This patch is part of the patch series to add support for ARMv8.5-A extensions. (https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order) This patch adds the prediction restriction instructions (that is, cfp, dvp, cpp). These instructions are retrospectively made optional for all versions of the architecture from ARMv8.0 to ARMv8.4 and is mandatory from ARMv8.5. Hence adding a new +predres which can be used by the older architectures. *** include/ChangeLog *** 2018-10-09 Sudakshina Das <sudi.das@arm.com> * opcode/aarch64.h (AARCH64_FEATURE_PREDRES): New. (AARCH64_ARCH_V8_5): Add AARCH64_FEATURE_PREDRES by default. (aarch64_opnd): Add AARCH64_OPND_SYSREG_SR. (aarch64_sys_regs_sr): Declare new table. *** opcodes/ChangeLog *** 2018-10-09 Sudakshina Das <sudi.das@arm.com> * aarch64-dis.c (aarch64_ext_sysins_op): Add case for AARCH64_OPND_SYSREG_SR. * aarch64-opc.c (aarch64_print_operand): Likewise. (aarch64_sys_regs_sr): Define table. (aarch64_sys_ins_reg_supported_p): Check for RCTX with AARCH64_FEATURE_PREDRES. * aarch64-tbl.h (aarch64_feature_predres): New. (PREDRES, PREDRES_INSN): New. (aarch64_opcode_table): Add entries for cfp, dvp and cpp. (AARCH64_OPERANDS): Add new description for SYSREG_SR. * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Regenerate. * aarch64-opc-2.c: Regenerate. *** gas/ChangeLog *** 2018-10-09 Sudakshina Das <sudi.das@arm.com> * config/tc-aarch64.c (aarch64_sys_regs_sr_hsh): New. (parse_operands): Add entry for AARCH64_OPND_SYSREG_SR. (md_begin): Allocate and initialize aarch64_sys_regs_sr_hsh with aarch64_sys_regs_sr. (aarch64_features): Add new "predres" option for older architectures. * doc/c-aarch64.texi: Document the same. * testsuite/gas/aarch64/sysreg-4.s: New. * testsuite/gas/aarch64/sysreg-4.d: New. * testsuite/gas/aarch64/illegal-sysreg-4.d: New. * testsuite/gas/aarch64/illegal-sysreg-4.l: New. * testsuite/gas/aarch64/predres.s: New. * testsuite/gas/aarch64/predres.d: New. |
