[binutils, ARM, 8/16] BFL infrastructure with new global reloc R_ARM_THM_BF18
This patch is part of a series of patches to add support for Armv8.1-M Mainline instructions to binutils. This adds infrastructure for the BFL instructions which is one of the first instructions in Arm that have more than one relocations in them. This adds a new relocation R_ARM_THM_BF18. The inconsistency between external R_ARM_THM_BF18 and internal BFD_RELOC_ARM_THUMB_BF19 is because internally we count the static bit-0 of the immediate and we don't externally. ChangeLog entries are as follows : *** bfd/ChangeLog *** 2019-04-15 Sudakshina Das <sudi.das@arm.com> * reloc.c (BFD_RELOC_ARM_THUMB_BF19): New * libbfd.h: Regenerated. * bfd-in2.h: Regenerated. * bfd-elf32-arm.c (elf32_arm_howto_table_1): New entry for R_ARM_THM_BF18.
