--- Comment #13 from Jeffrey A. Law <law at redhat dot com> ---
I wouldn't lose any sleep if init-regs.c disappeared.

The comment about the ARM ISA being unable to encode certain cases isn't a
strong case in my mind to do something like init-regs.c.  We've dealt with
similar problems in other ports -- you just have to get creative in other ways.
 I can recall dealing with ports that couldn't encode a nop-move for example.
