Most clients were only using it to populate the
main module with files, which is now done by
`getMainModule`. Instead, they can now just rely
on parsing happening lazily.
Lift the `DisablePoundIfEvaluation` parsing option
into `LangOptions` to subsume the need for the
`EvaluateConditionals` parameter, and sink the
computation of `CanDelayBodies` down into
`createSourceFileForMainModule`.
Single-expression closures have always been traversed differently
from multi-statement closures. The former were traversed as if the
expression was their only child, skipping the BraceStmt and implicit
return, while the later was traversed as a normal BraceStmt.
Unify on the latter treatment, so that traversal
There are a few places where we unintentionally relied on this
expression-as-child behavior. Clean those up to work with arbitrary
closures, which is an overall simplification in the logic.
This change makes us treat it exactly as we do 'init'. We don't allow renaming the base name,
and don't fail if the basename doesn't match for calls.
Also:
- explicit init calls/references like `MyType.init(42)` are now reported with
'init' as a keywordBase range, rather than nothing.
- cursor info no longer reports rename as available on init/callAsFunction
calls without arguments, as there's nothing to rename in that case.
- Improved detection of when a referenced function is a call (rather than
reference) across syntactic rename, cursor-info, and indexing.
Resolves rdar://problem/60340429
Like switch cases, a catch clause may now include a comma-
separated list of patterns. The body will be executed if any
one of those patterns is matched.
This patch replaces `CatchStmt` with `CaseStmt` as the children
of `DoCatchStmt` in the AST. This necessitates a number of changes
throughout the compiler, including:
- Parser & libsyntax support for the new syntax and AST structure
- Typechecking of multi-pattern catches, including those which
contain bindings.
- SILGen support
- Code completion updates
- Profiler updates
- Name lookup changes
There were changes due to the StringRef to std::string conversion, changes
in the Debug Info DIBuilder::createModule API, and a drop in the using for
PointerUnion4 since PointerUnion is now a variadic template and will do in its
place.
Switch most callers to explicit indices. The exceptions lie in things that needs to manipulate the parsed output directly including the Parser and components of the ASTScope. These are included as friend class exceptions.
Note that in all cases it was either nullptr or ctx.getLazyResolver().
While passing in nullptr might appear at first glance to mean something
("don't type check anything"), in practice we would check for a nullptr
value and pull out ctx.getLazyResolver() instead. Furthermore, with
the lazy resolver going away (at least for resolveDeclSignature() calls),
it won't make sense to do that anymore anyway.
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances in the swift repo.
- Struct declarations are now eligible for the refactoring action
- Default argument expressions specified in source are printed into the generated initializer as well
Note that we are explicitly missing the ability to print a 'nil' default argument for members of type T? because TypeReprs are not fully resolved by the time the refactoring engine runs.
This has been an unnecessary code path for a long time now and should be removed particularly because it triggers wasteful `stat` calls.
