2008-05-28 Andreas Krebbel <krebbel1@de.ibm.com> * 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. From-SVN: r136097
