This reverts commit efaf1fbefa.
Add a much more palatable workaround for the unit tests. Rather than
adding the dllimport for the symbols, locally define the required
symbols. This list is sufficient to restore the ability to build tests
for Windows.
Always use mangled type names to represent type metadata in keypath patterns.
For generic types, use the generic environment to pull substituted types
from the instantiation arguments.
Finishes the type metadata part of rdar://problem/38038799.
Provide additional stubs for known metadata. These are used in the unit
tests which do not link against the standard library and thus do not
have the known metadata. Augment the existing metadata stubs with the
new decorated names and entries.
Describe the consequences of missing metadata instead of just posting a scary
message about a bug. Furthermore, since these warnings tend to show up in
playgrounds, and probably aren't relevant to the user of a playground, suppress
them when running in a playground. rdar://problem/44642942
Since the mangling scheme and set of standard library types is effectively
fixed now, introduce known mangling substitutions for a number of new
standard library types, filling out the S[A-Za-z] space.
Reduces standard library binary size by ~195k.
When building swift on macOS with long tests, the build would fail with
undefined references to these symbols. The undefined symbols were
expected to be present in swiftCore against which we link. However,
because the symbols are marked as internal, they would be dead stripped
before the dylib was constructed. As a result, we would end up with
undefined references to these symbols. Expose the additional internal
interfaces for now so that we can build the tests.
* [runtime] Clean up symbols in error machinery.
* [runtime] Clean up symbols in Foundation overlay.
* [runtime] Clean up symbols in collections and hashing.
* [runtime] Remove symbol controls from the Linux definition of swift_allocError.
* [tests] Add more stub functions for tests that link directly to the runtime.
If the Swift error wrapped in a _SwiftNativeNSError box conforms to
Hashable, the box now uses the Swift's conformance to Hashable.
