited control at present only over the indentation level
This adds an additional Language into the .clang-format file to separate the settings from your other supported languages.

As noted in https://reviews.llvm.org/D86137#2460135 parsing of
the clang-format parameter -Wno-error=unknown fails.
This currently is done by having `-Wno-error=unknown` as an option.
In this patch this is changed to make `-Wno-error=` parse an enum into a bit set.
This way the parsing is fixed and also we can possibly add new options easily.
