re PR target/81593 (Optimize PowerPC vector set from vector extract)
[gcc]
2017-08-07 Michael Meissner <meissner@linux.vnet.ibm.com>
PR target/81593
* config/rs6000/vsx.md (vsx_concat_<mode>, VSX_D): Cleanup
constraints since the -mupper-regs-* switches have been
eliminated.
(vsx_concat_<mode>_1): New combiner insns to recognize inserting
into a vector from a double word element that was extracted from
another vector, and eliminate extra XXPERMDI instructions.
(vsx_concat_<mode>_2): Likewise.
(vsx_concat_<mode>_3): Likewise.
(vsx_set_<mode>, VSX_D): Rewrite vector set in terms of vector
concat to allow optimizing inserts from previous extracts.
