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.
Build swift-frontend as the primary Swift binary, and have
swift/swiftc/etc. symlink over to it. This is a step toward allowing
swift-driver to replace the swift and swiftc binaries.
Whoever touched this test last didn't know the rule for arguments
passed to the interpreter: if they're after the file to interpret,
they're treated as arguments to the script rather than the compiler.
Several of the swift repl tests assume that lldb does not exist next to the swift driver in the binary directory. This patch updates the tests to remove that assumption. This allows the swift tests to correctly pass if LLDB is built in-tree.
These tests are all checking for invocations of the legacy swift repl. If LLDB is in the directory next to swift they fail because it instead invokes the LLDB repl. This patch makes the tests pass by hard linking the swift driver into a temp directory before running those tests so that swift doesn't find LLDB sitting next to itself.
- This allows 'swift <FOO>' to be used to invoke swift-<FOO>, so that we can
use 'swift' as a namespace for additional commands (like ones used for the
package manager.
- This patch just adds the basic subcommand functionality, but doesn't rework
either 'swift-autolink-extract' or 'swift -frontend' to follow this code path.
- <rdar://problem/22844530> Provide 'swift' support for subcommands
