Patch by Zhongxing Xu!

llvm-svn: 53976

 - Also cleaned up emission slightly 
 - Inspection of the code revealed several other bugs, however. Case
   ranges are not properly wired and can result in switch cases being
   dropped or even infinite loops. See: <rdar://problem/6098585>

 - For getting an APSInt from a known integer constant Expr.
 - TODO: Many users of Expr::isIntegerConstantExpr in codegen should
   probably be using this instead...

Refine the error message of unused ivars.
Added test case.

llvm-svn: 53956

When constructing an ObjCIvarDecl object in Sema, provide its visibility up front instead of setting it afterwards.
This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

is protected, not private.

Added ObjCIvarDecl::getCanonicalAccessControl() to report the visible access
control of an ivar, whereas getAccessControl() returns the access control
relating to how the ivar was actually declared.

This implements <rdar://problem/6069935>

This subsumes Nico Weber's patch and implements bzero in terms
of llvm.memset to match llvm-gcc.

This closes <rdar://problem/6080720>, support for __builtin_constant_p
has been filed separately.

of a specific smallvector size.

Fix protocol lists to pass down proper location info, so we get diagnostics
like this:

t.m:3:35: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^


Add a new IdentifierLocPair typedef which is just a pair<IdentifierInfo*, SourceLocation>
