[binutils, ARM, 12/16] Scalar Low Overhead loop instructions for Armv8.1-M Mainline
s patch is part of a series of patches to add support for Armv8.1-M Mainline instructions to binutils.
This patch adds support to the Scalar low overhead loop instructions:
LE
WLS
DLS
We also add a new assembler resolvable relocation bfd_reloc_code_real enum for the 12-bit branch offset used in these instructions.
ChangeLog entries are as follows:
