We have a regression test checked in the compiler repository to detect ABI breakges as the
stdlib evolves, therefore we don't need to generate these side car files for ABI checking
purposes that could be potentially done externally.

This allows us to build swift-format with dynamic linking against the
toolchain build of the swift-syntax and swift-argument-parser packages.
Wire up the swift-markdown build and hoist the swift-format build prior
to sourcekit-lsp. This sets us up for supporting swift-format based
formatting in the LSP.
This patch introduces `--enable-experimental-noncopyable-generics` for
the build script. It replaces
`--swift-stdlib-experimental-noncopyable-generics`
The old build option only enables the feature when building the
stdlib, but if we've built the stdlib with NoncopyableGenerics, the
compiler should be hardwired to have that feature enabled, too.
This patch also introduces the `noncopyable_generics` lit parameter, so
that tests assuming the system was built with the feature can live
in-tree and be tested, if they specify `REQUIRES: noncopyable_generics`.
Obsolete the `-enable-swift3-objc-inference` option and related options by
removing support for inferring `@objc` attributes using Swift 3 rules.
Automated migration from Swift 3 has not been supported by the compiler for
many years.
This is a temporary measure until I get a chance to fix the symbol
mangling. This round-tripper is exactly flagging the current
known issue in that all of the symbols get extra `Copyable` and
`Escapable` requirements mangled into them, and thus reconsituting the
type from the mangled name doesn't give you the same type back.
which executor for which type of setting, is consolidated and we have a
single knob we use to determine when to use dispatch as our global
executor.

Add a `SWIFT_STDLIB_OVERRIDABLE_RETAIN_RELEASE` CMake option. When set to true, swift_retain/release and the other functions in InstrumentsSupport.h can be overridden by setting the appropriate global function pointer, as is already the case. When set to false, those function pointers are removed and the functions always go into the default implementation.
Set `SWIFT_STDLIB_OVERRIDABLE_RETAIN_RELEASE` to false when building the minimal stdlib, and set it to true otherwise by default.

The CMake flag `DEPLOYMENT_VERSION_OSX` is currently only passed to the C compiler. This change makes sure it is also passed to the Swift compiler, e.g. when building Swift-only targets like Cxx or CxxStdlib.

This would be needed to stop using `swift-api-extract` in some
internal configurations.
Given the limited scope, only add this as a CMake flag.

This isn't a "complete" port of the standard library for embedded Swift, but
something that should serve as a starting point for further iterations on the
stdlib.
- General CMake logic for building a library as ".swiftmodule only" (ONLY_SWIFTMODULE).
- CMake logic in stdlib/public/core/CMakeLists.txt to start building the embedded stdlib for a handful of hardcoded target triples.
- Lots of annotations throughout the standard library to make types, functions, protocols unavailable in embedded Swift (@_unavailableInEmbedded).
- Mainly this is about stdlib functionality that relies on existentials, type erasure, metatypes, reflection, string interpolations.
- We rely on function body removal of unavailable functions to eliminate the actual problematic SIL code (existentials).
- Many .swift files are not included in the compilation of embedded stdlib at all, to simplify the scope of the annotations.
- EmbeddedStubs.swift is used to stub out (as unavailable and fatalError'd) the missing functionality.
Use 'copy_if_different' instead of 'file(GENERATE'. Somehow
'file(GENERATE' failed with
CMake Error: Files to be generated by multiple different commands:
Write source file list using 'file(GENERATE' so that they are updated
only if thier content is changed. Otherwise stdlib modules are rebuild
everytime cmake configuration happens.
'.private.swiftinterface' should be a part of the module. And it's
declared as `OUTPUT` file list, but they were never created. Because of
that the target was always rebuilt.
Ubuntu 18.04 seems to be defaulting to 'ascii', causing an error when
using line-directive combined with the utf-8 diagnostic output used when
early swift syntax is enabled.
Some non-stdlib thing e.g. swift-backtrace still might be built before
the runtime is built. For building Swift code in Linux "hosttools",
always set 'LD_LIBRARY_PATH' to the runtime in the builder.
The CxxStdlib module is built statically only. We would previously
build the static library but indicate dynamic linking. This would
incorrectly code generate in the client on Windows making it impossible
to use the module.
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.
We have various pieces of SPI that are getting used in tests that are
failing occasionally. The swiftmodule file has the SPI, so if the
compiler loads from the swiftmodule file, everything works fine. If the
compiler loads the interface from the swiftinterface file, it fails to
find the `startOnMainActor` declaration.
