This adds two things:
- Calling `swiftc -dump-ast foo.swift [...] -o foo.ast` will dump the AST to the file `foo.ast`, instead of dumping it to `stderr` as usual.
- Calling `swiftc -dump-ast -output-file-map=outputFileMap.json *.swift [...]`, given an `outputFileMap.json` file that contains entries in the form `"ast-dump": "foo.ast"`, will dump the ASTs of the input files to their respective output files in the file map.
This should serve as a valid workaround to a bug mentioned in [the forums](https://forums.swift.org/t/error-when-dumping-the-ast-for-hundreds-of-files/17578) where the AST dump functionality crashes when called with too many input files. A few implementation details were also discussed in the same forum post.
As an aside, this also fixes a comment in `include/swift/Basic/PrimarySpecificPaths.h` that was incorrect.
This reverts commit 121f5b64be.
Sorry to revert this again. This commit makes some pretty big changes. After
messing with the merge-conflict created by this internally, I did not feel
comfortable landing this now. I talked with Saleem and he agreed with me that
this was the right thing to do.
The key thing here is that all of the underlying code is exactly the same. I
purposely did not debride anything. This is to ensure that I am not touching too
much and increasing the probability of weird errors from occurring. Thus the
exact same code should be executed... just the routing changed.
Also fix Edit::intersectsOrTouchesRange check only returning true when the
ranges overlapped, rather than when they overlapped or 'touched'.
Resolves rdar://problem/45108439
This was causing local refactorings (which are line+column-based) to fail due to
the provided location being considered invalid, even though the available
refactorings request (which uses offset directly) reported them as available.
This silences the instances of the warning from Visual Studio about not all
codepaths returning a value. This makes the output more readable and less
likely to lose useful warnings. NFC.
`env` is a default'ed parameter. In some cases it may be passed a `nullptr`,
which is not a valid parameter to `llvm::toStringRefArray`. Guard against this
case. This allows the swift compiler to work again on Windows!
* [InterfaceGen] Remove #ifs from default args
This patch removes all #if configs form the bodies of default arguments,
which can contain multiline closures, while preserving the bodies of the
clauses that are active.
This code is generalized and should "just work" for inlinable function
bodies, which will come in a later patch.
* Address review comments
* Fix and test CharSourceRange.overlaps
* Fix CharSourceRange::print to respect half-open ranges
