S/390: Enable vrepi constants.
gcc/testsuite/ChangeLog:
2015-12-02 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* gcc.target/s390/vector/vec-vrepi-1.c: New test.
gcc/ChangeLog:
2015-12-02 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/constraints.md ("jKK"): New constraint.
* config/s390/s390.c (tm-constrs.h): Include for
satisfies_constraint_*.
(s390_legitimate_constant_p): Allow jKK constants. Use
satisfies_constraint_* also for the others.
(legitimate_reload_vector_constant_p): Likewise.
(print_operand): Allow h output modifier on vectors.
* config/s390/vector.md ("mov<mode>"): Add vrepi.
