2008-11-23Convert IdentifierInfo's to be printed the same as DeclarationNames Chris Lattner
with implicit quotes around them. This has a bunch of follow-on effects and requires tweaking to a whole lot of code. This causes a regression in two tests (xfailed) by causing it to emit things like: Line 10: duplicate interface declaration for category 'MyClass1' ('Category1') instead of: Line 10: duplicate interface declaration for category 'MyClass1(Category1)' I will fix this in a follow-up commit. As part of this, I had to start switching stuff to use ->getDeclName() instead of Decl::getName() for consistency. This is good, but I was planning to do this as an independent patch. There will be several follow-on patches to clean up some of the mess, but this patch is already too big. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59917 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Implementation of new and delete parsing and sema.Sebastian Redl
This version uses VLAs to represent arrays. I'll try an alternative way next, but I want this safe first. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59835 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18Extend DeclarationName to support C++ overloaded operators, e.g.,Douglas Gregor
operator+, directly, using the same mechanism as all other special names. Removed the "special" identifiers for the overloaded operators from the identifier table and IdentifierInfo data structure. IdentifierInfo is back to representing only real identifiers. Added a new Action, ActOnOperatorFunctionIdExpr, that builds an expression from an parsed operator-function-id (e.g., "operator +"). ActOnIdentifierExpr used to do this job, but operator-function-ids are no longer represented by IdentifierInfo's. Extended Declarator to store overloaded operator names. Sema::GetNameForDeclarator now knows how to turn the operator name into a DeclarationName for the overloaded operator. Except for (perhaps) consolidating the functionality of ActOnIdentifier, ActOnOperatorFunctionIdExpr, and ActOnConversionFunctionExpr into a common routine that builds an appropriate DeclRefExpr by looking up a DeclarationName, all of the work on normalizing declaration names should be complete with this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59526 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Change a couple of the Parser::Diag methods to return DiagnosticInfoChris Lattner
and let the clients push whatever they want into the DiagnosticInfo instead of hard coding a few forms. Also switch various clients to use Diag(Tok, ...) instead of Diag(Tok.getLocation(), ...) as the canonical form to simplify the code a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Eliminate all of the placeholder identifiers used for constructors,Douglas Gregor
destructors, and conversion functions. The placeholders were used to work around the fact that the parser and some of Sema really wanted declarators to have simple identifiers; now, the code that deals with declarators will use DeclarationNames. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59469 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-12Don't build identifiers for C++ constructors, destructors, orDouglas Gregor
conversion functions. Instead, we just use a placeholder identifier for these (e.g., "<constructor>") and override NamedDecl::getName() to provide a human-readable name. This is one potential solution to the problem; another solution would be to replace the use of IdentifierInfo* in NamedDecl with a different class that deals with identifiers better. I'm also prototyping that to see how it compares, but this commit is better than what we had previously. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59193 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-06Parsing, ASTs, and semantic analysis for the declaration of overloadedDouglas Gregor
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". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58817 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-05Parsing, representation, and preliminary semantic analysis of destructors.Douglas Gregor
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"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58767 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58612 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31Add support for parsing and representing C++ constructor declarations.Douglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58499 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-29Implement initialization of a reference (C++ [dcl.init.ref]) as partDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58353 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-20Fix a parser bug where we let attributes interfere with our disambiguationChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57790 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-06Implement support for C++ direct initializers in declarations, e.g. "int x(1);".Argyrios Kyrtzidis
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57178 91177308-0d34-0410-b5e6-96231b3b80d8
