build: improve swift build/integration Add explicit links against the swift runtime for the tests which may use the swift runtime. This prevents link failures for the swift tests. Install the swiftmodule and swiftdoc into the installed image. Correct the modulemap installation. Fix a typo in the header installation.
Grand Central Dispatch (GCD or libdispatch) provides comprehensive support for concurrent code execution on multicore hardware.
libdispatch is currently available on all Darwin platforms. This project aims to make a modern version of libdispatch available on all other Swift platforms. To do this, we will implement as much of the portable subset of the API as possible, using the existing open source C implementation.
libdispatch on Darwin is a combination of logic in the xnu
kernel alongside the user-space Library. The kernel has the most information available to balance workload across the entire system. As a first step, however, we believe it is useful to bring up the basic functionality of the library using user-space pthread primitives on Linux. Eventually, a Linux kernel module could be developed to support more informed thread scheduling.
A port of libdispatch to Linux has been completed. On Linux, since Swift 3, swift-corelibs-libdispatch has been included in all Swift releases and is used by other swift-corelibs projects.
Opportunities to contribute and on-going work include:
