* This reworks some of the Diagnostic interfaces a bit to change how diagnosticsChris Lattner2008-11-1817-205/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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?! llvm-svn: 59502

* Added conditional guard 'if (CurLexer)' when using SetCommentRetentionState().Ted Kremenek2008-11-181-6/+6
| | | | | | | | | | | | 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). llvm-svn: 59477

| | | | | | | | | | | | | new CycleBound value. Instead, just update CycleBound on each call. Also, make ReleasePred and ReleaseSucc methods more consistent accross the various schedulers. This also happens to make ScheduleDAGRRList's CycleBound computation somewhat more interesting, though it still doesn't have any noticeable effect, because no current targets that use the register-pressure reduction scheduler provide pipeline models. llvm-svn: 59475

* Updated IdentifierResolver to deal with DeclarationNames. The names ofDouglas Gregor2008-11-1716-70/+223
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 59462
