Fix readMetadataBoundsOfSuperclass to recursively apply adjustForSubclass while going through the superclass chain.
Strip indirect descriptor pointers so we can deal with signed pointers here.
Make CMemoryReader assert (in asserts builds) that the addresses being read don't have any signature bits set, which helps track down places where we need to add stripping.

As of the changes in https://github.com/swiftlang/swift/pull/41713 to
enable Sendability for AsyncStream, it has been possible to create
multiple stream consumers operating concurrently. This change fixes
behavior in the case that the underlying stream is terminated while
multiple pending continuations are outstanding. Previously such
consumers would have been leaked (never resumed). Now, they are notified
of the stream's termination and resumed appropriately.
Resolves#66541 & #71412
Annotate all of the `Unsafe*` types and `unsafe` functions in the standard
library (including concurrency, synchronization, etc.) as `@unsafe`. Add a
few tests to ensure that we detect uses of these types in clients that
have disabled unsafe code.
macOS 15.0, iOS 18.0, et al has started unconditionally declaring `lgamma_r` in <math.h>, add a __has_include in SwiftShims to detect that and not redeclare it when building against those SDK versions.

This patch adds an apinotes file for SwiftWASILibc clang module to mark
`errno` macro hidden from Swift code. This resolves ambiguity between
the C macro definition and the Swift wrapper in WASILibc overlay module.
This change installs the apinotes file to the resource directories for
both lib/swift/apinotes and lib/swift_static/apinotes.
add_swift_target_library was missing pieces for passing sources and
flags to the static SDK build. As a result, the static SDK was missing
pieces (specifically Mutex).
Also adding the Musl import to the Linux Mutex implementation.
This commit fixes an ambiguous `errno` error when importing WASILibc
module and SwiftWASILibc Clang module.
The error is caused by the fact that we define a shim for `errno` in
`Platform.swift` file, but wasi-libc defines `errno` in a way
ClangImporter can understand. We don't need to define shims for it,
otherwise we get two candidates for `errno` identifier.
We need to make sure that we build swift-backtrace with a deployment target
newer than 10.14.4 in order that we get linked against
`/usr/lib/swift/libswiftCore.dylib` rather than using an `@rpath`-based
path.
If we fail to do that, dyld becomes confused and we end up crashing with
weird errors about missing method implementations on `Swift.__StringStorage`.
To make this work, add support for `DEPLOYMENT_VERSION_*` in the
`add_swift_target_executable()` CMake function. And since I spotted a bug
in it, fix the existing support in `add_swift_target_library()` while I'm
there.
