value-dependent. Audit (and fixed) all calls to
Expr::isNullPointerConstant() to provide the correct behavior with
value-dependent expressions. Fixes PR5041 and a crash in libstdc++
<locale>.
In the same vein, properly compute value- and type-dependence for
ChooseExpr. Fixes PR4996.

Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right; many more remain.
llvm-svn: 82705
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely. Several more 'leaf'
optimizations were introduced.
The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

integral constant expressions (for conversions to integer types,
naturally). I don't *think* that const_casts will ever get to this
point, but I also can't convince myself that they won't... so I've
taken the safe route and allowed the ICE checking code to look at
const_cast.

source range. We'll do the same thing with explicitly-specified
template arguments, assuming I don't flip-flop again.

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.
When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

Fixes PR4704 problems
Addresses Eli's patch feedback re: ugly cast code
Updates all postfix operators to remove ParenListExprs. While this is awful,
no better solution (say, in the parser) is obvious to me. Better solutions
welcome.

In addition to being defined by the AltiVec PIM, this is also the vector
initializer syntax used by OpenCL, so that vector literals are compatible
with macro arguments.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

Enhance test case to cover 'isa' access on interface types (clang produces an error, GCC produces a warning).
Still need back-end CodeGen for ObjCIsaExpr.

until Doug Gregor's Type smart pointer code lands (or more discussion occurs).
These methods just call the new Type::getAs<XXX> methods, so we still have
reduced implementation redundancy. Having explicit getAsXXXType() methods makes
it easier to set breakpoints in the debugger.
llvm-svn: 76193
This method is intended to eventually replace the individual
Type::getAsXXXType<> methods.
The motivation behind this change is twofold:
1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of
them are basically copy-and-paste.
2) By centralizing the implementation of the getAs<Type> logic we can more
smoothly move over to Doug Gregor's proposed canonical type smart pointer
scheme.
Along with this patch:
a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>.
b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>.
