Consolidate Thumb-1/Thumb-2 ISA detection
2015-12-24 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (move_or_literal_pool): Check mov.w, mvm and movw availability against arm_ext_v6t2 instead of checking arm_arch_t2, fixing comments along the way. (handle_it_state): Check arm_ext_v6t2 instead of arm_arch_t2 to generate IT instruction. (t1_isa_t32_only_insn): New function. (md_assemble): Use above new function to check for invalid wide instruction for CPU Thumb ISA and to determine what Thumb extension bit is necessary for that instruction. (md_apply_fix): Use arm_ext_v6t2 instead of arm_arch_t2 to decide if branch is out of range. include/opcode/ * arm.h (ARM_ARCH_THUMB2): Add comment explaining its meaning and remove extension bit not including any Thumb-2 instruction.
