2011-12-21Implement a trivial, obvious optimization for deserialization ofDouglas Gregor
redeclaration chains: only ever have the reader search for redeclarations of the first (canonical) declaration, since we only ever record redeclaration ranges for the that declaration. Searching for redeclarations of non-canonical declarations will never find anything, so it's a complete waste of time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147055 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20[analyzer] Do not invalidate arguments when the parameter'sAnna Zaks
type is a pointer to const. (radar://10595327) The regions corresponding to the pointer and reference arguments to a function get invalidated by the calls since a function call can possibly modify the pointed to data. With this change, we are not going to invalidate the data if the argument is a pointer to const. This change makes the analyzer more optimistic in reporting errors.

2011-12-20When performing name lookup for a redeclaration, ignore moduleDouglas Gregor
visibility restrictions. This ensures that all declarations of the same entity end up in the same redeclaration chain, even if some of those declarations aren't visible. While this may seem unfortunate to some---why can't two C modules have different functions named 'f'?---it's an acknowedgment that a module does not introduce a new "namespace" of names. As part of this, stop merging the 'module-private' bit from previous declarations to later declarations, because we want each declaration in a module to stand on its own because this can effect, for example, submodule visibility. Note that this notion of names that are invisible to normal name lookup but are available for redeclaration lookups is how we should implement friend declarations and extern declarations within local function scopes. I'm not tackling that problem now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146980 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20Relax type checking for a few Neon intrinsics. <rdar://problem/10538555>Bob Wilson
Not long ago, I tightened up the type checking for pointer arguments of Neon intrinsics to match the specifications provided by ARM. One consequence was that it became impossible to access the unaligned versions of a few Neon load/store operations. Since there are just a few of these intrinsics where it makes a difference, I think it's better to relax the type checking than to either introduce new non-standard unaligned intrinsics or to disallow intrinsics for the unaligned operations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146963 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20Unlike in C++03, a constant-expression is not an unevaluated operand in C++11.Richard Smith
Split out a new ExpressionEvaluationContext flag for this case, and don't treat it as unevaluated in C++11. This fixes some crash-on-invalids where we would allow references to class members in potentially-evaluated constant expressions in static member functions, and also fixes half of PR10177. The fix to PR10177 exposed a case where template instantiation failed to provide a source location for a diagnostic, so TreeTransform has been tweaked to supply source locations when transforming a type. The source location is still not very good, but MarkDeclarationsReferencedInType would need to operate on a TypeLoc to improve it further. Also fix MarkDeclarationReferenced in C++98 mode to trigger instantiation for static data members of class templates which are used in constant expressions. This fixes a link-time problem, but we still incorrectly treat the member as non-constant. The rest of the fix for that issue is blocked on PCH support for early-instantiated static data members, which will be added in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146955 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20Detect when mapping a #include/#import over to a submodule ends upDouglas Gregor
hitting a submodule that was never actually created, e.g., because that header wasn't parsed. In such cases, complain (because the module's umbrella headers don't cover everything) and fall back to including the header. Later, we'll add a warning at module-build time to catch all such cases. However, this fallback is important to eliminate assertions in the ASTWriter when this happens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146933 91177308-0d34-0410-b5e6-96231b3b80d8

redeclaration templates (RedeclarableTemplateDecl), similarly to the way (de-)serialization is implemented for Redeclarable<T>. In the process, found a simpler formulation for handling redeclaration chains and implemented that in both places. The new test establishes that we're building the redeclaration chains properly. However, the FIXME indicates where we're tickling a different bug that has to do with us not setting the DefinitionData pointer properly in redeclarations that we detected after the definition itself was deserialized. The (separable) fix for that bug is forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146883 91177308-0d34-0410-b5e6-96231b3b80d8
