From e2b0ab597857bfe9d7c8742ff50bbb77c70936c4 Mon Sep 17 00:00:00 2001 From: Andre Vieira Date: Mon, 15 Apr 2019 11:12:57 +0100 Subject: [PATCH] [binutils, ARM, 4/16] BF insns infrastructure with array of relocs in struct arm_it 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 Branch Future instructions (BF, BFX, BFL, BFLX, BFCSEL). These are the first instructions in ARM that have more than one relocations in them. Their external relocations can be found in the 'ELF for the Arm Architecture - ABI 2019Q1' document on developer.arm.com This is the second infrastructure patch that adds support to allow up to 3 relocations in an instruction. This is done by changing the reloc member of struct arm_it to an array instead (relocs[3]). All the previous occurrences of reloc can now to referring to relocs[0]. ChangeLog entries are as follows : *** gas/ChangeLog *** 2019-04-15 Sudakshina Das * config/tc-arm.c (ARM_IT_MAX_RELOCS): New macro. (arm_it): Member reloc renamed relocs and updated to an array.
