Douglas Gregor b04675d112 Don't check initializers when there are dependent types or type-dependent expressions involved

Douglas Gregor 55ad91fecb Ultrasimplistic sketch for the parsing of C++ template-ids. This won't
become useful or correct until we (1) parse template arguments
correctly, (2) have some way to turn template-ids into types,
declarators, etc., and (3) have a real representation of templates.

Chris Lattner b6ec4e75ad Clean up the C89/C++ warnings about C99 array features to not
emit duplicate diags (some in parser and some in sema) and to
warn about use of typequals in array sizes.  This implements 
PR2759.

Douglas Gregor 4d87df5853 Delay parsing of default arguments of member functions until the class
is completely defined (C++ [class.mem]p2).

Reverse the order in which we process the definitions of member
functions specified inline. This way, we'll get diagnostics in the
order in which the member functions were declared in the class.

Douglas Gregor ad590506a7 Diagnose erroneous uses of out-of-line member definitions and scope
specifiers. Specifically: 
  * Determine when an out-of-line function definition does not match
    any declaration within the class or namespace (including coping
    with overloaded functions).
  * Complain about typedefs and parameters that have scope specifiers.
  * Complain about out-of-line declarations that aren't also
  definitions.
  * Complain about non-static data members being declared out-of-line.
  * Allow cv-qualifiers on out-of-line member function definitions.

Douglas Gregor 1349b457ee Place constructors and destructors into the DeclContext of the class,
just like all other members, and remove the special variables in
CXXRecordDecl to store them. This eliminates a lot of special-case
code for constructors and destructors, including
ActOnConstructor/ActOnDeclarator and special lookup rules in
LookupDecl. The result is far more uniform and manageable.

Diagnose the redeclaration of member functions.

Douglas Gregor 1d248c53ab In C++, set the type of each of the enumerators in an enumeration to
the type of the enumeration once the enumeration has been defined.

Fix the overloading test-case to properly create enums that promote
the way we want them to.

Implement C++0x promotions from enumeration types to long
long/unsigned long long. We're using these promotions in Carbon.h
(since long long is a common extension).

Douglas Gregor 7a4fad1b0b Address some comments on the name lookup/DeclContext patch from Chris
llvm-svn: 60897
2008-12-11 20:41:00 +00:00
Douglas Gregor 91f84216f7 Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
  * Make DeclContext the central data structure for storing and
    looking up declarations within existing declarations, e.g., members
    of structs/unions/classes, enumerators in C++0x enums, members of
    C++ namespaces, and (later) members of Objective-C
    interfaces/implementations. DeclContext uses a lazily-constructed
    data structure optimized for fast lookup (array for small contexts,
    hash table for larger contexts). 

  * Implement C++ qualified name lookup in terms of lookup into
    DeclContext.

  * Implement C++ unqualified name lookup in terms of
    qualified+unqualified name lookup (since unqualified lookup is not
    purely lexical in C++!)

  * Limit the use of the chains of declarations stored in
    IdentifierInfo to those names declared lexically.

  * Eliminate CXXFieldDecl, collapsing its behavior into
    FieldDecl. (FieldDecl is now a ScopedDecl).

  * Make RecordDecl into a DeclContext and eliminates its
    Members/NumMembers fields (since one can just iterate through the
    DeclContext to get the fields).

Douglas Gregor 85970ca84c Added a warning when referencing an if's condition variable in the
"else" clause, e.g.,

  if (int X = foo()) {
  } else {
    if (X) { // warning: X is always zero in this context
    }
  }

Fixes rdar://6425550 and lets me think about something other than
DeclContext.
