[binutils, ARM, 1/16] Add support for Armv8.1-M Mainline CLI
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:
