Clang importer is unable to handle `((void *)-1)`, therefore manually
declaring the said constant in both Darwin and Glibc modules.
rdar://problem/26689135
Things like: PthreadBarriers.swift:114:50: error: cannot convert value of type 'UnsafeMutablePointer<pthread_mutex_t>' (aka 'UnsafeMutablePointer<OpaquePointer>') to expected argument type 'UnsafeMutablePointer<pthread_mutex_t?>' (aka 'UnsafeMutablePointer<Optional<OpaquePointer>>')
on barrier.pointee.mutex . I need to do more research to understand this
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.
