2008-12-05Introduce basic support for dependent types, type-dependentDouglas Gregor
expressions, and value-dependent expressions. This permits us to parse some template definitions. This is not a complete solution; we're missing type- and value-dependent computations for most of the expression types, and we're missing checks for dependent types and type-dependent expressions throughout Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60615 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-05Representation of template type parameters and non-type templateDouglas Gregor
parameters, with some semantic analysis: - Template parameters are introduced into template parameter scope - Complain about template parameter shadowing (except in Microsoft mode) Note that we leak template parameter declarations like crazy, a problem we'll remedy once we actually create proper declarations for templates. Next up: dependent types and value-dependent/type-dependent expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60597 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-24Change a whole lot of diagnostics to take QualType's directly Chris Lattner
instead of converting them to strings first. This also fixes a bunch of minor inconsistencies in the diagnostics emitted by clang and adds a bunch of FIXME's to DiagnosticKinds.def. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59948 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of Chris Lattner
uses of getName() with uses of getDeclName(). This upgrades a bunch of diags to take DeclNames instead of std::strings. This also tweaks a couple of diagnostics to be cleaner and changes CheckInitializerTypes/PerformInitializationByConstructor to pass around DeclarationNames instead of std::strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59947 91177308-0d34-0410-b5e6-96231b3b80d8

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

2008-11-18Extend 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

2008-11-17Eliminate 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
2008-11-17Updated IdentifierResolver to deal with DeclarationNames. The names ofDouglas Gregor
C++ constructors, destructors, and conversion functions now have a FETokenInfo field that IdentifierResolver can access, so that these special names are handled just like ordinary identifiers. A few other Sema routines now use DeclarationNames instead of IdentifierInfo*'s. To validate this design, this code also implements parsing and semantic analysis for id-expressions that name conversion functions, e.g., return operator bool(); The new parser action ActOnConversionFunctionExpr takes the result of parsing "operator type-id" and turning it into an expression, using the IdentifierResolver with the DeclarationName of the conversion function. ActOnDeclarator pushes those conversion function names into scope so that the IdentifierResolver can find them, of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59462 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-14Add a new expression node, CXXOperatorCallExpr, which expresses aDouglas Gregor
function call created in response to the use of operator syntax that resolves to an overloaded operator in C++, e.g., "str1 + str2" that resolves to std::operator+(str1, str2)". We now build a CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But only for binary operators, where we actually implement overloading) I decided *not* to refactor the current CallExpr to make it abstract (with FunctionCallExpr and CXXOperatorCallExpr as derived classes). Doing so would allow us to make CXXOperatorCallExpr a little bit smaller, at the cost of making the argument and callee accessors virtual. We won't know if this is going to be a win until we can parse lots of C++ code to determine how much memory we'll save by making this change vs. the performance penalty due to the extra virtual calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59306 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

2008-11-12Implement support for operator overloading using candidate operatorDouglas Gregor
functions for built-in operators, e.g., the builtin bool operator==(int const*, int const*) can be used for the expression "x1 == x2" given: struct X { operator int const*(); } x1, x2; The scheme for handling these built-in operators is relatively simple: for each candidate required by the standard, create a special kind of candidate function for the built-in. If overload resolution picks the built-in operator, we perform the appropriate conversions on the arguments and then let the normal built-in operator take care of it. There may be some optimization opportunity left: if we can reduce the number of built-in operator overloads we generate, overload resolution for these cases will go faster. However, one must be careful when doing this: GCC generates too few operator overloads in our little test program, and fails to compile it because none of the overloads it generates match. Note that we only support operator overload for non-member binary operators at the moment. The other operators will follow. As part of this change, ImplicitCastExpr can now be an lvalue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59148 91177308-0d34-0410-b5e6-96231b3b80d8
