Johan Vikstrom d73d994746 [clangd] Added semantic highlighting support for primitives.
Summary:
Adds a new HighlightingKind "Primitive". Adds a special case for TypeLocs that have an underlying TypePtr that is are builtin types, adding them as primitives.
The primary reason for this change is because otherwise typedefs that typedef primitives `typedef int A` would not get highlighted (so in the example `A` would not get any highlightings.)

Johan Vikstrom b865d5a425 [clangd] Added an early return from VisitMemberExpr in SemanticHighlighting if underlying MemberDecl is a CXXConversionDecl.
Summary:
Conversion operators contain invalid MemberLocs which caused SemanticHighlighting
to emit a lot of error logs in large files as they can occur fairly
often (for example converting StringRef to std string).
As the only thing happening was a lot of error logs being
emited there doesn't really seem to be any way to test this
(no erroneous tokens are added). But emiting as many logs as
were being emited is not wanted.

This also adds a test to guard against regressions for highlightings
disapearing from places where the conversion operators are used as their
behaviour differ from the other CXXMethodDecls.

Johan Vikstrom 720d19b175 [clangd] Fix implicit template instatiations appearing as topLevelDecls.
Summary: The parser gives implicit template instantiations to the action's HandleTopLevelDecls callback. This makes semantic highlighting highlight these templated functions multiple times. Fixed by filtering on if a Decl is an implicit function/variable/class instantiation. Also added a testcase to semantic highlighting on this.

Ilya Biryukov 56bdb0c508 [clangd] Compute scopes eagerly in IncludeFixer
Summary:
Computing lazily leads to crashes. In particular, computing scopes may
produce diagnostics (from inside template instantiations) and we
currently do it when processing another diagnostic, which leads to
crashes.

Moreover, we remember and access 'Scope*' when computing scopes. This
might lead to invalid memory access if the Scope is deleted by the time
we run the delayed computation. We did not actually construct an example
when this happens, though.

From the VCS and review history, it seems the optimization was
introduced in the initial version without a mention of any performance
benchmarks justifying the performance gains. This led me to a
conclusion that the optimization was premature, so removing it to avoid
crashes seems like the right trade-off at that point.

Diego Astiazaran 15e468e0d5 [clang-doc] Fix link generation
Before making a link to a reference it is required to check that the
reference has a path (eg. primitives won't have paths).
This was done by checking if the path was empty; that worked because
when generating paths the outdirectory was included, so if the path was
assigned it had that outdirectory at least.
The path generation was changed, it's now only the composite of the
namespaces without the outdirectory. So if the info is in the global
namespace the path would be empty and the old check wouldn't work as expected.
A new attribute has been added to the Reference struct that indicates if
the info's parent is the global namespace.
Paths generation now fails if the path is empty and if the info
is not in the global namespace.

Sam McCall ac7864ec01 [clangd] Add new helpers to make tweak tests scale better. Convert most tests. NFC
Summary:
TweakTests.cpp has some pretty good helpers added for the first few
tweaks, but they have some limitations:
 - many assertion failures point at the wrong line
 - need lots of input/output tests, setup code is duplicated across both
 - local helpers make it hard to split the file as it grows

The new helpers in TweakTests.h are based on old ones (same operations)
but try to address these issues and generally make tests more terse
while improving error messages.

This patch converts everything except ExtractVariable (which is complex
and has changes in flight, so will be converted later).
It's LOC-neutral, despite not being able to get rid of the old helpers
until ExtractVariable is done.

Sam McCall abe3c29a8c [clangd] Ignore semicolons, whitespace, and comments in SelectionTree.
Summary:
Whitespace and comments are a clear bugfix: selecting some
comments/space near a statement doesn't mean you're selecting the
surrounding block.

Semicolons are less obvious, but for similar reasons: these tokens
aren't actually claimed by any AST node (usually), so an AST-based model
like SelectionTree shouldn't take them into account.

Callers may still sometimes care about semis of course:
 - when the selection is an expr with a non-expr parent, selection of
   the semicolon indicates intent to select the statement.
 - when a statement with a trailing semi is selected, we need to know
   its range to ensure it can be removed.
SelectionTree may or may not play a role here, but these are separate questions
from its core function of describing which AST nodes were selected.

The mechanism here is the TokenBuffer from syntax-trees. We use it in a
fairly low-level way (just to get boundaries of raw spelled tokens). The
actual mapping of AST nodes to coordinates continues to use the (fairly
mature) SourceLocation based logic. TokenBuffer/Syntax trees
don't currently offer an alternative to getFileRange(), I think.

Summary:
Now that clang is going to be able to build the Linux kernel again on
x86, and we have gen_compile_commands.py upstream for generating
compile_commands.json, clang-tidy can be used on the Linux kernel
source.

To that end, this commit adds a new clang-tidy module to be used for
checks specific to Linux kernel source. The Linux kernel follows its own
style of C, and it will be useful to separate those checks into their
own module.

This also adds an initial check that makes sure that return values from
the kernel error functions like PTR_ERR and ERR_PTR are checked. It also
makes sure that any functions that directly return values from these
functions are checked.

Haojian Wu 18fa729a39 [clangd] Fix the annotate tweak after rL366893
Summary:
After rL366893, the annoate tweak is not activated when we select the
whole file (the commonAncestor is TUDecl but we intend to return null).

This patch fixes this, and also avoid traversing the TUDecl.

Sam McCall 8faffec4e2 [clangd] Also accept flags from CLANGD_FLAGS variable.
This simplifies various workflows, particularly in debugging/development.
e.g. editors will tend to propagate flags, so you can run
`env CLANGD_FLAGS=-input-mirror-file=/tmp/mirror vim foo.cc` rather than
change the configuration in a persistent way.
(This also gives us a generic lever when we don't know how to customize
the flags in some particular LSP client).

While here, add a test for this and other startup logging, and fix a
couple of direct writes to errs() that should have been logs.

While here, remove `static` from the opts in favor of an anon namespace, to

Sam McCall bdc6b6e410 [clangd] SelectionTree treats TranslationUnitDecl (mostly) consistently with other containers.
Summary:
Previously TranslationUnitDecl would never be selected.
This means root() is never null, and returns a reference.

commonAncestor() is in principle never null also, but returning TUDecl
here requires tweaks to be careful not to traverse it (this was already
possible when selecting multiple top-level decls, and there are associated bugs!)
Instead, never allow commonAncestor() to return TUDecl, return null instead.

Sam McCall 7fc8f415ea [clangd] Add dlog()s for SelectionTree, enabling -debug-only=SelectionTree.cpp
Summary:
SelectionTree is a RecursiveASTVisitor which processes getSourceRange() for
every node. This is a lot of surface area with the AST, as getSourceRange()
is specialized for *many* node types.
And the resulting SelectionTree depends on the source ranges of many
visited nodes, and the order of traversal.

Put together, this means we really need a traversal log to debug when we
get an unexpected SelectionTree. I've built this ad-hoc a few times, now
it's time to check it in.

Example output:
```
D[14:07:44.184] Computing selection for </usr/local/google/home/sammccall/test.cc:1:7, col:8>

Kadir Cetinkaya 006d1915e2 [clangd] BackgroundIndex stores shards to the closest project
Summary:
Changes persistance logic to store shards at the directory of closest
CDB. Previously we were storing all shards to directory of the CDB that
triggered indexing, it had its downsides.

For example, if you had two TUs coming from a different CDB but depending on the
same header foo.h, we will store the foo.h only for the first CDB, and it would
be missing for the second and we would never persist it since it was actually
present in the memory and persisted before.

This patch still stores only a single copy of a shard, but makes the directory a
function of the file name. So that the shard place will be unique even with
multiple CDBs accessing the file. This directory is determined as the first
directory containing a CDB in the file's parent directories, if no such
directory exists we make use of the home directory.

I have run this check (repeatedly) over llvm-project. It made 1708 member functions
``static``. Out of those, I had to exclude 22 via ``NOLINT`` because their address
was taken and stored in a variable of pointer-to-member type (e.g. passed to
llvm::StringSwitch).
It also made 243 member functions ``const``. (This is currently very conservative
to have no false-positives and can hopefully be extended in the future.)

Sam McCall 9470142ca5 [clangd] Implementation of auto type expansion.
Add a tweak for clangd to replace an auto keyword to the deduced type.

This way a user can declare something with auto and then have the
IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
user.

The functionality is similar to the hover over the auto keyword.

Example (from the header):

```
/// Before:
///    auto x = Something();
///    ^^^^
/// After:
///    MyClass x = Something();
///    ^^^^^^^

Don Hinton 43d75f9778 Recommit "[CommandLine] Remove OptionCategory and SubCommand caches from the Option class."
Previously reverted in 364141 due to buildbot breakage, and fixed here
by making GeneralCategory global a ManagedStatic.

Summary:
This change processes `OptionCategory`s and `SubCommand`s as they
are seen instead of caching them in the Option class and processing
them later.  Doing so simplifies the work needed to be done by the Global
parser and significantly reduces the size of the Option class to a mere 64
bytes.

Removing  the `OptionCategory` cache saved 24 bytes, and removing
the `SubCommand` cache saved an additional 48 bytes, for a total of a
72 byte reduction.

Sam McCall 2f760c44e6 [clangd] Rewrite of logic to rebuild the background index serving structures.
Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.

 - rebuilds are triggered by #TUs built, rather than time. This should scale
   more sensibly to fast vs slow machines.
 - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
   for the first build, 100 for subsequent rebuilds.
 - rebuild is always done on the regular indexing threads, and is affected by
   blockUntilIdle. This means unit/lit tests run the production configuration.
 - fixed a bug where we'd rebuild after attempting to load shards, even if there
   were no shards.
 - the BackgroundIndexTests don't really test the subtleties of the rebuild
   policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
   to pass the tests). Instead, we expose the rebuilder as a separate class and
   have fine-grained tests for it.

Sam McCall 674d8a947c [clangd] Use xxhash instead of SHA1 for background index file digests.
Summary:
Currently SHA1 is about 10% of our CPU, this patch reduces it to ~1%.

xxhash is a well-defined (stable) non-cryptographic hash optimized for
fast checksums (like crc32).
Collisions shouldn't be a problem, despite the reduced length:
 - for actual file content (used to invalidate bg index shards), there
   are only two versions that can collide (new shard and old shard).
 - for file paths in bg index shard filenames, we would need 2^32 files
   with the same filename to expect a collision. Imperfect hashing may
   reduce this a bit but it's well beyond what's plausible.

This will invalidate shards on disk (as usual; I bumped the version),
but this time the filenames are changing so the old files will stick
around :-( So this is more expensive than the usual bump, but would be
good to land before the v9 branch when everyone will start using bg index.

Bjorn Pettersson 009225374a Bitstream reader: Fix undefined behavior seen after rL364464
Summary:
After rL364464 the following tests started to fail when
running the clang-doc tests with an ubsan instrumented
build of clang-doc:
    Clang Tools :: clang-doc/single-file-public.cpp
    Extra Tools Unit Tests :: clang-doc/./ClangDocTests/BitcodeTest.emitEnumInfoBitcode
    Extra Tools Unit Tests :: clang-doc/./ClangDocTests/BitcodeTest.emitMethodInfoBitcode
    Extra Tools Unit Tests :: clang-doc/./ClangDocTests/BitcodeTest.emitRecordInfoBitcode
    Extra Tools Unit Tests :: clang-doc/./ClangDocTests/SerializeTest.emitInfoWithCommentBitcode

We need to check that the read value is in range for being
casted to the llvm::bitc::FixedAbbrevIDs enum, before the
cast in ClangDocBitcodeReader::skipUntilRecordOrBlock.

SerializedDiagnosticReader::skipUntilRecordOrBlock was updated
in the same way.

Francis Visoiu Mistrih e0308279cb [Bitcode] Move Bitstream to a separate library
This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/.

This is needed to avoid a circular dependency when using the bitstream
code for parsing optimization remarks.

Since Bitcode uses Core for the IR part:

libLLVMRemarks -> Bitcode -> Core

and Core uses libLLVMRemarks to generate remarks (see
IR/RemarkStreamer.cpp):

Core -> libLLVMRemarks

we need to separate the Bitstream and Bitcode part.

For clang-doc, it seems that it doesn't need the whole bitcode layer, so
I updated the CMake to only use the bitstream part.

Haojian Wu 7c251fa069 [clangd] Collect the refs when the main file is header.
Summary:
Previously, we only collect refs of the symbols which are declared in
the preamble and referenced in the main file, it works well when the
main file is .cpp file.

However, when the main file is .h file (when opening a .h file in the
editor), we don't collect refs of the symbol declared in this file, so we miss
these refs in our dynamic index.

A typical scenario:

1. Open Foo.h (which contains class Foo)
2. Open Foo.cpp, call find references for Foo

And we only get refs from Foo.cpp.

Sam McCall 9cca81344c [clangd] Make PreambleStatusCache handle filenames more carefully
Summary:
 - when we hit the cache, the reported filename should be that of the

   common FSes, and avoids triggering difficult edge cases in
   FileManager when files are being moved around concurrently.
 - filename comparisons (both cache queries and == mainfile checks)
   should fold away . and .. in paths. These can appear when relative
   paths occur in compile_commands.json. (gn does this).
