This patch is part of a series that adds support for the Armv8.m ARMv8.m Custom Datapath Extension to binutils. This patch introduces the Custom Instructions Class 1/2/3 (Single/ Dual, Accumulator/Non-accumulator varianats) to the arm backend. The following Custom Instructions are added: cx1, cx1a, cx1d, cx1da, cx2, cx2a, cx2d, cx2da, cx3, cx3a, cx3d, cx3da. Specification can be found at https://developer.arm.com/docs/ddi0607/latest This patch distinguishes between enabling CDE for different coprocessor numbers by defining multiple architecture flags. This means that the parsing of the architecture extension flags is kept entirely in the existing code path. We introduce a new IT block state to indicate the behaviour of these instructions. This new state allows being used in an IT block or outside an IT block, but does not allow the instruction to be used inside a VPT block. We need this since the CX*A instruction versions can be used in IT blocks, but they aren't to have the conditional suffixes on them. Hence we need to mark an instruction as allowed in either position. We also need a new flag to objdump, in order to determine whether to disassemble an instruction as CDE related or not. Successfully regression tested on arm-none-eabi, and arm-wince-pe. gas/ChangeLog: 2020-02-10 Stam Markianos-Wright <stam.markianos-wright@arm.com> Matthew Malcomson <matthew.malcomson@arm.com> * config/tc-arm.c (arm_ext_cde*): New feature sets for each CDE coprocessor that can be enabled.
