For compiling codes required for macro support, we now need swiftc
compiler in the build machine.
Unlike Darwin OSes, where swiftCore runtime is guaranteed to be present
in /usr/lib, Linux doesn't have ABI stability and the stdlib of the
build machine is not at the specific location. So the built compiler
cannot relies on the shared object in the toolchain.
The goal here is to make the short demangling as short and readable as possible, also at the cost of omitting some information.
The assumption is that whenever the short demangling is displayed, there is a way for the user to also get the full demangled name if needed.
*) omit <where ...> because it does not give useful information anyway
Deserializer.deserialize<A where ...> () throws -> [A]
--> Deserializer.deserialize<A> () throws -> [A]
*) for multiple specialized functions only emit a single “specialized”
specialized specialized Constructible.create(A.Element) -> Constructible<A>
--> specialized Constructible.create(A.Element) -> Constructible<A>
*) Don’t print function argument types:
foo(Int, Double, named: Int)
--> foo(_:_:named:)
This is a trade-off, because it can lead to ambiguity if there are overloads with different types.
*) make contexts of closures, local functions, etc. more readable by using “<a> in <b>” syntax
This is also done for the full and not only for the simplified demangling.
Renderer.(renderInlines([Inline]) -> String).(closure #1)
--> closure #1 in Renderer.renderInlines
*) change spacing, so that it matches our coding style:
foo <A> (x : A)
--> foo<A>(x: A)
LIT runs each unittest once to enumerate all tests. When the test
executable crashes during this run, no tests will be found and all
tests in that executable will be skipped. The SwiftDemangleTests
executable depends on a shared library. This patch changes the LIT
configuration to set the shared library path to the lib directory in
the build artifacts and thus re-enables the SwiftDemangleTests unit
test.
This library becomes a permanent interface that we would need to support
in the long term, so we should get dylib names and APIs right.
