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
2008-11-18This reworks some of the Diagnostic interfaces a bit to change how diagnosticsChris Lattner
are formed. In particular, a diagnostic with all its strings and ranges is now packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a ton of random stuff. This has the benefit of simplifying the interface, making it more extensible, and allowing us to do more checking for things like access past the end of the various arrays passed in. In addition to introducing DiagnosticInfo, this also substantially changes how Diagnostic::Report works. Instead of being passed in all of the info required to issue a diagnostic, Report now takes only the required info (a location and ID) and returns a fresh DiagnosticInfo *by value*. The caller is then free to stuff strings and ranges into the DiagnosticInfo with the << operator. When the dtor runs on the DiagnosticInfo object (which should happen at the end of the statement), the diagnostic is actually emitted with all of the accumulated information. This is a somewhat tricky dance, but it means that the accumulated DiagnosticInfo is allowed to keep pointers to other expression temporaries without those pointers getting invalidated. This is just the minimal change to get this stuff working, but this will allow us to eliminate the zillions of variant "Diag" methods scattered throughout (e.g.) sema. For example, instead of calling: Diag(BuiltinLoc, diag::err_overload_no_match, typeNames, SourceRange(BuiltinLoc, RParenLoc)); We will soon be able to just do: Diag(BuiltinLoc, diag::err_overload_no_match) << typeNames << SourceRange(BuiltinLoc, RParenLoc)); This scales better to support arbitrary types being passed in (not just strings) in a type-safe way. Go operator overloading?! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59502 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Change the diagnostics interface to take an array of pointers to Chris Lattner
strings instead of array of strings. This reduces string copying in some not-very-important cases, but paves the way for future improvements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59494 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
2008-11-08Implement support for C++ nested-name-specifiers ('foo::bar::x') in the ↵Argyrios Kyrtzidis
Parser side. No Sema functionality change, just the signatures of the Action/Sema methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58913 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-05Initial implementation of parsing, semantic analysis, and AST-buildingDouglas Gregor
for constructor initializations, e.g., class A { }; class B : public A { int m; public: B() : A(), m(17) { }; }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58749 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57788 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

2008-08-14Change Parser & Sema to use interned "super" for comparions.Daniel Dunbar
- Added as private members for each because it is not clear where to put the common definition. Perhaps the IdentifierInfos all of these "pseudo-keywords" should be collected into one place (this would KnownFunctionIDs and Objective-C property IDs, for example). Remove Token::isNamedIdentifier. - There isn't a good reason to use strcmp when we have interned strings, and there isn't a good reason to encourage clients to do so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54794 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-05Add more Parser/Sema support for GCC asm-label extension.Daniel Dunbar
- 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... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54339 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-26Make Declarator::getDeclSpec() return a const reference to avoidChris Lattner

2008-06-24Add parsing support for C++ classes.Argyrios Kyrtzidis
Note that Parser::ParseCXXMemberSpecification is temporarily disabled until the Sema support is in place. Once ParseCXXMemberSpecification is enabled, the Parser/cxx-class.cpp test will pass. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52694 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-20Fix the scope of K&R-style argument declarations so that they don't Eli Friedman
extend beyond the end of the function. I'm not completely sure this is the right way to fix this bug, so someone familiar with the parser should double-check. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51311 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-08Add support for C++ default arguments, and rework Parse-Sema Chris Lattner
interaction for function parameters, fixing PR2046. Patch by Doug Gregor! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49369 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-05Fix handling of implicit int, resolving PR2012 and reverting (andChris Lattner
subsuming) my patch for PR1999. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49251 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-05Step #1 to fixing PR2012: c89 allows declspecs to be completely Chris Lattner
missing from function definitions only. If we see a function definiton with missing declspecs, just fudge in an int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49250 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
