2009-12-29Correctly refer to element CVR qualifications when determining if a type isChandler Carruth
more or less cv-qualified than another during implicit conversion and overload resolution ([basic.type.qualifier] p5).

2009-12-22Stop diagnosing the use of inner classes as friends. ddunbar asked whetherJohn McCall
this was useful, and on review Doug and I decided it was probably on the level of a bug in the standard and therefore not worth a warning even in -pedantic.

2009-12-19Refactor to remove more dependencies on PreDeclaratorDC. I seem to have madeJohn McCall

2009-12-18Switch the initialization required by return statements over to theDouglas Gregor
new InitializationSequence. This fixes some bugs (e.g., PR5808), changed some diagnostics, and caused more churn than expected. What's new: - InitializationSequence now has a "C conversion sequence" category and step kind, which falls back to - Changed the diagnostics for returns to always have the result type of the function first and the type of the expression second. CheckSingleAssignmentConstraints to peform checking in C. - Improved ASTs for initialization of return values. The ASTs now capture all of the temporaries we need to create, but intentionally do not bind the tempoary that is actually returned, so that it won't get destroyed twice. - Make sure to perform an (elidable!) copy of the class object that is returned from a class. - Fix copy elision in CodeGen to properly see through the subexpressions that occur with elidable copies. - Give "new" its own entity kind; as with return values and thrown objects, we don't bind the expression so we don't call a destructor for it. Note that, with this patch, I've broken returning move-only types in C++0x. We'll fix it later, when we tackle NRVO. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91669 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-16Switch the C++ new expression over to InitializationSequence, ratherDouglas Gregor
than using its own partial implementation of initialization. Switched CheckInitializerTypes over to InitializedEntity/InitializationKind, to help move us closer to InitializationSequence. Added InitializedEntity::getName() to retrieve the name of the entity, for diagnostics that care about such things. Implemented support for default initialization in InitializationSequence. Clean up the determination of the "source expressions" for an initialization sequence in InitializationSequence::Perform. Taught CXXConstructExpr to store more location information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91492 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-11Check if the target of a using decl is already declared in this scope beforeJohn McCall
doing any of the other redeclaration checks. We were missing a few cases. Fixes PR 5752. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91096 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-11Implement access declarations. Most of the work here is parsing them, whichJohn McCall
is difficult because they're so terribly, terribly ambiguous. We implement access declarations in terms of using declarations, which is quite reasonable. However, we should really persist the access/using distinction in the AST and use the appropriate name in diagnostics. This isn't a priority, so I'll just file a PR and hope someone else does it. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91095 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-10Improve the diagnostic when a new declaration conflicts with a using shadowJohn McCall
declaration. Rename note_using_decl to note_using, which is possibly less confusing. Add a test for non-class-scope using decl collisions and be sure to note the case we can't diagnose yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91057 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-10Implement redeclaration checking and hiding semantics for using ↵John McCall
declarations. There are a couple of O(n^2) operations in this, some analogous to the usual O(n^2) redeclaration problem and some not. In particular, retroactively removing shadow declarations when they're hidden by later decls is pretty unfortunate. I'm not yet convinced it's worse than the alternative, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91045 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-09Reimplement reference initialization (C++ [dcl.init.ref]) using theDouglas Gregor
new notion of an "initialization sequence", which encapsulates the computation of the initialization sequence along with diagnostic information and the capability to turn the computed sequence into an expression. At present, I've only switched one CheckReferenceInit callers over to this new mechanism; more will follow. Aside from (hopefully) being much more true to the standard, the diagnostics provided by this reference-initialization code are a bit better than before. Some examples: p5-var.cpp:54:12: error: non-const lvalue reference to type 'struct Derived' cannot bind to a value of unrelated type 'struct Base' Derived &dr2 = b; // expected-error{{non-const lvalue reference to ... ^ ~ p5-var.cpp:55:9: error: binding of reference to type 'struct Base' to a value of type 'struct Base const' drops qualifiers Base &br3 = bc; // expected-error{{drops qualifiers}} ^ ~~ p5-var.cpp:57:15: error: ambiguous conversion from derived class 'struct Diamond' to base class 'struct Base': struct Diamond -> struct Derived -> struct Base struct Diamond -> struct Derived2 -> struct Base Base &br5 = diamond; // expected-error{{ambiguous conversion from ... ^~~~~~~ p5-var.cpp:59:9: error: non-const lvalue reference to type 'long' cannot bind to a value of unrelated type 'int' long &lr = i; // expected-error{{non-const lvalue reference to type ... ^ ~ p5-var.cpp:74:9: error: non-const lvalue reference to type 'struct Base' cannot bind to a temporary of type 'struct Base' Base &br1 = Base(); // expected-error{{non-const lvalue reference to ... ^ ~~~~~~ p5-var.cpp:102:9: error: non-const reference cannot bind to bit-field 'i' int & ir1 = (ib.i); // expected-error{{non-const reference cannot ... ^ ~~~~~~ p5-var.cpp:98:7: note: bit-field is declared here int i : 17; // expected-note{{bit-field is declared here}} ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90992 91177308-0d34-0410-b5e6-96231b3b80d8

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.
