Michal Meloun 6fc9f4dbc8 Preserve VFP state across signal delivery. ... We don't have enouch space to store full VFP context within mcontext stucture. Due to this: - follow i386/amd64 way and store VFP state outside of the mcontext_t but point to it. Use the size of VFP state structure as an 'magic' indicator of the saved VFP state presence. - teach set_mcontext() about this external storage. - for signal delivery, store VFP state to expanded 'struct sigframe'.
