2012-07-19For varargs, diagnose passing ObjC objects by value like other non-POD types.Jordan Rose
While we still want to consider this a hard error (non-POD variadic args are normally a DefaultError warning), delaying the diagnostic allows us to give better error messages, which also match the usual non-POD errors more closely. In addition, this change improves the diagnostic messages for format string argument type mismatches by passing down the type of the callee, so we can say "variadic method" or "variadic function" appropriately. <rdar://problem/11825593> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160517 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-19Don't crash checking a format string if one of the arguments is invalid.Jordan Rose
Previously, we would ask for the SourceLocation of an argument even if it were NULL (i.e. if Sema resulted in an ExprError trying to build it). <rdar://problem/11890818> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160515 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-19Force the OS X version to 10.6 for old-style simulator builds.Bob Wilson
The hack of recognizing a -D__IPHONE_OS_VERSION_MIN_REQUIRED option in place of -mios-simulator-version-min leaves the Darwin version unspecified. It can be set separately with -mmacosx-version-min (which makes no sense) or inferred to match the host version (which is unpredictable and usually wrong). This really needs to get cleaned up, but in the meantime, force the OS X version to 10.6 so that the behavior is sane for the iOS simulator. Thanks for Argyrios for the patch. <rdar://problem/11858187> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160484 91177308-0d34-0410-b5e6-96231b3b80d8

Panzer. I've not been able to trigger a failure caused by this, so no test yet.

it solves them). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160462 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Combine all ObjC message CallEvents into ObjCMethodCall.Jordan Rose
As pointed out by Anna, we only differentiate between explicit message sends This also adds support for ObjCSubscriptExprs, which are basically the same as properties in many ways. We were already checking these, but not emitting nice messages for them. This depends on the llvm::PointerIntPair change in r160456. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160461 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Rename addExtraInvalidatedRegions to get...RegionsJordan Rose
Per Anna's comment that "add..." sounds like a method that modifies the receiver, rather than its argument. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160460 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Make CallEvent a value object.Jordan Rose
We will need to be able to easily reconstruct a CallEvent from an ExplodedNode for diagnostic purposes, and that's exactly what factory functions are for. CallEvent objects are small enough (four pointers and a SourceLocation) that returning them through the stack is fairly cheap. Clients who just need to use existing CallEvents can continue to do so using const references. This uses the same sort of "kind-field-dispatch" as SVal, though most of the nastiness is contained in the DISPATCH and DISPATCH_ARG macros at the end of the file. (We can't use a template for this because member-pointers to base class methods don't call derived-class methods even when casting to the derived class. We can't use variadic macros because they're a C99 feature.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160459 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Remove obsolete ObjCPropRef SVal kind.Jordan Rose
ObjC properties are handled through their semantic form of ObjCMessageExprs and their wrapper PseudoObjectExprs, and have been for quite a while. The syntactic ObjCPropertyRefExprs do not appear in the CFG and are not visited by ExprEngine. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160458 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-18Remove trivial destructor from SVal.Benjamin Kramer
This enables the faster SmallVector in clang and also allows clang's unused variable warnings to be more effective. Fix the two instances that popped up.

and a function template instantiation, if there's a parameter pack in the declaration and one at the same place in the instantiation, don't assume that the pack wasn't expanded -- it may have expanded to nothing.
