2013-04-15Revert "Speed-up ObjCMethodDecl::getOverriddenMethods()."Argyrios Kyrtzidis
This reverts commit r179436. Due to caching, it was possible that we could miss overridden methods that were introduced by categories later on.

2013-04-11Force a load when creating a reference to a temporary copied from a bitfield.Jordan Rose
For this source: const int &ref = someStruct.bitfield; We used to generate this AST: DeclStmt [...] `-VarDecl [...] ref 'const int &' `-MaterializeTemporaryExpr [...] 'const int' lvalue `-ImplicitCastExpr [...] 'const int' lvalue <NoOp> `-MemberExpr [...] 'int' lvalue bitfield .bitfield [...] `-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X' Notice the lvalue inside the MaterializeTemporaryExpr, which is very confusing (and caused an assertion to fire in the analyzer - PR15694). We now generate this: DeclStmt [...] `-VarDecl [...] ref 'const int &' `-MaterializeTemporaryExpr [...] 'const int' lvalue `-ImplicitCastExpr [...] 'int' <LValueToRValue> `-MemberExpr [...] 'int' lvalue bitfield .bitfield [...] `-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X' Which makes a lot more sense. This allows us to remove code in both CodeGen and AST that hacked around this special case. The commit also makes Clang accept this (legal) C++11 code: int &&ref = std::move(someStruct).bitfield PR15694 / <rdar://problem/13600396> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179250 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09[analyzer] Replace isIntegerType() with isIntegerOrEnumerationType().Jordan Rose
Previously, the analyzer used isIntegerType() everywhere, which uses the C definition of "integer". The C++ predicate with the same behavior is isIntegerOrUnscopedEnumerationType(). However, the analyzer is /really/ using this to ask if it's some sort of "integrally representable" type, i.e. it should include C++11 scoped enumerations as well. hasIntegerRepresentation() sounds like the right predicate, but that includes vectors, which the analyzer represents by its elements. This commit audits all uses of isIntegerType() and replaces them with the general isIntegerOrEnumerationType(), except in some specific cases where it makes sense to exclude scoped enumerations, or any enumerations. These cases now use isIntegerOrUnscopedEnumerationType() and getAs<BuiltinType>() plus BuiltinType::isInteger(). isIntegerType() is hereby banned in the analyzer - lib/StaticAnalysis and include/clang/StaticAnalysis. :-) Fixes real assertion failures.

functions to the conversion function set eagerly. This slightly propagates an existing hack that delays when we provide access specifiers for the visible conversion functions of a class by copying the available access specifier early. The only client this affects is LLDB, which tends to discover and add conversion functions after the class is technically "complete". As such, the only observable difference is in LLDB, so the testing will go there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179029 91177308-0d34-0410-b5e6-96231b3b80d8
