Argyrios Kyrtzidis 19b66a5e32 In a declarator, consider an identifier a constructor only if it is followed by '('.
Previously:

class C {
  int C;  // Declarator::SetConstructor was called here.
};

Argyrios Kyrtzidis e442635c37 Changes in preparation for nested-name-specifiers.
-When parsing declarators, don't depend on "CurScope->isCXXClassScope() == true" for constructors/destructors
-For C++ member declarations, don't depend on "Declarator.getContext() == Declarator::MemberContext"

Douglas Gregor dbc5daf058 Parsing, ASTs, and semantic analysis for the declaration of conversion
functions in C++, e.g.,

  struct X {
    operator bool() const;
  };

Note that these conversions don't actually do anything, since we don't
yet have the ability to use them for implicit or explicit conversions.

Douglas Gregor 11d0c4c098 Parsing, ASTs, and semantic analysis for the declaration of overloaded
operators in C++. Overloaded operators can be called directly via
their operator-function-ids, e.g., "operator+(foo, bar)", but we don't
yet implement the semantics of operator overloading to handle, e.g.,
"foo + bar".

Douglas Gregor 831c93f6c0 Parsing, representation, and preliminary semantic analysis of destructors.
Implicit declaration of destructors (when necessary).

Extended Declarator to store information about parsed constructors
and destructors; this will be extended to deal with declarators that
name overloaded operators (e.g., "operator +") and user-defined
conversion operators (e.g., "operator int").

Douglas Gregor 66583c5ff3 Implement C++ DR 106 and C++ DR 540, both of which deal with
reference-collapsing. 

Implement diagnostic for formation of a reference to cv void.

Drop cv-qualifiers added to a reference type when the reference type
comes from a typedef.

Douglas Gregor 61956c460a Add support for parsing and representing C++ constructor declarations.
Notes:
  - Constructors are never found by name lookup, so they'll never get
    pushed into any scope. Instead, they are stored as an 
    OverloadedFunctionDecl in CXXRecordDecl for easy overloading.
  - There's a new action isCurrentClassName that determines whether an
    identifier is the name of the innermost class currently being defined;
    we use this to identify the declarator-id grammar rule that refers to 
    a type-name. 
  - MinimalAction does *not* support parsing constructors.
  - We now handle virtual and explicit function specifiers.

Douglas Gregor 8e1cf608dc Implement initialization of a reference (C++ [dcl.init.ref]) as part
of copy initialization. Other pieces of the puzzle:

  - Try/Perform-ImplicitConversion now handles implicit conversions
    that don't involve references.
  - Try/Perform-CopyInitialization uses
    CheckSingleAssignmentConstraints for C. PerformCopyInitialization
    is now used for all argument passing and returning values from a
    function.
  - Diagnose errors with declaring references and const values without
    an initializer. (Uses a new Action callback, ActOnUninitializedDecl).
  
We do not yet have implicit conversion sequences for reference
binding, which means that we don't have any overloading support for
reference parameters yet.

2008-10-20 04:57:38 +00:00
Chris Lattner 8ff2c6c9f0 Fix a parser bug where we let attributes interfere with our disambiguation
of whether a '(' was a grouping paren or the start of a function declarator.
This is PR2796.

Now we eat the attribute before deciding whether the paren is grouping or
not, then apply it to the resultant decl or to the first argument as needed.

One somewhat surprising aspect of this is that attributes interact with
implicit int in cases like this:

void a(x, y) // k&r style function
void b(__attribute__(()) x, y); // function with two implicit int arguments
void c(x, __attribute__(()) y); // error, can't have attr in identifier list.

Fun stuff.

Argyrios Kyrtzidis 9a1191c047 Implement support for C++ direct initializers in declarations, e.g. "int x(1);".
This is how this kind of initializers appear in the AST:
-The Init expression of the VarDecl is a functional type construction (of the VarDecl's type).
-The new VarDecl::hasCXXDirectInitializer() returns true.

e.g, for "int x(1);":
-VarDecl 'x' has Init with expression "int(1)" (CXXFunctionalCastExpr).
-hasCXXDirectInitializer() of VarDecl 'x' returns true.

A major benefit is that clients that don't particularly care about which exactly form was the initializer can handle both cases without special case code.
Note that codegening works now for "int x(1);" without any changes to CodeGen.

2008-08-05 16:28:08 +00:00
Daniel Dunbar 4983df37a7 Add more Parser/Sema support for GCC asm-label extension.
- ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

Chris Lattner d7352d6801 minor cleanup to the actions interface to pass around SmallVectorImpl instead
of a specific smallvector size.

Fix protocol lists to pass down proper location info, so we get diagnostics

@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^

Douglas Gregor 556877c1e6 This patch adds very basic support for parsing and type-checking class
inheritance in C++. It'll parse the base-specifier list, e.g.,

 class D : public B1, virtual public B2 { };

and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

Chris Lattner 861a226586 This patch is just the easy part of the class names patch, which
allows the parsing of "class" in addition to "struct" and "union" to
declare a record.  So this patch allows:

 class C { };
 class C c1;

But it does not contain the lookup bits, so this won't work yet:

 C c2;

2008-04-10 16:37:40 +00:00
Chris Lattner a12405b0ef refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
declarators.  This allows the clients (C structs, objc classes, objc 
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.

This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating 
   AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.
