Improve handling of member pointers.

llvm-svn: 78536

Fix clang breakage, CGF can be null in this context.

llvm-svn: 78269

Update for LLVM API change.

llvm-svn: 78259

use CodeGenModule::EmitNullConstant in a couple of places.

llvm-svn: 77915

Fix a minor issue with unions in the new struct building code.

llvm-svn: 77829

Remove the old struct builder code.

llvm-svn: 77738

Move code from EmitUnion directly into the function that handles cast-to-union.

llvm-svn: 77735

Use the struct builder for unions.

llvm-svn: 77732

Update for LLVM API change.

llvm-svn: 77722

Update for LLVM API change.

llvm-svn: 77514

Change uses of:
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
Type::getAsRecordType() -> Type::getAs<RecordType>()
Type::getAsPointerType() -> Type::getAs<PointerType>()
Type::ge

Change uses of:
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
Type::getAsRecordType() -> Type::getAs<RecordType>()
Type::getAsPointerType() -> Type::getAs<PointerType>()
Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
Type::getAsTagType() -> Type::getAs<TagType>()

And remove Type::getAsReferenceType(), etc.

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.

Enable the new constant struct builder by default. The old code is still in place but will be removed shortly. The new struct builder works on big endian systems.

llvm-svn: 77185

More work on the constant struct builder, fix a couple of thinkos and add support for inserting part of a bitfield in the previous byte.

llvm-svn: 77180

More work on bitfield support in the new constant struct builder.

llvm-svn: 77177

More work on the constant struct builder. We can now convert the struct to a packed struct when necessary.

llvm-svn: 77038

More work on the constant struct builder. We now try to layout all constant structs but throw away the result.

Move the LLVM field number for bit fields into the BitFieldInfo structure, since it's meaning is completely different than for non-bit fields.
