Due to the fact that we do not statically link the toolchain, we cannot
currently support this test. Mark it as unavailable currently with the
early syntax parser enabled.
Ensure that we link `swift_CompilerPluginSupport` into the compiler and
SourceKit, and set the rpath appropriately to find the library in its
installed location.
A number of driver tests copy the driver executable into a temporary
directory to isolate it from the build tree. Also copy the plugin
support library into its appropriate place near the driver executable
to ensure these tests keep working. To help with this, add a
`swift_swift_parser` lit feature, which we can use in tests that
involve the new parser's capabilities.
Adding build modes for libswift: off, hosttools, bootstrapping, bootstrapping-with-hostlibs
The two bootstrapping modes are new. For details see libswift/README.md
Hardlinking to a symlink is not permitted, so use "swift-frontend"
instead of "swift" as the hard-link target.
Also, update one Linux-specific test to check for swift-frontend.
Use `clang` rather than `clang++` as the linker driver. This ensures
that we do not force a C++ runtime on the general code. This is fine
for now as C++ interop is not yet available for Swift. This prevents
the accidental mix-and-match of various C++ runtimes. This can cause
problems on platforms like android where `libstdc++` is an unsupported
runtime but is generally the default for Linux platforms.
Rather than aborting due to an assertion failure, emit a diagnostic.
This is much safer and generally easier to understand why the command
failed. It solves the problem of running swiftc from the build without
the path being set such that the clang++ driver is found by the swift
driver.
