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.
It is possible for the SIL optimizers, IRGen, etc. to request information
from the AST that only the type checker can provide, but the type checker
is typically torn down after the “type checking” phase. This can lead to
various crashes late in the compilation cycle.
Keep the type checker instance around as long as the ASTContext is alive
or until someone asks for it to be destroyed.
Fixes SR-285 / rdar://problem/23677338.
Rather than limiting this to protocols, allow any nominal type.
Rename -enable-operator-designated-protocols to
-enable-operator-designated-types to reflect the change.
The YAML format is the same one produced by the -dump-type-info
frontend mode.
For now this is only enabled if the -read-type-info-path frontend
flag is specified.
Progress on <rdar://problem/17528739>.
Commit to a command line option spelling so that build systems can
start testing it. I deliberately picked one of the longer names we
were considering because we can always decide to add a shorter alias,
but can't decide a shorter name was too generic.
Like the other supplementary output flags,
-emit-parseable-module-interface-path will emit a .swiftinterface file
to a particular path, while -emit-parseable-module-interface will put
it next to the main output (the one specified with -o).

We already have something called "module interfaces" -- it's the
generated interface view that you can see in Xcode, the interface
that's meant for developers using a library. Of course, that's also a
textual format. To reduce confusion, rename the new module stability
feature to "parseable [module] interfaces".
Textual module interfaces don't actually depend on SILGen, so we
shouldn't need to run SILGen (or serialize an entire binary module) if
we're just trying to emit a textual interface. On the other hand, if
we /are/ going to run SILGen and then SIL diagnostics, we shouldn't
delay those diagnostics by spending time emitting a textual interface,
or for that matter a TBD file.
Using this, update all the ModuleInterface tests that use
`-emit-module -o /dev/null` to use `-typecheck` instead, except for
those using `-merge-modules`.
Add a staging option for enabling upcoming changes in the solver in
support of using the protocols designated in Policy.swift to guide
operator type checking.
The previous statement happened to work out of sheer luck. `MainModule` is
initialized by the call to `getMainModule()`. The expression could be evaluated
in any order, and in the Visual Studio case, was evaluated with the index
*first*. At this point `MainModule` was uninitialized (fortunately, it was set
to NULL). As a result, the `getName` call would fail. Ensure that the
`MainModule` is initialized first by using a local variable.
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.
The use of `std::move` forces the complete definition of the `SILModule` type.
Move the definition out-of-line to allow a forward declaration of `SILModule`
instead.
