It also leads to reading past the end of the section. This patch tidies that by reading the proper field size, which allows some later refetching of addends to disappear. PR 26422 * elf32-arm.c (elf32_arm_final_link_relocate): Use the appropriate bfd_get_x size function to read addends out of fields. Apply rightshift adjustment too. Don't apply the now unnecessary howto->size shift to branch REL addends. Don't refetch R_ARM_ABS8 and R_ARM_ABS16 addends. Don't refetch thumb branch addends. Correct R_ARM_THM_JUMP6 addend. -- You are receiving this mail because: You are on the CC list for the bug.
