The patch is straightforward, it does the following: - support the new Tag_CPU_arch build attribute value, ie.: + declare the new value + update all the asserts forcing logic to be reviewed for new architectures + create a corresponding bfd_mach_arm_8_1M_MAIN enumerator in bfd and add mapping from Tag_CPU_arch to it + teach readelf about new Tag_CPU_arch value - declare armv8.1-m.main as a supported architecture value - define Armv8.1-M Mainline in terms of feature bits available - tell objdump mapping from bfd_mach_arm_8_1M_MAIN enumerator to feature bits available - update architecture-specific logic in gas and bfd guarded by the asserts mentioned above. - tests for all the above ChangeLog entries are as follows: *** bfd/ChangeLog *** 2019-04-15 Thomas Preud'homme <thomas.preudhomme@arm.com> * archures.c (bfd_mach_arm_8_1M_MAIN): Define. * bfd-in2.h: Regenerate. * cpu-arm.c (arch_info_struct): Add entry for Armv8.1-M Mainline. * elf32-arm.c (using_thumb_only): Return true for Armv8.1-M Mainline and update assert.
