To construct struct syntax, this patch first specialized type
inheritance clause. For protocol's class requirement, we currently
treat it as an unknown type.
This patch also teaches SyntaxParsingContext to collect syntax nodes
from back in place. This is useful to squash multiple decl modifiers
for declarations like function. This is not used for struct declaration
because only accessibility modifier is allowed.
Previous versions of Swift accidentally treated lazy properties as
computed properties because of how they were implemented. Now that we
check this correctly, we've broken source compatibility. Downgrade the
error to a warning in this case.
(Arguably we could /allow/ overriding with a stored property. The
original concerns were that you could accidentally end up with extra
storage you didn't need, and that observing accessors would behave
differently based on whether or not the property was overriding. But
there's at least no ambiguity for 'lazy', which can't have observing
accessors today.)

This works a around search path problems caused by a module existing
in both the build/install directory and the source directory.

This patch also performs minor refactoring to align syntax parsing
context with the right scope. We start to support the generic clauses
because they are necessary pieces to construct struct or
function syntax node.
- Outlaw duplicate input files, fix driver, fix tests, and add test.
- Reflect that no buffer is present without a (possibly pseudo) named file.
- Reflect fact that every input has a (possible pseudo) name.
- Break up CompilerInstance::setup.
Don't bail on dups.
Proper evaluation of conditional conformances at runtime (e.g., as part of
dynamic casting) is too large to tackle in the Swift 4.1 timeframe. For now,
record that a conformance is conditional in the protocol conformance record,
and always return "does not conform" to such types.
Fixes rdar://problem/35761301.
Instead, just emit a deprecation warning and suggest switching to Optionals.
The old behavior caused several projects to break, so before we change
the behavior here we need to investigate whether we can mitigate most
of those breaks.
Because generic where clause doesn't coerce well to our existing syntax
context kinds, we add a new syntax context kind with this patch called
"Syntax". This context kind indicates that when error occurs, the
collection of syntax nodes falling into the context should be coerced
to UnknownSyntax.
- Moved getOutputFilenamesFromCommandLineOrFilelist & readOutputFileLIst to better places in the file.
- Capitalization changes.
- Make actionIsImmediate static.
- Add braces around sections of CompilerInstance::setup to clarify scopes of local variables.
We can just !SILFunction::hasQualifiedOwnership(). Plus as Andy pointed out,
even ignoring the functional aspects, having APIs with names this close can
create confusion.
The empty sentinel in the lookup table caused recursion-breaking to bottom
out in slightly different order than the old eager code, making certain
order-sensitive tests fail.
Unify actionHasOutput w/ doesActionProduceOutput & correct both.
Do not set an output filename if there is no output.
Add test to ensure no output is created in immediate mode.
Restore NFC module name computation.
1) TypeKind only needs six bits at the moment, so this leaves us with
plenty of room for additional type kinds.
2) While the size of TypeBase does not change, there are many more bits
available for subtypes to use.
