Refactor `addSyntacticRenameRanges`, adding comments to make it easier to follow and remove its dependency on the `IsFunctionLike` parameter in `RenameLoc`.
We can’t represent the parent node when rewriting `NameMatcher` using swift-syntax. Replace it by two boolean fields `IsComment` and `IsInStringLiteral` that can be bridged.
To match terminology used elsewhere in the compiler (e.g. "parsed accessor")
rename "original attributes" to "parsed atributes". Additionally, make sure the
attributes returned by `getParsedAttrs()` really are just the parsed ones by
skipping implicit attributes in addition to the ones expanded from macros.
In C++20, the compiler will synthesize a version of the operator
with its arguments reversed to ease commutativity. This reversed
version is ambiguous with the hand-written operator when the
argument is const but `this` isn't.
Reformatting everything now that we have `llvm` namespaces. I've
separated this from the main commit to help manage merge-conflicts and
for making it a bit easier to read the mega-patch.
This is phase-1 of switching from llvm::Optional to std::optional in the
next rebranch. llvm::Optional was removed from upstream LLVM, so we need
to migrate off rather soon. On Darwin, std::optional, and llvm::Optional
have the same layout, so we don't need to be as concerned about ABI
beyond the name mangling. `llvm::Optional` is only returned from one
function in
```
getStandardTypeSubst(StringRef TypeName,
bool allowConcurrencyManglings);
```
It's the return value, so it should not impact the mangling of the
function, and the layout is the same as `std::optional`, so it should be
mostly okay. This function doesn't appear to have users, and the ABI was
already broken 2 years ago for concurrency and no one seemed to notice
so this should be "okay".
I'm doing the migration incrementally so that folks working on main can
cherry-pick back to the release/5.9 branch. Once 5.9 is done and locked
away, then we can go through and finish the replacement. Since `None`
and `Optional` show up in contexts where they are not `llvm::None` and
`llvm::Optional`, I'm preparing the work now by going through and
removing the namespace unwrapping and making the `llvm` namespace
explicit. This should make it fairly mechanical to go through and
replace llvm::Optional with std::optional, and llvm::None with
std::nullopt. It's also a change that can be brought onto the
release/5.9 with minimal impact. This should be an NFC change.
It doesn't seem like there's any client that's
actually taking advantage of setting it to `false`,
and its default value of `false` is more likely
than not going to cause clients to accidentally
miss comments that they may want. In fact, this
was exactly the case for code completion's brief
field. Finally, the parameter wasn't even
consistently applied, as we would attempt to
deserialize swiftdoc comments even if it were
`false`.
Various requests expect to be walking over the current source file.
While we could add checks to all these to skip decls outside of the
current buffer, it's a little nicer to handle this during the walk
instead.
Allow ignoring nodes that are from macro expansions and add that flag to
the various walks that expect it.
Also add a new `getOriginalAttrs` that filters out attributes in
generated source.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

Replace the use of bool and pointer returns for
`walkToXXXPre`/`walkToXXXPost`, and instead use
explicit actions such as `Action::Continue(E)`,
`Action::SkipChildren(E)`, and `Action::Stop()`.
There are also conditional variants, e.g
`Action::SkipChildrenIf`, `Action::VisitChildrenIf`,
and `Action::StopIf`.
There is still more work that can be done here, in
particular:
- SourceEntityWalker still needs to be migrated.
- Some uses of `return false` in pre-visitation
methods can likely now be replaced by
`Action::Stop`.
- We still use bool and pointer returns internally
within the ASTWalker traversal, which could likely
be improved.
But I'm leaving those as future work for now as
this patch is already large enough.
The removed `else if` branch caused the argument to the `-` operator to be be reported as `Mismatch`. I couldn’t figure out what that branch was for, so I removed it.

This cleans up 90 instances of this warning and reduces the build spew
when building on Linux. This helps identify actual issues when
building which can get lost in the stream of warning messages. It also
helps restore the ability to build the compiler with gcc.
This commit essentially consistes of the following steps:
- Add a new code completion key path component that represents the code completion token inside a key path. Previously, the key path would have an invalid component at the end if it contained a code completion token.
- When type checking the key path, model the code completion token’s result type by a new type variable that is unrelated to the previous components (because the code completion token might resolve to anything).
- Since the code completion token is now properly modelled in the constraint system, we can use the solver based code completion implementation and inspect any solution determined by the constraint solver. The base type for code completion is now the result type of the key path component that preceeds the code completion component.
This resolves bugs where code completion was not working correctly if the key path’s type had a generic base or result type. It’s also nice to have moved another completion type over to the solver-based implementation.

Adapt the `ThrowingEntityAnalyzer` to pick up any
`await` keywords and add an `async` to the extracted
function if necessary along with an `await` for its
call.

Abstract away the TupleExpr gunk and expose
`getLHS` and `getRHS` accessors. This is in
preparation for completely expunging the use
of TupleExpr as an argument list.
This change makes us treat it exactly as we do 'init'. We don't allow renaming the base name,
and don't fail if the basename doesn't match for calls.
Also:
- explicit init calls/references like `MyType.init(42)` are now reported with
'init' as a keywordBase range, rather than nothing.
- cursor info no longer reports rename as available on init/callAsFunction
calls without arguments, as there's nothing to rename in that case.
- Improved detection of when a referenced function is a call (rather than
reference) across syntactic rename, cursor-info, and indexing.

These files were using clang::SourceManager with only a forward declaration.
Most likely another header was previously including the SourceManager header so
that these files got the header included transitively.
SwiftSourceInfo files provide source location information for decls coming from
loaded modules. For most IDE use cases it either has an undesirable impact on
performance with no benefit (code completion), results in stale locations being
used instead of more up-to-date indexer locations (cursor info), or has no
observable effect (live diagnostics, which are filtered to just those with a
location in the primary file).
For non-IDE clients of SourceKit though, cursor info providing declaration
locations for symbols from other modules is useful, so add a global
configuration option (and a new request to set it) to control whether
.swiftsourceinfo files are loaded or not based on use case (they are loaded by
default).
TypeCheckPattern used to splat the interface type into this, and
different parts of the compiler would check one or the other. There is
now one source of truth: The interface type. The type repr is now just
a signal that the user has written an explicit type annotation on
a parameter. For variables, we will eventually be able to just grab
this information from the parent pattern.
