PR29390, DW_CFA_AARCH64_negate_ra_state vs. DW_CFA_GNU_window_save
PR 29390 binutils/ * dwarf.c (is_aarch64, DW_CFA_GNU_window_save_name): New. (display_debug_frames): Use them. (init_dwarf_regnames_aarch64): Set is_aarch64. (init_dwarf_regnames_by_elf_machine_code): Clear is_aarch64. (init_dwarf_regnames_by_bfd_arch_and_mach): Likewise. gas/ * testsuite/gas/aarch64/pac_ab_key.d: Adjust expected output. * testsuite/gas/aarch64/pac_negate_ra_state.d: Likewise.
