From 8b301fbb6114faba4e95e24e3a1c3108f64885c6 Mon Sep 17 00:00:00 2001 From: Mihail Ionescu Date: Fri, 22 Nov 2019 13:44:17 +0000 Subject: [PATCH] Arm: Change CRC from fpu feature to archititectural extension This patch changes the CRC extension to use the core feature bits instead of the coproc/fpu feature bits. CRC is not an fpu feature and it causes issues with the new fpu reset patch (f439988037a589de3798f44e7268301adaec21a9). CRC can be set using the '.arch_extension' directive, which sets bits in the coproc bitfield. When a '.fpu' directive is encountered, the CRC feature bit gets removed and there is no way to set it back using '.fpu'. With this patch, CRC will be marked in the feature core bits, which prevents it from getting removed when setting/changing the fpu options. gas/ChangeLog: * config/tc-arm.c (arm_ext_crc): New. (crc_ext_armv8): Remove. (insns): Rename crc_ext_armv8 to arm_ext_crc. (arm_cpus): Replace CRC_EXT_ARMV8 with ARM_EXT2_CRC. (armv8a_ext_table, armv8r_ext_table, arm_option_extension_value_table): Redefine the crc extension in terms of ARM_EXT2_CRC. * gas/testsuite/gas/arm/crc-ext.s: New. * gas/testsuite/gas/arm/crc-ext.d: New. include/ChangeLog: * opcode/arm.h (ARM_EXT2_CRC): New extension feature to replace CRC_EXT_ARMV8.
