- Subject: PATCH Define object header bits for VFP variant assembly
- Organization: ARM Ltd.
- Reply-to: Richard dot Earnshaw at arm dot com
The attached patch defines some bits for use in header files to indicate
that a file has VFP instructions in it. This will be used by future
patches to ensure object file compatibility during linking.
