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`.
swift-evolve hasn’t been used in the recent past. @beccadax and I agreed that it doesn’t provide any value anymore to keep swift-evolve around. In Becca’s words:
> The resilience implementation is pretty stable at this point, and it never seems to have had many of the bugs that swift-evolve would have been able to shake out.
This patch adds a new build products to build and test the Swift stdlib
for WebAssembly.
This adds WebAssembly specific stdlib product instead of adding the new
target in `stdlib-deployment-targets` because unlike darwin platforms
Wasm target has quite different stdlib configuration from host target
and there is no way to specify different stdlib configuration for each
target in `stdlib-deployment-targets` for now.
This patch adds 1 new dependency `wasi-libc` and 3 new build products:
1. `WASILibc` - wasi-libc is a libc implementation for WebAssembly
System Interface (WASI). This product is required to build the
compiler runtimes and Swift stdlib.
2. `WasmLLVMRuntimeLibs` - This product builds `./runtimes` directory
in llvm-project, which contains compiler-rt, libcxx and libcxxabi.
This product is required to build Swift stdlib.
3. `WasmStdlib` - This product builds standalone Swift stdlib for
WebAssembly. (Similar to `MinimalStdlib` product, but configured for
WebAssembly target)
This library served its purpose and has overstayed its welcome.
The library shipped in Xcode can't change again from the state it was
in, so changes to the sources here will not affect that library, which
is confusing. The library does not currently build due to changes in the
runtime headers, so it does not give meaningful signal to anything
anymore. If you need to test things in a backdeploy concurrency
environment, use the copy from the toolchain in Xcode as that will give
you a far clearer picture of what the code will actually be running with
than the state of the sources here did.
Treat the C++ interop modules similar to the Concurrency and
StringProcessing modules, enabled through a top-level global flag. The
flag now enables disabling the C++ interop modules when the standard
library is built.
Based on the original work by Egor Zhdan!
I'd inserted an extra line, which upset the line numbers in the backtracing
tests.
Also tweak the Python build script tests slightly so they work.

This is the start of the removal of the C++ implementation of libSyntax
in favor of the new Swift Parser and Swift Syntax libraries. Now that
the Swift Parser has switched the SwiftSyntaxParser library over to
being a thin wrapper around the Swift Parser, there is no longer any
reason we need to retain any libSyntax infrastructure in the swift
compiler.
As a first step, delete the infrastructure that builds
lib_InternalSwiftSyntaxParser and convert any scripts that mention
it to instead mention the static mirror libraries. The --swiftsyntax
build-script flag has been retained and will now just execute the
SwiftSyntax and Swift Parser builds with the just-built tools.
Similar to the way the early Swift Driver is built, introduce a
build-script option `--early-swiftsyntax` that uses the host Swift and
CMake to build the parts of the swift-syntax package that are expected
to become be used in the compiler.
Note that this does not obviate the need for the `--swiftsyntax`
option, because that build product uses the just-built Swift compiler
and SwiftPM to build, test, and install everything from the
swift-syntax package.
The `__future__` we relied on is now, where the 3 specific things are
all included [since Python 3.0](https://docs.python.org/3/library/__future__.html):
* absolute_import
* print_function
* unicode_literals
* division
These import statements are no-ops and are no longer necessary.
This patch adds a zlib and static-zlib build product, respectively
producing a dynamic and static zlib library. This is a dependency of
building Foundation.
Internal configurations targeting Darwin employ ThinLTO to
improve compiler performance, however using it on all executable
causes build time to increase with no matching benefit.
To reduce build times in such configurations, we allow some
ancillary targets to opt out of LLVM IR optimizations when linking
ThinLTO with ld64 (e.g. tools used for bootstrapping or debugging the
Swift compiler) -- this behaviour is opt in through a new flag
`--swift-tools-ld64-lto-codegen-only-for-supporting-targets`.
