* config/s390/s390.c (z10_cost): New cost function for z10. (s390_handle_arch_option, override_options): Support -march=z10 switch. (s390_issue_rate): Adjust issue rate for z10. * config/s390/s390.h (processor_type): Add PROCESSOR_2097_Z10. (processor_flags): Add PF_Z10. (TARGET_CPU_Z10, TARGET_Z10): New macro definitions. * config/s390/s390.md (cpu, cpu_facility attributes): Add z10. * gcc/config.gcc: Add z10. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@136097 138bc75d-0d04-0410-961f-82ee72b054a4
