On OpenBSD, x86_64 is spelled as amd64, and Swift already uses amd64 for the module path on this platform. We save the target architecture name as `target_arch` elsewhere in the lit config file, so on this platform, we need to use this for the module path.
* Not implementing POSIXError for a given platform is not a blocking problem to getting a successful build of Swift. However, it is part of the validation tests (albeit locked behind REQUIRES) and is referenced when building Foundation. Implement by forklifting from `sys/errno.h`. * Some Foundation class implementations require some missing includes in the platform modulemap. Add these.
Also see swiftlang#38140; we can remove this XFAIL just like Linux.

…ded. Mostly this consists of #if-ing out code that we don't need when running single threaded. rdar://84393438
Rather than conditionalising all the calls to mutex.lock() and mutex.unlock(), centralise the logic. rdar://84393438
This allows me to selectively enable build features (such as building lldb, building swiftpm reconfiguring etc.) locally from a single preset.
Fixes <rdar://82053644>. (cherry picked from commit e48de1a)
Let the later changes in stdlib/public/Concurrency/Task.swift win, since they contain and supersede this minor fix anyhow, instead of creating a merge conflict with 'main'. This reverts commit 1d63a5d.
Kuba reckons this will fix the test hanging. rdar://84393438
…c metadata This extends swiftlang#39944 to apply to more objc metadata. rdar://85037490
…lying this to PROTOCOL related data rdar://86256970
The cases' new names more accurately reflect what behavior occurs when SILOptions::LexicalLifetimes is assigned that case.
If -disable-copy-propagation is passed, just emit lexical diagnostic markers but do not enable lexical lifetimes.
when a task is adding adding new children to a task group, we need to synchronize with the task status record lock of the parent task that has the task group, to prevent races with concurrent cancellation and escalation. Radar-Id: rdar://problem/86311782
…an initial value.
We process these as loadable vars. This is really useful since it ensures that
uniqueness is preserved in this case:
```
let x: K2
do {
x = self.k2
}
switch _move(x)[userHandle] {
case .foo:
assert(_isUnique(&self.k2))
}
```
I added a test that proves this.
…td::copy() to avoid calling destructors on uninitialized memory
1) Don't force ObjC interop just to enable gratuitous `@objc deinit`. 2) Prefer `-enable-objc-interop` over `REQUIRES: objc_interop`.
