2012-02-02Split Sema::MarkDeclarationReferenced into multiple functions; the ↵Eli Friedman
additional entry points are needed to implement C++11 odr-use marking correctly. No functional change in this patch; I'll actually make the change which fixes the odr-use marking in a followup patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149586 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-29Complain about attempts to use 'protected' visibility on targetsJohn McCall
like Darwin that don't support it. We should also complain about invalid -fvisibility=protected, but that information doesn't seem to exist at the most appropriate time, so I've left a FIXME behind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149186 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-26Don't suppress access-control or invalid-type diagnostics from aJohn McCall
declarator just because we were able to build an invalid decl for it. The invalid-type diagnostics, in particular, are still useful to know, and may indicate something about why the decl is invalid. Also, recover from an illegal pointer/reference-to-unqualified-retainable type using __strong instead of __autoreleasing; in general, a random object is much more likely to be __strong, so this avoids unnecessary cascading errors in the most common case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149074 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-24The following patch adds __attribute__((no_address_safety_analysis)) which ↵Kostya Serebryany
will allow to disable address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a specific function. When building with AddressSanitizer, add AddressSafety function attribute to every generated function except for those that have __attribute__((no_address_safety_analysis)). With this patch we will be able to 1. disable AddressSanitizer for a particular function 2. disable AddressSanitizer-hostile optimizations (such as some cases of load widening) when AddressSanitizer is on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148842 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-30Add explicit attributes to mark functions as having had theirJohn McCall
CoreFoundation object-transfer properties audited, and add a #pragma to cause them to be automatically applied to functions in a particular span of code. This has to be implemented largely in the preprocessor because of the requirement that the region be entirely contained in a single file; that's hard to impose from the parser without registering for a ton of callbacks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140846 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Add an ns_bridged attribute, used to specify that a John McCall
pointer to the annotated struct type can be used as an Objective-C object pointer. If an argument is given, the type is actually "toll-free bridged" to the specific type named there, rather than just to 'id'. For now, we cannot rely on all types being so annotated, and we'll always have to have exceptions for things like CFTypeRef (aka const void*), but this is clearly a good foundation for improving toolage in this area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140779 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-09Clean up the sentinel-attribute checking code a lot. DocumentJohn McCall
what 'nullPos' is supposed to mean, at least at this one site. Use closed forms for the arithmetic. Rip out some clever but ultimately pointless code that was trying to use 0 or 0L depending the size of a pointer vs. the size of int; first, it didn't work on LLP64 systems, and second, the sentinel checking code requires a pointer-typed value anyway, so this fixit would not have actually removed the warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139361 91177308-0d34-0410-b5e6-96231b3b80d8
