S/390: arch13: Support new bit operations
Make use of the new bit operation instructions when generating code
for the arch13 level.
gcc/ChangeLog:
2019-04-02 Andreas Krebbel <krebbel@linux.ibm.com>
* config/s390/s390.c (s390_canonicalize_comparison): Convert
certain compares for arch13 in order to make use of the condition
code result produced by the new instructions.
(s390_rtx_costs): Adjust the costs for nnrk, nngrk, nork, nogrk,
nxrk, and nxgrk instruction patterns.
* config/s390/s390.md (ANDOR, bitops_name, inv_bitops_name)
(inv_no): Add new code iterator together with some attributes.
("*andc_split_<mode>"): Disable splitter for arch13.
("*<ANDOR:bitops_name>c<GPR:mode>_cc")
("*<ANDOR:bitops_name>c<GPR:mode>_cconly")
("*<ANDOR:bitops_name>c<GPR:mode>")
("*n<ANDOR:inv_bitops_name><GPR:mode>_cc")
("*n<ANDOR:inv_bitops_name><mode>_cconly")
("*n<ANDOR:inv_bitops_name><mode>", "*nxor<GPR:mode>_cc")
("*nxor<mode>_cconly", "*nxor<mode>"): New insn definitions.
gcc/testsuite/ChangeLog:
2019-04-02 Andreas Krebbel <krebbel@linux.ibm.com>
* gcc.target/s390/arch13/bitops-1.c: New test.
* gcc.target/s390/arch13/bitops-2.c: New test.
* gcc.target/s390/md/andc-splitter-1.c: Add -march=z14 build
option and adjust line numbers.
* gcc.target/s390/md/andc-splitter-2.c: Likewise.
