2008-11-19Fix <rdar://problem/6150376> [sema] crash on invalid message send.Steve Naroff
The core fix in Sema::ActOnClassMessage(). All the other changes have to do with passing down the SourceLocation for the receiver (to properly position the cursor when producing an error diagnostic). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59639 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Added operator overloading for unary operators, post-increment, andDouglas Gregor
post-decrement, including support for generating all of the built-in operator candidates for these operators. C++ and C have different rules for the arguments to the builtin unary '+' and '-'. Implemented both variants in Sema::ActOnUnaryOp. In C++, pre-increment and pre-decrement return lvalues. Update Expr::isLvalue accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59638 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Fix this:Argyrios Kyrtzidis
With this snippet: void f(a::b); An assert is hit: Assertion failed: CachedTokens[CachedLexPos-1].getLocation() == Tok.getAnnotationEndLoc() && "The annotation should be until the most recent cached token", file ..\..\lib\Lex\PPCaching.cpp, line 98 Introduce Preprocessor::RevertCachedTokens that reverts a specific number of tokens when backtracking is enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59636 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Remove Preprocessor::CacheTokens boolean data member. The same functionality ↵Argyrios Kyrtzidis
can be provided by using Preprocessor::isBacktrackEnabled(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59631 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-19Fix redundant load of bit-fields on assignment (to get the updatedDaniel Dunbar
value). - Use extra argument to EmitStoreThroughLValue to provide place to write update bit-field value if caller requires it. - This fixes several FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59615 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

2008-11-19Switch 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

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
