On the 68000 series, use a data reg if possible when the

value is a constant in the range where moveq could be used
|

and we ensure that QImodes are reloaded into data regs.

Also, if a floating constant needs reloading, put it in memory

if possible. */

Also, if a floating constant needs reloading, put it in memory.

Don't do this for !G constants, since all patterns in the md file

expect them to be loaded into a register via fpmovecr. See above. */
