2009-12-04Fix for PR5679: make __builtin_prefetch a bit more flexible in what it acceptsEli Friedman
as a constant integer. Also, some minor cleanup and improvements to the diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90504 91177308-0d34-0410-b5e6-96231b3b80d8

create the enum type in the same scope as you would a record type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90500 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03A new helper function to set various bits in the class whenFariborz Jahanian
a new virtual function is declared/instantiated. it is used in couple of places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90470 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03Unify the end-of-class code paths used by the parser and templateDouglas Gregor
instantiation, to ensure that we mark class template specilizations as abstract when we need to and perform checking of abstract classes. Also, move the checking that determines whether we are creating a variable of abstract class type *after* we check whether the type is complete. Otherwise, we won't see when we have an abstract class template specialization that is implicitly instantiated by this declaration. This is the "something else" that Sebastian had noted earlier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90467 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03When instantiating a class, if a base specifier is not dependent we still ↵Anders Carlsson
need to copy its attributes down to the instantiated class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90463 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03When we're building a CXXExprWithTemporaries, only include thoseDouglas Gregor
temporaries that are within our current evaluation context. That way, nested evaluation contexts (e.g., within a sizeof() expression) won't see temporaries from outer contexts. Also, make sure to push a new evaluation context when instantiating the initializer of a variable; this may be an unevaluated context or a potentially-evaluated context, depending on whether it's an in-class initializer or not. Fixes PR5672. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90460 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03Honor using declarations in overload resolution. Most of the code forJohn McCall
overloaded-operator resolution is wildly untested, but the parallel code for methods seems to satisfy some trivial tests. Also change some overload-resolution APIs to take a type instead of an expression, which lets us avoid creating a spurious CXXThisExpr when resolving implicit member accesses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90410 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03Stop stripping UnresolvedUsingDecls out of LookupResults that have otherJohn McCall
results in them (which we were doing intentionally as a stopgap). Fix an DeclContext lookup-table ordering problem which was causing UsingDecls to show up incorrectly when looking for ordinary results. And oh hey Clang-Code-Syntax passes now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90367 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Improve source location information for C++ member initializers in aDouglas Gregor
constructor, by keeping the DeclaratorInfo* rather than just the type and a single location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90355 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Use a more rigorous definition of 'class member'. I don't have any evidenceJohn McCall
that this was causing a problem, but it could have. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90343 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Recognize that EnumConstantDecls can be found by lookup and are not instanceJohn McCall
members. Fixes PR5667. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90341 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02In Sema, whenever we think that a function is going to cause a vtable to be ↵Anders Carlsson
generated, we mark any virtual implicit member functions as referenced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90327 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90313 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Rip out the last remaining implicit use of OverloadedFunctionDecl in Sema:John McCall
LookupResult::getAsSingleDecl() is no more. Shift Sema::LookupSingleName to return null on overloaded results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90309 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Push overloaded function templates through the parser using a totally differentJohn McCall
leaked data structure than before. This kills off the last remaining explicit uses of OverloadedFunctionDecl in Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90306 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Fix another "operator delete missing" crash: make sure we don't checkEli Friedman
isVirtual() before we've actually calculated whether the destructor is virtual. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90303 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Make sure to call AddOverriddenMethods for implicit copy assignment operators;Eli Friedman
it's rare, but possible, for the difference to be significant. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90301 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Stop trying to analyze class-hierarchies for dependently-scoped id-expressions;John McCall
there's nothing interesting we can say now that we're correctly not requiring the qualifier to name a known base class in dependent contexts. Require scope specifiers on member access expressions to name complete types if they're not dependent; delay lookup when they are dependent. Use more appropriate diagnostics when qualified implicit member access expressions find declarations from unrelated classes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90289 91177308-0d34-0410-b5e6-96231b3b80d8

Gets clang-on-clang passing again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90270 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Rework how we support C++ implicit member accesses. If we can resolve anJohn McCall
implicit member access to a specific declaration, go ahead and create it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as appropriate. Otherwise, create an UnresolvedMemberExpr or DependentScopeMemberExpr with a null base expression. By representing implicit accesses directly in the AST, we get the ability to correctly delay the decision about whether it's actually an instance member access or not until resolution is complete. This permits us to correctly avoid diagnosing the 'problem' of 'MyType::foo()' where the relationship to the type isn't really known until instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90266 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Add {ExternalSemaSource,SemaConsumer}::ForgetSema callback, and update PCHReaderDaniel Dunbar
to use it so it at least won't try to access Sema once it is gone. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90261 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Funtion templates and function template specializations do notDouglas Gregor
override virtual functions. Also, eliminate a (now redundant) call to AddOverriddenMethods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90242 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Move the checking of overridden virtual functions into the code pathDouglas Gregor
common to both parsing and template instantiation, so that we'll find overridden virtuals for member functions of class templates when they are instantiated. Additionally, factor out the checking for pure virtual functions, so that it will be executed both at parsing time and at template instantiation time. These changes fix PR5656 (for real), although one more tweak w.r.t. member function templates will be coming along shortly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90241 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Don't automatically assume that an id-expression refers to aDouglas Gregor
ValueDecl, because that isn't always the case in ill-formed code. Diagnose a common mistake (forgetting to provide a template argument list for a class template, PR5655) and dyn_cast so that we handle the general problem of referring to a non-value declaration gracefully. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90239 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-30Eliminate the use of OverloadedFunctionDecl in member expressions.John McCall
Create a new UnresolvedMemberExpr for these lookups. Assorted hackery around qualified member expressions; this will all go away when we implement the correct (i.e. extremely delayed) implicit-member semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90161 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-29Don't call Decl::CollectingStats(false) and Stmt::CollectingStats(false). ↵Kovarththanan Rajaratnam
When called with false these functions return whether statistics are enabled. They don't change any state. Since we're not using the return value avoid calling them in the first place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90077 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-28Add Parser support for C++0x literal operators ('operator "" i').Sean Hunt
DeclarationName can't handle them yet, so right now Parser just errors out on them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90027 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-27More work on ScalarExprEmitter::EmitCastExpr: for every cast kind, eitherEli Friedman
implement it explicitly or assert that it doesn't make sense for a scalar. This caught a couple interesting issues: one, CK_BaseToDerivedMemberPointer casts were getting silently miscompiled, and two, Sema was constructing some strange implicit casts of type CK_UserDefinedConversion. The change in SemaExprCXX makes sure the cast kinds are getting set correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89987 91177308-0d34-0410-b5e6-96231b3b80d8

maintains a stack of evaluation contexts rather than having the parser do it. This change made it simpler to track in which contexts temporaries were created, so that we could... "Forget" about temporaries created within unevaluated contexts, so that we don't build a CXXExprWithTemporaries and, therefore, destroy the integral-constness of our expressions.
