Summary:
Previously, `google-readability-casting` was disabled for Objective-C.
The Google Objective-C++ style allows both Objective-C and
C++ style in the same file. Since clang-tidy doesn't have a good
way to allow multiple styles per file, this disables the
check for Objective-C++.
Test Plan: New tests added. Ran tests with:
% make -j16 check-clang-tools
Before diff, confirmed tests failed:

And add tests for the comment extraction code.
clangd will now show non-doxygen comments in completion for results
coming from Sema and Dynamic index.
Static index does not include the comments yet, I will enable it in
a separate commit after investigating which implications it has for
the size of the index.

Summary:
Previous implementation used to extract brief text from doxygen comments.
Brief text parsing slows down completion and is not suited for
non-doxygen comments.
This commit switches to providing comments that mimic the ones
originally written in the source code, doing minimal reindenting and
removing the comments markers to make the output more user-friendly.
It means we lose support for doxygen-specific features, e.g. extracting
brief text, but provide useful results for non-doxygen comments.
Switching the doxygen support back is an option, but I suggest to see
whether the current approach gives more useful results.

Summary:
Code completion scoring was embedded in CodeComplete.cpp, which is bad:
- awkward to test. The mechanisms (extracting info from index/sema) can be
unit-tested well, the policy (scoring) should be quantitatively measured.
Neither was easily possible, and debugging was hard.
The intermediate signal struct makes this easier.
- hard to reuse. This is a bug in workspaceSymbols: it just presents the
results in the index order, which is not sorted in practice, it needs to rank
them!
Also, index implementations care about scoring (both query-dependent and
independent) in order to truncate result lists appropriately.
The main yak shaved here is the build() function that had 3 variants across
unit tests is unified in TestTU.h (rather than adding a 4th variant).

That broke every single .clang-tidy config out there
which happened to specify AnalyzeTemporaryDtors option:
YAML:5:24: error: unknown key 'AnalyzeTemporaryDtors'
AnalyzeTemporaryDtors: false
^~~~~
Error parsing <...>/.clang-tidy: Invalid argument
More so, that error isn't actually a error, the
clang-tidy does not exit with $? != 0, it continues
with the default config.
Surely this breakage isn't the intended behavior.
But if it is, feel free to revert this commit.
llvm-svn: 331822
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.

This macro is widely used in many well-known projects, ex. Chromium.
But it's not set for clang-tidy, so for ex. DCHECK in Chromium is not considered

http://google.github.io/styleguide/cppguide.html#64-bit_Portability
This diff relaxes the check to not fire on parameters to functions
with the `__format__` attribute. (I didn't specifically check
for `__printf__` since there are a few variations.)

Summary:
This patch adds index support for GoToDefinition -- when we don't get the
definition from local AST, we query our index (Static&Dynamic) index to
get it.
Since we currently collect top-level symbol in the index, it doesn't support all
cases (e.g. class members), we will extend the index to include more symbols in
the future.

llvm-svn: 331189
Summary:
The Language Server Protocol unfortunately mandates that locations in files
be represented by line/column pairs, where the "column" is actually an index
into the UTF-16-encoded text of the line.
(This is because VSCode is written in JavaScript, which is UTF-16-native).
Internally clangd treats source files at UTF-8, the One True Encoding, and
generally deals with byte offsets (though there are exceptions).
Before this patch, conversions between offsets and LSP Position pretended
that Position.character was UTF-8 bytes, which is only true for ASCII lines.
Now we examine the text to convert correctly (but don't actually need to
transcode it, due to some nice details of the encodings).
The updated functions in SourceCode are the blessed way to interact with
the Position.character field, and anything else is likely to be wrong.
So I also updated the other accesses:
- CodeComplete needs a "clang-style" line/column, with column in utf-8 bytes.
This is now converted via Position -> offset -> clang line/column
(a new function is added to SourceCode.h for the second conversion).
- getBeginningOfIdentifier skipped backwards in UTF-16 space, which is will
behave badly when it splits a surrogate pair. Skipping backwards in UTF-8
coordinates gives the lexer a fighting chance of getting this right.
While here, I clarified(?) the logic comments, fixed a bug with identifiers
containing digits, simplified the signature slightly and added a test.
This seems likely to cause problems with editors that have the same bug, and
treat the protocol as if columns are UTF-8 bytes. But we can find and fix those.
