dd3869739e [GSB] Don't add invalid concrete requirements. 
When a concrete requirement is invalid due to the concrete type
lacking a conformance to a particular, required protocol, don't emit
that incorrect requirement---it causes invalid states further down the
line.

Fixes SR-5014 / rdar://problem/32402482.

While here, fix a comment that Huon noticed trailed off into oblivion.

c47aea7150 [GSB] Cope with typealiases within protocol hierarchies. 
When we see two type(aliase)s with the same name in a protocol
hierarchy, make them equal with an implied same-type requirement. This
detects inconstencies in typealiases across different protocols, and
eliminates the need for ad hoc consistency checking. This is a step
toward simplifying away the need for direct-diagnosis operations
involving concrete type mismatches.

While here, warn when we see an associated type with the same as a
typealias from an inherited protocol; in this case, the associated
type is basically useless, because it's going to be equivalent to the
typealias.

a72a2bf730 [GSB] Avoid recursively growing increasingly-nested potential archetypes. 
In some circumstances, we could end up growing increasingly-nested
potential archetypes due to a poor choice of representatives and
anchors. Address this in two places:

* Always prefer to use the potential archetype with a lower nesting
  depth (== number of nested types) to one with a greater nesting
  depth, so we don't accumulate more nested types onto the
  already-longer potential archetypes, and

* Prefer archetype anchors with a lower nesting depth *except* that we
  always prefer archetype anchors comprised of a sequence of
  associated types (i.e., no concrete type declarations), which is
  important for canonicalization.

Fixes SR-4757 / rdar://problem/31912838, as well as a regression
involving infinitely-recursive potential archetypes caused by the
previous commit.

a4e35ed151 [GSB] Remove unused form of addSameTypeRequirementDirect() 2017-06-23 10:00:11 -07:00
Doug Gregor
52e52b564b [GSB] Improve handling of conformances resolved by concrete types. 
Centralize and simplify the handling of conformance requirements
resolved by same-type-to-concrete requirements in a few ways:

* Always store a ProtocolConformanceRef in via-superclass and
  via-concrete requirement sources, so we never lose this information.

* When concretizing a nested type based on its parent, use the
  via-concrete conformance information rather than performing lookup
  again, simplifying this operation considerably and avoiding
  redundant lookups.

* When adding a conformance requirement to a potential archetype that
  is equivalent to a concrete type, attempt to find and record the
  conformance.

Fixes SR-4295 / rdar://problem/31372308.

Add test case for crash triggered in `swift::TypeChecker::validateDecl(...)`.

Current number of unresolved compiler crashers: 39 (5565 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `DeclBits.BeingValidated != ibv` added on 2016-12-04 by you in commit 4ed17f0f6 :-)

Assertion failure in [`include/swift/AST/Decl.h (line 821)`](53f68d7e4b/include/swift/AST/Decl.h (L821)):

```
Assertion `DeclBits.BeingValidated != ibv' failed.

When executing: void swift::Decl::setIsBeingValidated(bool)
```

Assertion context:

```c++
    return DeclBits.BeingValidated;
  }

  /// Toggle whether or not the declaration is being validated.
  void setIsBeingValidated(bool ibv = true) {
    assert(DeclBits.BeingValidated != ibv);
    DeclBits.BeingValidated = ibv;
    if (ibv) {
      DeclBits.ValidationStarted = true;
    }
  }

0b0f032d8f [swiftc (32 vs. 5563)] Add crasher in swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete 
Add test case for crash triggered in `swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete`.

Current number of unresolved compiler crashers: 32 (5563 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `conformance->isConcrete() || Concrete->isExistentialType()` added on 2017-02-23 by you in commit cbbf4154 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 3371)`](c21699b4e5/lib/AST/GenericSignatureBuilder.cpp (L3371)):

```
Assertion `conformance->isConcrete() || Concrete->isExistentialType()' failed.

When executing: ConstraintResult swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete(swift::GenericSignatureBuilder::PotentialArchetype *, swift::Type, const swift::GenericSignatureBuilder::RequirementSource *)
```

Assertion context:

```c++
    }

    conformances.insert({protocol, *conformance});

    // Abstract conformances are acceptable for existential types.
    assert(conformance->isConcrete() || Concrete->isExistentialType());

    // Update the requirement source now that we know it's concrete.
    // FIXME: Bad concrete source info.
    auto concreteSource = Source->viaConcrete(*this,
                                              conformance->isConcrete()
```

a2181092fb AST: Tweak a concrete-nested-type-of-archetype hack slightly 
When an archetype conforms to a protocol abstractly (ie, it is
not class-constrained and we don't have any further information
other than that it conforms), we can recover nested types,
but we cannot recover the conformance of those nested types
to protocols if those conformances are concrete (the nested
type might be concrete, or it might be a class-constrained
archetype).

To work around this, we added a hack where if the conformance
lookup in the SubstitutionMap fails, we fall back to the module.

This is horrible and unprincipled, but has to remain in place
until more infrastructure is plumbed through.

Commit 620db5f74c made this
workaround apply in fewer cases, so that we could still catch
cases where the SubstitutionMap was constructed with missing
conformances.

Unfortunately this workaround didn't handle the case where the
nested type was an archetype with a superclass constraint.

This will all go away soon, but for now tweak the logic a bit,
since I really want to keep the "narrow" workaround in place
and not the general fallback, otherwise we run the risk of
SubstitutionMap conformance lookup bitrotting completely.

Fixes <https://bugs.swift.org/browse/SR-4088> and
<rdar://problem/32773028>.

fe7ba8b79b [GSB] Pull typo correction for nested types into delayed reqs handling. 
Rather than performing typo correction at the very end of finalize(),
do it as part of delayed requirement handling when we cannot otherwise
make progress. This is a cleaner way to cope with typo correction that
gives us a better chance of getting to a sane result.

Fixes rdar://problem/31048352 by eliminating the need for tracking the
number of unresolved potential archetypes altogether. Fixes
rdar://problem/32077627.

8740ac2ef7 [swiftc (26 vs. 5563)] Add crasher in swift::TypeChecker::validateDecl(...) 
Add test case for crash triggered in `swift::TypeChecker::validateDecl(...)`.

Current number of unresolved compiler crashers: 26 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasInterfaceType() && "No interface type was set"` added on 2016-12-04 by you in commit c1a21613 :-)

Assertion failure in [`lib/AST/Decl.cpp (line 1813)`](1a9ccd347c/lib/AST/Decl.cpp (L1813)):

```
Assertion `hasInterfaceType() && "No interface type was set"' failed.

When executing: swift::Type swift::ValueDecl::getInterfaceType() const
```

Assertion context:

```c++
bool ValueDecl::hasInterfaceType() const {
  return !TypeAndAccess.getPointer().isNull();
}

Type ValueDecl::getInterfaceType() const {
  assert(hasInterfaceType() && "No interface type was set");
  return TypeAndAccess.getPointer();
}

void ValueDecl::setInterfaceType(Type type) {
  // lldb creates global typealiases with archetypes in them.

Add test case for crash triggered in `swift::ProtocolDecl::requiresClassSlow(...)`.

Current number of unresolved compiler crashers: 22 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `type && "Should have type checked inheritance clause by now"` added on 2017-04-28 by you in commit 0d4a0b7d :-)

Assertion failure in [`lib/AST/Decl.cpp (line 2989)`](c9b59ed644/lib/AST/Decl.cpp (L2989)):

```
Assertion `type && "Should have type checked inheritance clause by now"' failed.

When executing: bool swift::ProtocolDecl::requiresClassSlow()
```

Assertion context:

```c++

  // Otherwise, check if the inheritance clause contains a
  // class-constrained existential.
  //
  // FIXME: Use the requirement signature if available.
  ProtocolDeclBits.RequiresClass = false;
  for (auto inherited : getInherited()) {
    auto type = inherited.getType();
    assert(type && "Should have type checked inheritance clause by now");
    if (type->isExistentialType()) {
      auto layout = type->getExistentialLayout();

aacc765244 [swiftc (21 vs. 5563)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 21 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"` added on 2017-02-22 by you in commit fdb0a186 :-)

Assertion failure in [`lib/AST/Type.cpp (line 1093)`](ca3227f93c/lib/AST/Type.cpp (L1093)):

```
Assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"' failed.

When executing: swift::CanType swift::TypeBase::getCanonicalType()
```

Assertion context:

```c++

  case TypeKind::GenericTypeParam: {
    GenericTypeParamType *gp = cast<GenericTypeParamType>(this);
    auto gpDecl = gp->getDecl();
    assert(gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth &&
           "parameter hasn't been validated");
    Result = GenericTypeParamType::get(gpDecl->getDepth(), gpDecl->getIndex(),
                                       gpDecl->getASTContext());
    break;
  }

3663c36284 IRGen: Begin NSObject subclass layout with an NSObject 'isa' header only. 
We would lay out all classes starting with a Swift-style two-word header, even classes that inherit NSObject and therefore don't have Swift refcounting. The ObjC runtime would slide our ivars down for us at realization time, but it's nice to avoid unnecessarily dirtying memory in the not-uncommon case of direct NSObject subclasses.

b44f24dc2d [Type checker] Re-validate typealiases in protocols after protocol validation. 
Validation for typealiases in protocols is... odd. It needs to avoid
depending on the whole protocol being validated, so it does an initial
validation that can leave nested types of Self (and other associated
types) somewhat unresolved. In these cases, do something icky but
partially effective: when we resolve the protocol, go back and clean
up the types of these typealiases.

A better solution would allow us to use the types of these typealiases
within the Generic Signature Builder without recording them in the AST
as "the interface type", so there's no way unresolved nested types
could be found (and, therefore, nothing to "fix up" later). Howwever,
that's a more significant undertaking.

Fixes rdar://problem/32287795.

773d7b3225 Sema: Remove more methods from GenericTypeResolver 
resolveGenericTypeParamType(), resolveTypeOfDecl() and
resolveTypeOfContext() would all take the type of a
declaration, and optionally map it into context.

Replace them with a mapTypeIntoContext() that takes a
type and either returns it verbatim or maps it into
context.

01b45a245c Fold ConstraintSolver::coerceToRValue() into TypeChecker::coerceToRValue() 
ConstraintSolver::coerceToRValue() missed a bunch of cases where we
should be dealing with lvalues, e.g., tuples, "try" expressions, and
so on. Extend TypeChecker::coerceToRValue() to deal with the
expression type side-tables and ConstraintSolver::coerceToRValue() to
it.

Fixes rdar://problem/32700180, a crash-on-valid.

65c3565c2d Sema: Fix failure to produce diagnostics when 'is' casts are involved 
When re-typechecking an expression during diagnostics, we begin by
erasing all the types in the expression. However, any expressions
created as part of applying the solution will remain.

CSGen was doing the wrong thing when it encountered EnumIsCaseExpr,
which can only appear in already-type checked ASTs.

Returning expr->getType() is not correct, because the type is not
yet set; returning a null type is intended to signal that a
diagnostic was already emitted, which causes Sema to stop
type checking.

The end result is that certain combinations of invalid code with
an 'is' cast nested inside would crash either the AST verifier
(with asserts on) or in SILGen (with asserts off), because we
would stop trying to diagnose the issue prematurely, and possibly
not emit a diagnostic at all.

Fixes <https://bugs.swift.org/browse/SR-5050> and
<rdar://problem/32487948>.
