space better. Remove this reference. To make that work, change some APIs
(most importantly, getDesugaredType()) to take an ASTContext& if they
need to return a QualType. Simultaneously, diminish the need to return a
QualType by introducing some useful APIs on SplitQualType, which is
just a std::pair<const Type *, Qualifiers>.

visibility. Fixes PR8713.
I've disabled a test which was testing that you can #pragma pop visibility
to get out of a namespace's visibility attribute. We should probably just
diagnose that as an error unless it's instrumental to someone's system
headers.
llvm-svn: 121459
global code completions are disabled (e.g., because they are
cached). Also, make sure that forward-declared protocols are visited
when we look for all visible names within a declaration context.
Previously, we would end up with duplicate completions for protocols.
llvm-svn: 121416
declaration that is a value in ill-formed code. Instead of crashing,
treat this as a dependent typename specifier and suggest that the
using add "typename" into the using declaration. Fixes <rdar://problem/8740998>.

zextOrTrunc(), and APSInt methods extend(), extOrTrunc() and new method
trunc(), to be const and to return a new value instead of modifying the
object in place.

cv-qualification conversions. More specifically, there's an implicit
cv-qualification conversion (even one that drops qualifiers) when
converting to 'id' or qualified 'id'. Fixes <rdar://problem/8734046>.
llvm-svn: 121047
FunctionArrayLvalueConversion but without the function/array decay. Generally
this is only appropriate for use sites that know the type of the expression
and thus that it can't be subject to the decays.
Also make sure we do lvalue-to-rvalue on the bases of ivar references.
llvm-svn: 121035
so that's not a valid thing to do at all. Instead, switch to a ValueDecl
argument, the template isn't really necessary here.
When handling the types explicitly in the code, it becomes awkward to cerate
the CXXBaseOrMemberInitializer object in so many places. Re-flow the code to
calculate the Init expression first, and then create the initializer. If this
is too gross, we can factor the init expression logic into helper functions,
but it's not past my threshold yet.
llvm-svn: 120997
build one when either of the operands calls itself type-dependent;
previously we were building when one of the operand types was dependent,
which is not always the same thing and which can lead to unfortunate
inconsistencies later. Fixes PR8739.
llvm-svn: 120990
struct X {
X() : au_i1(123) {}
union {
int au_i1;
float au_f1;
};
};
clang will now deal with au_i1 explicitly as an IndirectFieldDecl.
llvm-svn: 120900
not actually frequently used, because ImpCastExprToType only creates a node
if the types differ. So explicitly create an ICE in the lvalue-to-rvalue
conversion code in DefaultFunctionArrayLvalueConversion() as well as several
other new places, and consistently deal with the consequences throughout the
compiler.
In addition, introduce a new cast kind for loading an ObjCProperty l-value,
and make sure we emit those nodes whenever an ObjCProperty l-value appears
that's not on the LHS of an assignment operator.
This breaks a couple of rewriter tests, which I've x-failed until future
development occurs on the rewriter.
Ted Kremenek kindly contributed the analyzer workarounds in this patch.

about deprecated Objective-C pointer conversions. Plus, make sure to
actually set an appropriate AssignmentAction when performing an
implicit conversion from an InitializationSequence. Fixes regressions
in the GCC DejaGNU testsuite.
llvm-svn: 120744
Check for compatible gcc, Altivec and Neon vectors before handling the
lax-vector-conversions case. Otherwise there is no way to avoid the
warnings from -Wvector-conversions.
llvm-svn: 120633
conversions. Previously, we would end up collapsing qualification
conversions into the Objective-C pointer conversion step, including
(possibly) stripping qualifiers that shouldn't be removed.
This generalizes BuildSimilarlyQualifiedPointerType() to also work on
Objective-C object pointers, then eliminates the (redundant, not
totally correct) BuildSimilarlyQualifiedObjCObjectPointerType()
function.
Fixes <rdar://problem/8714395>.
