The definition may be tagged with `extern`, however, this does nothing. In the
header, it may be used to indicate to other TUs that the definition is external
to the TU. Remove the unnecessary modifier. NFC.
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.
As proposed in SE-0107: UnsafeRawPointer.
`void*` imports as `UnsafeMutableRawPointer`.
`const void*` imports as `UnsafeRawPointer`.
Occurrences of `UnsafePointer<Void>` are replaced with UnsafeRawPointer.
* Migrate overlays from UnsafePointer<Void> to UnsafeRawPointer.
This requires explicit memory binding in several places,
particularly in NSData and CoreAudio.
* Fix a bunch of test cases for Void->Raw migration.
* qsort takes IUO values
* Bridge `Unsafe[Mutable]RawPointer as `void [const] *`.
* Parse #dsohandle as UnsafeMutableRawPointer
* Update a bunch of test cases for Void->Raw migration.
* Trivial fix for the SceneKit test case.
* Add an UnsafeRawPointer self initializer.
This is unfortunately necessary for assignment between types imported from C.
* Tiny simplification of the initializer.
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.

This removes conformance of DarwinBool and ObjCBool to the Boolean protocol,
and makes the &&/||/! operators be concrete w.r.t. Bool instead of abstract
on Boolean.
This fixes some outstanding bugs w.r.t diagnostics, but exposes some cases
where an existing diagnostic is not great. I'll fix that in a later patch
(tracked by rdar://27391581).
errno is implemented as a macro in many environments. The accessor hidden
behind the macro is not a standard function, so we ended up with an
implementation specific handling across all the targets. Shim the function in C
where it can be hidden behind the CPP. This simplifies the implementation on
the swift side.
Replace the non-generic tgmath functions with generic <T: FloatingPoint> implementations where possible, and move the global sqrt() operation into tgmath.
This adds the swiftMSVCRT module which is similar in spirit to swiftGlibc and
swiftDarwin, exposing the Microsoft C Runtime library to swift. Furthermore,
disable pieces of the standard library which are not immediately trivially
portable to Windows. A lot of this functionality can still be implemented and
exposed to the user, however, this is the quickest means to a PoC for native
windows support.
As a temporary solution, add a -DCYGWIN flag to indicate that we are building
for the cygwin windows target. This allows us to continue supporting the cygwin
environment whilst making the windows port work natively against the windows
environment (msvc). Eventually, that will hopefully be replaced with an
environment check in swift.
change includes both the necessary protocol updates and the deprecation
warnings
suitable for migration. A future patch will remove the renamings and
make this
a hard error.
Always construct the platform libraries for all the target SDKs. This enables
us to build the right set for targets and will also enable us to cross-compile
multiple targets simultaneously.
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
There are a couple of features that are not yet implemented, because they require additions to the Builtin module. Specifically, this implementation does not have:
- formRemainder(dividingBy:)
- formSquareRoot()
- addProduct(_:,_:)
Also missing are the generic initializers and comparisons whose implementation depends on having new Integer protocols.
The last remaining feature of SE-0067 is that while the basic operators +,-,*,/, etc are moved onto the FloatingPoint protocol, they are still required on the concrete types in order to disambiguate overloads. Fixing this seems to require either modifying the overload resolution rules or removing these operators from some other protocols. Or it might just require that someone smarter than me looks at the problem.
Passes all the existing tests (with the included changes). I'm working on additional tests for the new features.
The general rule here is that something needs to be SWIFT_CC(swift)
if it's just declared in Swift code using _silgen_name, as opposed to
importing something via a header.
Of course, SWIFT_CC(swift) expands to nothing by default for now, and
I haven't made an effort yet to add the indirect-result / context
parameter ABI attributes. This is just a best-effort first pass.
I also took the opportunity to shift a few files to just implement
their shims header and to demote a few things to be private stdlib
interfaces.
This adds an Android target for the stdlib. It is also the first
example of cross-compiling outside of Darwin.

The Android variant of Swift may be built using the following `build-script`
invocation:
```
$ utils/build-script \
-R \ # Build in ReleaseAssert mode.
--android \ # Build for Android.
--android-ndk ~/android-ndk-r10e \ # Path to an Android NDK.
--android-ndk-version 21 \
--android-icu-uc ~/libicu-android/armeabi-v7a/libicuuc.so \
--android-icu-uc-include ~/libicu-android/armeabi-v7a/icu/source/common \
--android-icu-i18n ~/libicu-android/armeabi-v7a/libicui18n.so \
--android-icu-i18n-include ~/libicu-android/armeabi-v7a/icu/source/i18n/
```
Android builds have the following dependencies, as can be seen in
the build script invocation:
1. An Android NDK of version 21 or greater, available to download
here: http://developer.android.com/ndk/downloads/index.html.
2. A libicu compatible with android-armv7.
Implements SE-0055: https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md
- Add NULL as an extra inhabitant of Builtin.RawPointer (currently
hardcoded to 0 rather than being target-dependent).
- Import non-object pointers as Optional/IUO when nullable/null_unspecified
(like everything else).
- Change the type checker's *-to-pointer conversions to handle a layer of
optional.
- Use 'AutoreleasingUnsafeMutablePointer<NSError?>?' as the type of error
parameters exported to Objective-C.
- Drop NilLiteralConvertible conformance for all pointer types.
- Update the standard library and then all the tests.
I've decided to leave this commit only updating existing tests; any new
tests will come in the following commits. (That may mean some additional
implementation work to follow.)
The other major piece that's missing here is migration. I'm hoping we get
a lot of that with Swift 1.1's work for optional object references, but
I still need to investigate.
A great deal of duplication exists across the Linux and FreeBSD
modulemaps. An Android modulemap would add even more duplication.
Use gyb to conditionally include certain exports for certain
platforms. Most of glibc.modulemap is common across Linux and FreeBSD,
and using gyb we can conditionally include the two exports that differ.
- Add newlines where missing to match sys/errno.h error groups separation
- Prefer single-line comments to C-style comments
- Align most comments to same column
- Add comment following #endif at EOF to show what it ends
- Remove extraneous whitespace
This is a staging attribute that will eventually mean "fixed-contents"
for structs and "closed" for enums, as described in
docs/LibraryEvolution.rst.
This is pretty much the minimal set of types that must be fixed-layout,
because SILGen makes assumptions about their lowering.
If desired, some SILGen refactoring can allow some of these to be
resilient. For example, bridging value types could be made to work
with resilient types.
