* MS ABI: Consider alignment attributes on typedefs for layoutDavid Majnemer2014-07-301-2/+13
| | | | | | | | | | | | | | | | | | | The MS ABI has a notion of 'required alignment' for fields; this alignment supercedes pragma pack directives. MSVC takes into account alignment attributes on typedefs when determining whether or not a field has a certain required alignment. Do the same in clang by tracking whether or not we saw such an attribute when calculating the type's bitwidth and alignment. This fixes PR20418.

* Hide the concept of diagnostic levels from lex, parse and semaAlp Toker2014-06-151-9/+5
| | | | | | | | | | | | | | | | The compilation pipeline doesn't actually need to know about the high-level concept of diagnostic mappings, and hiding the final computed level presents several simplifications and other potential benefits. The only exceptions are opportunistic checks to see whether expensive code paths can be avoided for diagnostics that are guaranteed to be ignored at a certain SourceLocation. This commit formalizes that invariant by introducing and using DiagnosticsEngine::isIgnored() in place of individual level checks throughout lex, parse and sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211005 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | inherited protocols and protocols already conformed in the class hierarchy. Per more discussion, 'objc_protocol_requires_explicit_implementation' is refinement that it mainly adds that requirement that a protocol must be explicitly satisfied at the moment the first class in the class hierarchy conforms to it. Any subclasses that also conform to that protocol, either directly or via conforming to a protocol that inherits that protocol, do not need to re-implement that protocol. Doing this requires first doing a pass on the super class hierarchy, gathering the set of protocols conformed to by the super classes, and then culling those out when determining conformance. This two-pass algorithm could be generalized for all protocol checking, and could possibly be a performance win in some cases. For now we restrict this change to protocols with this attribute to isolate the change in logic (especially as the design continues to evolve). This change needs to be adjusted for properties as well; this only impacts methods right now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202948 91177308-0d34-0410-b5e6-96231b3b80d8
