8e5f79bd0a [gardening] Add "// REQUIRES: OS=linux-gnu" 
According to @swift-ci this crasher seems to be limited to Linux.
Feel free to remove this REQUIRES line if @swift-ci is wrong about
this :-)

4ed17f0f63 AST: Add a new 'isBeingValidated' flag to replace a couple of other flags 
Previously, validateDecl() would check if the declaration had an
interface type and use that as an indication not to proceed.

However for functions we can only set an interface type after
checking the generic signature, so a recursive call to validateDecl()
on a function would "steal" the outer call and complete validation.

For generic types, this meant we could have a declaration with a
valid interface type but no generic signature.

Both cases were problematic, so narrow workarounds were put in
place with additional new flags. This made the code harder to
reason about.

This patch consolidates the flags and establishes new invariants:

- If validateDecl() returns and the declaration has no interface
  type and the isBeingValidated() flag is not set, it means one
  of the parent contexts is being validated by an outer recursive
  call.

- If validateDecl() returns and the declaration has the
  isBeingValidated() flag set, it may or may not have an interface
  type. In this case, the declaration itself is being validated
  by an outer recursive call.

- If validateDecl() returns and the declaration has an interface
  type and the isBeingValidated() flag is not set, it means the
  declaration and all of its parent contexts are fully validated
  and ready for use.

In general, we still want name lookup to find things that have an
interface type but are not in a valid generic context, so for this
reason nominal types and associated types get an interface type as
early as possible.

Most other code only wants to see fully formed decls, so a new
hasValidSignature() method returns true iff the interface type is
set and the isBeingValidated() flag is not set.

For example, while resolving a type, we can resolve an unqualified
reference to a nominal type without a valid signature. However, when
applying generic parameters, the hasValidSignature() flag is used
to ensure we error out instead of crashing if the generic signature
has not yet been formed.

45ef0f5dfb Sema: Generic types cannot witness associated type requirements 
Until recently we didn't allow nested generic types at all.
In Swift 3, generic typealiases were added, and we forgot to
guard against them in witness matching, leading to a crash if
a generic typealias witnesses an associated type requirement.

Now that nested generic nominals are allowed too, add a check.

The diagnostic is not very good, but I'll revisit this later.

This catches another case where resolveType() could cause infinite
recursion. No test case, but this prevents crashers from regressing
with a subsequent patch.

38165e266c [QoI] Strip BindOptionalExpr from assignment that discards target 
Right before generating constraints for the new system,
check if there are any BindOptionalExpr in the tree which
wrap DiscardAssignmentExpr, such situation corresponds to syntax
like - `_? = <value>`, since it doesn't really make
sense to have optional assignment to discarded LValue which can
never be optional, we can remove BOE from the tree and avoid
generating any of the uncessary constraints.

66950c1349 [swiftc (109 vs. 5294)] Add crasher in swift::constraints::ConstraintSystem::getType(...) 
Add test case for crash triggered in `swift::constraints::ConstraintSystem::getType(...)`.

Current number of unresolved compiler crashers: 109 (5294 resolved)

/cc @rudkx - just wanted to let you know that this crasher caused an assertion failure for the assertion `ExprTypes[E]->isEqual(E->getType()) && "Expected type in map to be the same type in expression!"` added on 2016-12-11 by you in commit 1139f872 :-)

Assertion failure in [`lib/Sema/ConstraintSystem.h (line 1397)`](https://github.com/apple/swift/blob/master/lib/Sema/ConstraintSystem.h#L1397):

```
Assertion `ExprTypes[E]->isEqual(E->getType()) && "Expected type in map to be the same type in expression!"' failed.

When executing: swift::Type swift::constraints::ConstraintSystem::getType(swift::Expr *)
```

Assertion context:

```

  /// Get the type for an expression.
  Type getType(Expr *E) {
    assert(hasType(E) && "Expected type to have been set!");
    assert(ExprTypes[E]->isEqual(E->getType()) &&
           "Expected type in map to be the same type in expression!");
    return ExprTypes[E];
  }

  /// Cache the type of the expression argument and return that same
  /// argument.
```

88b54dcf51 AST: More consistent behavior of Type::subst() with missing substitutions 
When SubstFlags::UseErrorTypes was on, we would return error types
if we couldn't resolve a nested type, but a missing primary parameter
would always remain unsubstituted in the result.

Now, replace primary parameters with error types also if they're
missing.

Change the underlying type of TypeAliasDecls to an interface type
 2016-12-16 01:31:31 -08:00
Slava Pestov
2c6b9f71b6 AST: Change TypeAliasDecls to store an interface type as their underlying type 
- TypeAliasDecl::getAliasType() is gone. Now, getDeclaredInterfaceType()
  always returns the NameAliasType.

- NameAliasTypes now always desugar to the underlying type as an
  interface type.

- The NameAliasType of a generic type alias no longer desugars to an
  UnboundGenericType; call TypeAliasDecl::getUnboundGenericType() if you
  want that.

- The "lazy mapTypeOutOfContext()" hack for deserialized TypeAliasDecls
  is gone.

- The process of constructing a synthesized TypeAliasDecl is much simpler
  now; instead of calling computeType(), setInterfaceType() and then
  setting the recursive properties in the right order, just call
  setUnderlyingType(), passing it either an interface type or a
  contextual type.

  In particular, many places weren't setting the recursive properties,
  such as the ClangImporter and deserialization. This meant that queries
  such as hasArchetype() or hasTypeParameter() would return incorrect
  results on NameAliasTypes, which caused various subtle problems.

- Finally, add some more tests for generic typealiases, most of which
  fail because they're still pretty broken.

443bc682f6 Actually improve recovery when parsing bogus expressions 
The crashes fixed appeared at first to be related to IfConfigStmt
parsing, but are in reality symptoms of being too lax in what we accept
when parsing of sub-expressions fail.

Optional type annotation parsing used to propagate failures before it
was patched to ‘recover’ with an AnyPattern.  Instead, we’ll just hit
the error path for parsing in the main expressions because what is here
now isn’t a reasonable thing to return.

#selector parsing assumed that the current token it was at after
consuming up to a right-brace wasn’t bogus.  Instead, if we’ve got
here, we may as well just return a loc we know is valid: PreviousLoc.

Assertion failure in [`lib/Sema/ConstraintSystem.h (line 1395)`](https://github.com/apple/swift/blob/master/lib/Sema/ConstraintSystem.h#L1395):

```
Assertion `hasType(E) && "Expected type to have been set!"' failed.

When executing: swift::Type swift::constraints::ConstraintSystem::getType(swift::Expr *)
```

Assertion context:

```
    return ExprTypes.find(E) != ExprTypes.end();
  }

  /// Get the type for an expression.
  Type getType(Expr *E) {
    assert(hasType(E) && "Expected type to have been set!");
    assert(ExprTypes[E]->isEqual(E->getType()) &&
           "Expected type in map to be the same type in expression!");
    return ExprTypes[E];
  }

```

a52ad69c1e Sema: Avoid validateDecl() recursion through the 'unsupported existential' check 
When type-checking decls, we would ensure they don't reference
existential types formed from protocols with associated types
or 'Self' requirements. However this check was done in both
'stage 1' and 'stage 2', which meant it would be called
recursively from validateDecl().

Fix this by performing the check only once at the end of
type checking a source file.

caceaed404 [swiftc (102 vs. 5282)] Add crasher in swift::ValueDecl::setInterfaceType(...) 
Add test case for crash triggered in `swift::ValueDecl::setInterfaceType(...)`.

Current number of unresolved compiler crashers: 102 (5282 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!type->hasArchetype() && "Archetype in interface type"` added on 2016-12-03 by you in commit 1a991da1 :-)

Assertion failure in [`lib/AST/Decl.cpp (line 1667)`](https://github.com/apple/swift/blob/master/lib/AST/Decl.cpp#L1667):

```
Assertion `!type->hasArchetype() && "Archetype in interface type"' failed.

When executing: void swift::ValueDecl::setInterfaceType(swift::Type)
```

Assertion context:

```
  if (!type.isNull() &&
      !isa<TypeAliasDecl>(this) &&
      !(isa<ParamDecl>(this) &&
        isa<AbstractClosureExpr>(getDeclContext()))) {
    assert(!type->hasArchetype() &&
           "Archetype in interface type");
    assert(!type->hasTypeVariable() &&
           "Archetype in interface type");
