[Arm, 3/3] Add Execution and Data Prediction instructions for AArch32
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/exploration-tools) This patch adds the Execution and Data Prediction Restriction instructions (that is, cfprctx, dvprxtc, cpprctx). These are all aliases to MCR and are disassembled as such. This instruction is 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 for older versions of the architecture. *** include/ChangeLog *** 2018-10-05 Sudakshina Das <sudi.das@arm.com> * opcode/arm.h (ARM_EXT2_PREDRES): New. (ARM_ARCH_V8_5A): Add ARM_EXT2_PREDRES by default. *** gas/ChangeLog *** 2018-10-05 Sudakshina Das <sudi.das@arm.com> * config/tc-arm.c (arm_ext_predres): New. (insns): Add new cfprctx, dvprctx and cpprctx instructions. (arm_extensions): Add "predres". * doc/c-arm.texi: Document the above. * testsuite/gas/arm/predres-bad.d: New test. * testsuite/gas/arm/predres-bad.l: New test. * testsuite/gas/arm/predres.s: New test. * testsuite/gas/arm/predres1.d: New test. * testsuite/gas/arm/predres2.d: New test.
