member access in the presense of non-virtual bases.

Use the CGRecordLayoutBuilder even if there are no fields, because in C++ an empty class will have a padding byte.

llvm-svn: 77205

Enable the new struct type builder now that the constant struct builder works. (The old code will still be there until we know that everything works well.

llvm-svn: 77190

llvm-svn: 77189

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: 77087

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.

 - Steve, can you take a look at this? It seems like this code should live
   elsewhere, and there is a FIXME about having Sema validates the UTF-8 to
   UTF-16 conversion.

We don't need to keep track of the packed alignment, just whether the struct is packed or not. Fixes PR4610.

llvm-svn: 76884

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

Use arrays as union padding. Also, since the resulting struct will always contain a single element and either a single i8 element or an array of i8s, there's no reason to use a packed struct.

Check in  CGRecordLayoutBuilder which is a reimplementation of the record layout code. (Yay, no more packed structs unless absolutely necessary). We currently don't use the layouts being built but that will change when the new code is mature enough :)

llvm-svn: 76845

Technically we could still do a bit more to avoid deferred generation of statics
which we know are used, but I seriously doubt this is important.

llvm-svn: 76844

This requires llvm rev. 76769 or higher.

llvm-svn: 76770

Fix a couple recent ABI regressions noticed during code review (fallout from the ObjC type system rewrite).

It's unfortunate that the mangling includes the low-level structs. Nevertheless, we need this for binary compatibility with GCC.
