S/390: arch13: Add support for new select instruction
Compared to the load on condition instructions we already have the new
select instruction allows to have a THEN and and ELSE source operand -
but only for register to register loads.
gcc/ChangeLog:
2019-04-02 Andreas Krebbel <krebbel@linux.ibm.com>
* config/s390/s390.c (s390_rtx_costs): Do not add extra costs for
if-then-else constructs if we can use the select instruction.
* config/s390/s390.md ("*mov<mode>cc"): Add the new instructions.
gcc/testsuite/ChangeLog:
2019-04-02 Andreas Krebbel <krebbel@linux.ibm.com>
* gcc.target/s390/arch13/sel-1.c: New test.
