Log:
Generate PADDI (PLI) to load up 32-bit SImode constants when -mcpu=future is done.
2019-11-27 Michael Meissner <meissner@linux.ibm.com>
* config/rs6000/rs6000.md (movsi_internal): Add alternative to
use PADDI (PLI) to load up 32-bit constants when -mcpu=future is
used.
(movsi splitter): Don't split load of SImode constant if it can be
done in a single instruction.
