We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Add a way to expand modular headers for PPCallbacks. Checks can opt-in for this

registering their PPCallbacks in the preprocessor created for this specific
purpose.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Currently ClangTidyContext::diag() sends the diagnostics to a
DiagnosticsEngine, which probably delegates to a ClangTidyDiagnosticsConsumer,
which is supposed to go back and populate ClangTidyContext::Errors.
After this patch, the diagnostics are stored in the ClangTidyDiagnosticsConsumer
itself and can be retrieved from there.
Why?
- the round-trip from context -> engine -> consumer -> context is confusing
and makes it harder to establish layering between these things.
- context does too many things, and makes it hard to use clang-tidy as a library
- everyone who actually wants the diagnostics has access to the ClangTidyDiagnosticsConsumer
The most natural implementation (ClangTidyDiagnosticsConsumer::take()
finalizes diagnostics) causes a test failure: clang-tidy-run-with-database.cpp
asserts that clang-tidy exits successfully when trying to process a file
that doesn't exist.
In clang-tidy today, this happens because finish() is never called, so the
diagnostic is never flushed. This looks like a bug to me.
For now, this patch carefully preserves that behavior, but I'll ping the
authors to see whether it's deliberate and worth preserving.

This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.

$ cat *.json
{
"file": "/path/to/source.cpp",

```
There are two arguments that control profile storage:
* `-store-check-profile=<prefix>`
By default reports are printed in tabulated format to stderr. When this option
is passed, these per-TU profiles are instead stored as JSON.
If the prefix is not an absolute path, it is considered to be relative to the
directory from where you have run :program:`clang-tidy`. All `.` and `..`
patterns in the path are collapsed, and symlinks are resolved.
Example:
Let's suppose you have a source file named `example.cpp`, located in
`/source` directory.
* If you specify `-store-check-profile=/tmp`, then the profile will be saved
to `/tmp/<timestamp>-example.cpp.json`
* If you run :program:`clang-tidy` from within `/foo` directory, and specify
`-store-check-profile=.`, then the profile will still be saved to
`/foo/<timestamp>-example.cpp.json`

Summary: The alpha checkers can already be enabled using the clang driver, this allows them to be enabled using the clang-tidy as well. This can make it easier to test the alpha checkers with projects which already support the compile_commands.json. It will also allow more people to give feedback and patches about the alpha checkers since they can run it as part of clang tidy checks.

Differential Revision: https://reviews.llvm.org/D46159
llvm-svn: 332609
Summary:
As discussed in D45931, currently, profiling output of clang-tidy is somewhat not great.
It outputs one profile at the end of the execution, and that profile contains the data
from the last TU that was processed. So if the tool run on multiple TU's, the data is
not accumulated, it is simply discarded.
It would be nice to improve this.
This differential is the first step - make this profiling info per-TU,
and output it after the tool has finished processing each TU.
In particular, when `ClangTidyASTConsumer` destructor runs.
Next step will be to add a CSV (JSON?) printer to store said profiles under user-specified directory prefix.

Summary:
Rename ChecksFilter to GlobList, as there's nothing specific to checks in it.
It's a rather generic way to represent sets of strings (or patterns), so it may

when used to filter other entities.

Summary:
This patch implements filtering of clang-tidy diagnostic messages by
the check name, so that "clang-tidy -checks=^llvm-" won't output any clang
warnings, for example. This is also helpful to run specific static-analyzer
checks: static analyzer always needs core checks to be enabled, but the user may
be interested only in the checks he asked for.
This patch also exposes warning option names for built-in diagnostics. We need
to have a namespace for these names to avoid collisions and to allow convenient
filtering, so I prefix them with "-W". I'm not sure it's the best thing to do,
and maybe "W" or "clang-diagnostic-" or something like this would be better.
