--- Comment #1 from Dimitar Dimitrov <dimitar at gcc dot gnu.org> --- I explored setting REGMODE_NATURAL_SIZE=4 for PRU. This required adjustments in many places in middle end to use REGMODE_NATURAL_SIZE instead of word_mode. That however proved too intrusive. And I don't see how other targets would benefit. I'll instead go with defining an expansion of cbranchdi4 for PRU. That would be contained in the PRU backend only, and thus safer.
