Conflicts:
- `CMakeLists.txt` caused by the extra `-D` added in rebranch to
reduce the number of deprecation warnings.
- `lib/Frontend/PrintingDiagnosticConsumer.cpp` caused by the removal
of one of the `#if SWIFT_SWIFT_PARSER` on rebranch (probably should
have been done on main).
Because swift_swap_compiler_if_needed updates the compiler ID to
Clang, we need to account for it when deciding to add a dependency on
clang. Otherwise, the sourcekit build could fail due to the clang
executable not having been built there yet.
Use FetchContent to include swift-syntax directly in swift. This can be
thought of as an `add_subdirectory` for a directory outside the root.
The default build directory will be `_deps/swiftsyntax-subbuild/`, though
the modules and shared libraries will be built in `lib/swift/host` by
passing down `SWIFT_HOST_LIBRARIES_DEST_DIR` to avoid copying them as we
were doing previously.
Account for import libraries and the associated layout difference on
platforms (e.g. DLLs are placed in `bin`). This is required to enable
building the macro path on Windows.
Wrap the `InheritedEntry` array available on both `ExtensionDecl` and
`TypeDecl` in a new `InheritedTypes` class. This class will provide shared
conveniences for working with inherited type clauses. NFC.
interface for index.
An explicit module build compile is unable to do so because it does not have
access to the interfaces. Doing this in the first place is a workaround for a
known bug, which will require to be solved at the root cause instead (e.g.
Deserialization Safety feature).

and Swift parser integration is enabled.
If swift parser integration is enabled, SwiftSyntax libraries are always
built with host tools. Other SwiftCompilerSources modules must use the
same runtime with parser libraries.
For compiling codes required for macro support, we now need swiftc
compiler in the build machine.
Unlike Darwin OSes, where swiftCore runtime is guaranteed to be present
in /usr/lib, Linux doesn't have ABI stability and the stdlib of the
build machine is not at the specific location. So the built compiler
cannot relies on the shared object in the toolchain.
Pointer `llvm/Support/Host.h` at `llvm/TargetParser/Host.h`.
Replacing deprecated API `startswith_insensitive` with replacement

As of CMake 3.25, there are now global variables `LINUX=1`, `ANDROID=1`,
etc. These conflict with expressions that used these names as unquoted
strings in positions where CMake accepts 'variable|string', for example:
- `if(sdk STREQUAL LINUX)` would fail, because `LINUX` is now defined and
expands to 1, where it would previously coerce to a string.
- `if(${sdk} STREQUAL "LINUX")` would fail if `sdk=LINUX`, because the
left-hand side expands twice.
In this patch, I looked for a number of patterns to fix up, sometimes a
little defensively:
- Quoted right-hand side of `STREQUAL` where I was confident it was
intended to be a string literal.
- Removed manual variable expansion on left-hand side of `STREQUAL`,
`MATCHES` and `IN_LIST` where I was confident it was unintended.
Fixes#65028.
This requests performs an index store index of the given file using the
given index store path and index unit output path. All other options are
derived from the index store related compiler flags.
This will allow IDEs like Xcode to index the file directly inside of
sourcekitd and potentially reuse an already built AST.
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.
