We were comparing a mode size with word_mode, but word_mode is an enum value thus this does not really make any sense. (Un)luckily E_DImode happens to be 8 so this seemed to work, but let's make it correct so it won't blow up when we add LA32 support or add another machine mode...
gcc/ChangeLog: * config/loongarch/loongarch.cc (loongarch_expand_conditional_move): Compare mode size with UNITS_PER_WORD instead of word_mode. --- I've not fully tested this but it should be obvious.
