2008-11-19rewrite FormatDiagnostic to be less gross and a lot more efficient.Chris Lattner
This also makes it illegal to have bare '%'s in diagnostics. If you want a % in a diagnostic, use %%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59596 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-19implement a transparent optimization with the diagnostics stuff:Chris Lattner
const char*'s are now not converted to std::strings when the diagnostic is formed, we just hold onto their pointer and format as needed. This commit makes DiagnosticClient::FormatDiagnostic even more of a mess, I'll fix it in the next commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59593 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19remove one more old-style Diag method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59589 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Switch several more Sema Diag methods over. This simplifies theChris Lattner
__builtin_prefetch code to only emit one diagnostic per builtin_prefetch. While this has nothing to do with the rest of the patch, the code seemed like overkill when I was updating it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59588 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Built-in equality and relational operators have return type "bool" in C++,Douglas Gregor
not "int". Fix a typo in the promotion of enumeration types that was causing some integral promotions to look like integral conversions (leading to extra ambiguities in overload resolution). Check for "acceptable" overloaded operators based on the types of the arguments. This is a somewhat odd check that is specified by the standard, but I can't see why it actually matters: the overload candidates it suppresses don't seem like they would ever be picked as the best candidates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59583 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-19- Move static function IsNonPragmaNonMacroLexer into Preprocessor.h.Ted Kremenek
- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry (simplifies some uses). - Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile. Performance testing of -Eonly on Cocoa.h shows no performance regression because of this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59574 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59571 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Partial expansion of C++ operator overloading (for binary operators)Douglas Gregor
to support operators defined as member functions, e.g., struct X { bool operator==(X&); }; Overloading with non-member operators is supported, and the special rules for the implicit object parameter (e.g., the ability for a non-const *this to bind to an rvalue) are implemented. This change also refactors and generalizes the code for adding overload candidates for overloaded operator calls (C++ [over.match.expr]), both to match the rules more exactly (name lookup of non-member operators actually ignores member operators) and to make this routine more reusable for the other overloaded operators. Testing for the initialization of the implicit object parameter is very light. More tests will come when we get support for calling member functions directly (e.g., o.m(a1, a2)). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59564 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18Fix <rdar://problem/6329769> [sema] crash on duplication definition of ↵Steve Naroff
interface with protocols. As soon as we detect duplicate interfaces, discontinue further semantic checks (returning the original interface). This is now consistent with how we handle protocols (and less error prone in general). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59541 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18As threatened previously: consolidate name lookup and the creation ofDouglas Gregor
DeclRefExprs and BlockDeclRefExprs into a single function Sema::ActOnDeclarationNameExpr, eliminating a bunch of duplicate lookup-name-and-check-the-result code. Note that we still have the three parser entry points for identifiers, operator-function-ids, and conversion-function-ids, since the parser doesn't (and shouldn't) know about DeclarationNames. This is a Good Thing (TM), and there will be more entrypoints coming (e.g., for C++ pseudo-destructor expressions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59527 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

2008-11-18remove the last couple obsolete forms of Parser::Diag.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59510 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
2008-11-18This 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

2008-11-18eliminate dependence of strange "Diagnostic::Report" method, Chris Lattner

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
