arm: add armv9-a architecture to -march
Update also include: + New value of Tag_CPU_arch EABI attribute (22) is added. + Updated missing Tag_CPU_arch EABI attributes. + Updated how we combine archs 'v4t_plus_v6_m' as this mechanism have to handle new Armv9 as well. Regression tested on `arm-none-eabi` cross Binutils and no issues. bfd/ * archures.c: Define bfd_mach_arm_9. * bfd-in2.h (bfd_mach_arm_9): Define bfd_mach_arm_9. * cpu-arm.c: Add 'armv9-a' option to -march. * elf32-arm.c (using_thumb2_bl): Update assert check. (arch_has_arm_nop): Add TAG_CPU_ARCH_V9. (bfd_arm_get_mach_from_attributes): Add case for TAG_CPU_ARCH_V9. Update assert. (tag_cpu_arch_combine): Updated table. (v9): New table.. binutils/ * readelf.c (arm_attr_tag_CPU_arch): Update with elfcpp/ * arm.h: Update TAG_CPU_ARCH_ enums with correct values. gas/ * NEWS: Update docs. * config/tc-arm.c (get_aeabi_cpu_arch_from_fset): Return Armv9-a for -amarch=all.
