We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

A user of the check opened a bugreport and reported that `std::exchange`

Summary:
- GlobalCompilationDatabase now returns a single command (that's all we use)
- fallback flags are now part of the GlobalCompilationDatabase.
There's a default implementation that they can optionally customize.
- this allows us to avoid invoking the fallback logic on two separate codepaths
- race on extra flags fixed by locking the mutex
- made GCD const-correct (DBGCD does have mutating methods)

Without specifying the signedness of the underlying type for Action,
packing it in a 1-bit field may restrict its range to [-1, 0] which
can't represent Match.
llvm-svn: 319606
Summary:
This will be used for rescoring code completion results based on partial
identifiers.
Short-term use:
- we want to limit the number of code completion results returned to
improve performance of global completion. The scorer will be used to
rerank the results to return when the user has applied a filter.
Long-term use case:
- ranking of completion results from in-memory index
- merging of completion results from multiple sources (merging usually
works best when done at the component-score level, rescoring the
fuzzy-match quality avoids different backends needing to have
comparable scores)

Summary:
This allows us to limit the number of results we return and still allow them
to be surfaced by refining a query (D39852).
The initial algorithm is very conservative - it accepts a completion if the
filter is any case-insensitive sub-sequence. It does not attempt to rank items
based on match quality.

Summary:
- JSON<->Obj interface is now ADL functions, so they play nicely with enums
- recursive vector/map parsing and ObjectMapper moved to JSONExpr and tested
- renamed (un)parse to (de)serialize, since text -> JSON is called parse
- Protocol.cpp gets a bit shorter

Summary:
This makes the parse() functions about as short as they can be given the
current signature, and moves all array-traversal etc code to a
central location.
We keep the ability to distinguish between optional and required fields:
and we don't propagate parse errors for optional fields.
I've made most fields required per the LSP spec - the looseness we had
here was mostly a historical accident I think.

Summary:
- Converted Protocol.h parse() functions to take JSON::Expr.
These no longer detect and log unknown fields, as this is not that
useful and no longer free.
I haven't changed the error handling too much: fields that were
treated as optional before are still optional, even when it's wrong.
Exception: object properties with the wrong type are now ignored.
- Made JSONRPCDispatcher parse using json::parse
- The bug where 'method' must come before 'params' in the stream is
fixed as a side-effect. (And the same bug in executeCommand).
- Some parser crashers fixed as a side effect.
e.g. https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3890
- The debug stream now prettyprints the input messages with --pretty.
- Request params are attached to traces when tracing is enabled.
- Fixed some bugs in tests (errors tolerated by YAMLParser, and
off-by-ones in Content-Length that our null-termination was masking)
- Fixed a random double-escape bug in ClangdLSPServer (it was our last
use of YAMLParser!)
