With the unqualified fallback we start to hit this assertion for
`return nil` in failable intializers. We ought to be able to just
skip over literal buckets though.
For hosts that have a swiftly-managed Swift compiler, we could not
bootstrap using those tools, because of some hardcoded assumptions
about where the `/lib` directory lives, relative to the `/bin`
directory that contains the detected `swiftc`.
This patch adds specific support for detecting when the `swiftc`
is coming from a swiftly install and uses the correct paths.
I've tested this patch on my Linux machine that has swiftly 1.0.1,
with the Swift 6.1.2 toolchain.
Add an extra opaque field to AddressSpace, which can be used by clients
of RemoteInspection to distinguish between different address spaces.
LLDB employs an optimization where it reads memory from files instead of
the running process whenever it can to speed up memory reads (these can
be slow when debugging something over a network). To do this, it needs
to keep track whether an address originated from a process or a file. It
currently distinguishes addresses by setting an unused high bit on the
address, but because of pointer authentication this is not a reliable
solution. In order to keep this optimization working, this patch adds an
extra opaque AddressSpace field to RemoteAddress, which LLDB can use on
its own implementation of MemoryReader to distinguish between addresses.
This patch is NFC for the other RemoteInspection clients, as it adds
extra information to RemoteAddress, which is entirely optional and if
unused should not change the behavior of the library.
Although this patch is quite big the changes are largely mechanical,
replacing threading StoredPointer with RemoteAddress.

The sourcekit in proc dynamic library looks up runtimes in a spot
relative to the Swift compiler. Set this location on freebsd, fixing the
sourcekit tests.
Currently, when we jump-to-definition for decls that are macro-expanded
from Clang imported decls (e.g., safe overloads generated by
@_SwiftifyImport), setLocationInfo() emits a bongus location pointing to
a generated buffer, leading the IDE to try to jump to a file that does
not exist.
The root cause here is that setLocationInfo() calls getOriginalRange()
(earlier, getOriginalLocation()), which was not written to account for
such cases where a macro is generated from another generated buffer
whose kind is 'AttributeFromClang'.
This patch fixes setLocationInfo() with some refactoring:
- getOriginalRange() is inlined into setLocationInfo(), so that the
generated buffer-handling logic is localized to that function. This
includes how it handles buffers generated for ReplacedFunctionBody.
- getOriginalLocation() is used in a couple of other places that only
care about macros expanded from the same buffer (so other generated
buffers not not relevant). This "macro-chasing" logic is simplified
and moved from ModuleDecl::getOriginalRange() to a free-standing
function, getMacroUnexpandedRange() (there is no reason for it to be
a method of ModuleDecl).
- GeneratedSourceInfo now carries an extra ClangNode field, which is
populated by getClangSwiftAttrSourceFile() when constructing
a generated buffer for an 'AttributeFromClang'. This could probably
be union'ed with one or more of the other fields in the future.

NFC *except* that I noticed a bug by inspection where we suppress
`@escaping` when print enum element types. Since this affects
recursive positions, we end up suppressing `@escaping` in places
we shouldn't. This is unlikely to affect much real code, but should
still obviously be fixed.
The new design is a little sketchy in that we're using `const` to
prevent direct use (and allow initialization of `const &` parameters)
but still relying on modification of the actual object. Essentially,
we are treating the `const`-ness of the reference as a promise to leave
the original value in the object after computation rather than a
guarantee of not modifying the object. This is okay --- a temporary
bound to a `const` reference is still a non-`const` object formally
and can be modified without invoking UB --- but makes me a little
uncomfortable.
Most `SemaAnnotator`s don’t actually care about the char source range. Instead, they only care about the start location of the reference, which is also included in `SourceRange`. Computing a `CharSourceRange` from a `SourceRange` is kind of expensive because it needs to start a new lexer.
To avoid this overhead, pass `SourceRange` to `SemaAnnotator::passReference` and related functions and let the clients compute the `CharSourceRange` when needed.
This reduces the overhead of index-while-building by about 10%.
Make `getOriginalLocation` work with source ranges, and adjust the
cursor info logic to map the range into the original buffer. This
fixes the case where we were using bogus range lengths for macro
expansion decls.

Introduce a new ASTWalker option for walking CustomAttrs and use it
for the placeholder scanner to ensure we can expand placeholders in
attribute arguments.
The diagnostic group documentation now point to the swift.org URL rather
than the toolchain path, so it no longer needs to be passed all the way
through sourcekitd.

We need this option for `collectVariableType` (aka inlay type hints) but since I’m at it, I’m adding an option to disable the implicit request cancellation for all requests that have it since we don’t want it in LSP at all.
Prerequisite to fixing https://github.com/swiftlang/sourcekit-lsp/issues/2021 / rdar://145871554, need to adopt this option in SourceKit-LSP.
In DarwinRemoteProcess's early return when libswiftCore.dylib isn't loaded in the process, we hadn't initialized all stored properties yet, which means our deinit didn't run. This leaked the task. This is especially bad when forking a corpse, as the system has a very limited number of corpses available.
Add a Cleanup helper to manage resources that need explicit cleanup. This is a noncopyable struct which takes a cleanup function and calls it whenever a new value is set or when the struct is destroyed. Use this for the DarwinRemoteProcess properties that need explicit cleanup. This allows us to remove DarwinRemoteProcess's deinit and always run these cleanups regardless of how we exit the initializer.
While we're here, fix the truncations of buffer in getAllProcesses.

If a module has the same `public-module-name` as the module being
generated and its import is exported, merge it into the same generated
interface.
Fix various always-imported modules from being printed while here and
update all the tests that checked for them.

It seems that a recent change to the compiler will now optimize the
initializer and then the SIL verifier will fail due to the unintialized
member when the initializer is throwing and will never return without
initializing the member unless the initialization fails.
We've been converging the implementations of educational notes and
diagnostic groups, where both provide category information in
diagnostics (e.g., `[#StrictMemorySafety]`) and corresponding
short-form documentation files. The diagnostic group model is more
useful in a few ways:
* It provides warnings-as-errors control for warnings in the group
* It is easier to associate a diagnostic with a group with
GROUPED_ERROR/GROUPED_WARNING than it is to have a separate diagnostic
ID -> mapping.
* It is easier to see our progress on diagnostic-group coverage
* It provides an easy name to use for diagnostic purposes.
Collapse the educational-notes infrastructure into diagnostic groups,
migrating all of the existing educational notes into new groups.
Simplify the code paths that dealt with multiple educational notes to
have a single, possibly-missing "category documentation URL", which is
how we're treating this.
