Rename diagnostic to reflect it's role...

It is allowed to get the address of an array subscript, even if the array has the register qualifier, if the array is really a pointer.

Fix Sema::ActOnInstanceMessage to correctly do things in terms of canonical 
types, fixing bogus errors like:

NSDistantObject.m:10383:120: error: bad receiver type 'typeof((id<NSMutableCopying>)self)'
    id mess = ({ id __inv__ = ((void *)0); id __mb__ = _NSMessageBuilder((id <NSMutableCopying>)self, &__inv__); (void)[(__typeof__((id <NSMutableCopying>)self))__mb__ mutableCopyWithZone:((void *)0)]; if (!objc_collecting_enabled()) object_dispose(__mb__); __inv__; });

here I fix just one.  The loop that rips through pointers should use
getAsPointerType() not static_cast<PointerType*> to get the pointee.  This
fixes a crash on a large testcase.

Hack Sema::MergeTypeDefDecl() to silently ignore duplicate typedef's in system headers files.

A bizarre, non-standard hook that many compilers appear to implement (sigh:-).

that causes this isn't really correct, but if we're going to accept 
this, it should come up with a consistent AST.

llvm-svn: 46557

Many refinements to Sema::MergeVarDecl(). This routine still needs some re-work to fully handle tentative decls.

This includes a fix to bz1908.

Rewriting of @synchronized. This has one FIXME in it. But this should allow @sychronized to be rewritten.

Tighten up ASTContext::typesAreCompatible()...it needs to make sure the qualifiers match. The comment and C99 citation for this routine were correct...the code needed to conform to the comment/spec. This fixes the test added below.

Tightening up this routine forced tweaks to Sema::CheckSubtractionOperands() and Sema::CheckCompareOperands(). For example, they both need to operate on the unqualified pointee...

llvm-svn: 46522

doesn't get confused by typedefs.

llvm-svn: 46502

Tweak Sema::DefaultArgumentPromotion() to call UsualUnaryConversions(). This makes sure function calls that don't have a prototype get the default function/array conversion.

Patch by Eli Friedman!

Implement "private extern" on function decls!

llvm-svn: 46464

Fix a bug with struct initializers (in Sema::CheckInitializerListTypes()). 
Test case included from bz1948 (thanks Neil!).
Also fixed an 80 column violation...

llvm-svn: 46430

Add more support for Apple's "private extern" extension...

llvm-svn: 46371

llvm-svn: 46358

Replace Sema::CheckVariableInitList, CheckConstantInitList, and CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers.

This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-)

Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-)

Sema::FinalizeDeclaratorGroup(): Tighten up the tentative definition rule when dealing with arrays.

Bug submitted by Eli.

llvm-svn: 46179

Sema::FinalizeDeclaratorGroup()...make sure we emit an diagnostic for tentative definitions with incomplete types. Touch up all test cases that are effected.

__builtin_overload takes 2 or more arguments:
0) a non-zero constant-expr for the number of arguments the overloaded 
   functions will take
1) the arguments to pass to the matching overloaded function
2) a list of functions to match.

The return type of __builtin_overload is inferred from the function whose args
match the types of the arguments passed to the builtin.  For example:

float a;
float sinf(float);
int   sini(int);

float b = __builtin_overload(1, a, sini, sinf);

Says that we are overloading functions that take one argument, and trying to 
pass an argument of the same type as 'a'.  sini() does not match since it takes
and argument of type int.  sinf does match, so at codegen time this will turn
into float b = sinf(a);

size in accordance with how rewriter synthesizes method name.

Refactored the use of this method into both the Sema module and Analysis module,
which were using their own static functions that did the same thing.
