This patch causes the convenient flow to automatically populate the
sources into the new runtime directory layout. This is run at build-time
so that it repopulates on each build. Since the resync script uses
`COPY_IF_DIFFERENT`, only files that change in the main source directory
are copied over, so incremental builds should still work.
Fixed a small bug in the resync script to ensure that it creates the
subdirectories in the right places.
Fixing some of the comments in DefaultSettings.cmake and
PlatformInfo.cmake.
I haven't added any vendor cache files yet, so the comment doesn't point
anywhere. Also fixing the reference to the location of the clang
resource headers in PlatformInfo.cmake.
Moving the rest of the references to the compiler source directory to
use the `SwiftCore_SWIFTC_SOURCE_DIR` variable instead of
`${PROJECT_SOURCE_DIR}/../../`.
This patch makes it simpler to setup reasonable defaults for a given
platform. The standard library has many knobs for configuration
purposes. This is great for providing cache files to configure specific
builds, but the build system should still generally work if someone runs
a minimal CMake invocation against the build without futzing with
various options.
This patch hooks up the swiftCore library build and gets it installing.
This means that we have library evolution hooked up and vector types.
Building it dynamically found that we had duplicate symbols, so fixed
the swiftDemanglingCR library.
Needed to hook up the availability macros.
The flag configuration is for macOS, so we'll need to go through and
figure out what it should look like for the other platforms too.
Adding stdlib stubs library, which uses gyb and requires knowing about
some of the platform info.
The stubs library pulls in several headers from the compiler repository.
We should probably clean that up, but not right now. I've made a note of
it.
Adding a readme describing the different layers for the standard
libraries, and what libraries belong to which layer.
- Core: The core runtime libraries that provide basic operations
- Overlay: Maps the underlying system into Swift
- Supplemental: Libraries that use the underlying system
- Testing: Extraneous support for testing the standard libraries
