1) Issue digsnostics in non-fragile ABI, when an expression evaluates to an interface type (except when it is used to access a non-fragile ivar). 2) Issue unsupported error in fragile ABI when an expression evaluates to an interface type (except when it is used to access a fragile ivar). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80860 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-16Improve the diagnostic emitted when an unused ObjC property getterChris Lattner
is found. Instead of complaining about a generic "unused expr", emit: t.m:7:3: warning: property access result unused - getters should not have side effects While objc property getters *could* have side effects, according to the language best practices, they *shouldn't*. Hopefully the diagnostic now gets this across. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79192 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15Change handling of attribute 'malloc' to only accept the attribute on functionTed Kremenek
declarations (and not function pointers). This is consistent with GCC. Accepting this attribute on function pointers means that the attribute should be treated as a type qualifier, which apparently is not what GCC does. We obviously can change this later should we desire to enhance the 'malloc' attribute in this way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79060 91177308-0d34-0410-b5e6-96231b3b80d8
