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

2008-11-18Add hooks to use PTHLexer::Lex instead of Lexer::Lex when CurLexer is null.Ted Kremenek
Performance tests on Cocoa.h (using the regular Lexer) shows no performance difference. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59479 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18Added conditional guard 'if (CurLexer)' when using SetCommentRetentionState().Ted Kremenek
This is because the PTHLexer will not support this method. Performance testing on preprocessing Cocoa.h shows that this results in a negligible performance difference (less than 1%). I tried making Lexer::SetCommentRetentionState() an out-of-line function (a precursor to making it a virtual function in PreprocessorLexer) and noticed a 1% decrease in speed (it is called in a hot part of the Preprocessor). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59477 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Change a bunch of uses of 'CurLexer->' to 'CurPPLexer->', which should be theTed Kremenek
alias for the current PreprocessorLexer. No functionality change. Performance testing shows this results in no performance degradation when preprocessing Cocoa.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59474 91177308-0d34-0410-b5e6-96231b3b80d8

PreprocessorLexer, which will either be a 'Lexer' or 'PTHLexer'. - Added stub field 'CurPTHLexer' to keep track of the current PTHLexer. - Modified IncludeStackInfo to track both the current PTHLexer and current PreprocessorLexer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59472 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
2008-11-17Fold assertion into second valid else branch. This removes a compiler warningTed Kremenek
where the control reaches the end of a non-void function and also allows the compiler to generate better code. When this assertion is false we can easily add more else cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59468 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
