sh-elf build failure on i686-linux

[Toshiyasu Morita <tm at netcom dot com>]

      version: CVS today
         host: i386-linux (Red Hat 6.1)
       target: sh-elf
host compiler: gcc-2.7.2.3

I've been getting a build failure for the past two days now. It looks
like gcc is trying to move a value from a floating-point register
to an integer register directly without going through fpul.

Maybe REGISTER_MOVE_COST needs to be tweaked?
