S/390: Improve support of 128 bit vectors in GPRs
This patch improves the handling of 128 bit vectors residing in GPRs
by adding more alternatives to the move pattern.
Regression tested on s390x.
gcc/ChangeLog:
2017-03-24 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/constraints.md: Add comments.
(jKK): Reject element sizes > 8 bytes.
* config/s390/s390.c (s390_split_ok_p): Enable splitting also for
s_operands.
* config/s390/s390.md: Add the s_operand checks formerly in
s390_split_ok_p to various splitters where they are still
required.
* config/s390/vector.md ("mov<mode>" V_128): Add GPR alternatives
for 128 bit vectors. Plus two splitters.
