    • (arm_select): Declare and initialize. · bd9c7e23 
      (all_procs): Add arm7100.
(arm_override_options): Parse arm_select structure to determine selected
architecture and tuning parameters.
(output_option, output_options): New functions.
(arm_canonicalize_comparison): New function.
(arm_gen_movstrqi): Don't add a writeback of the index registers for the
last instructions.
(arm_select_cc_mode): Detect case where mode is carry out of unsigned
arithmetic.
(output_lcomm_directive): Use bss_section (), and use alignment rather than
rounding.
(get_arm_condition_code): Handle CC_Cmode.
(final_prescan_insn): Avoid boundary case where we would occasionally
inline MAX_INSNS_SKIPPED+1 insns.  Allow call_insns to be inlined in APCS_32
mode if they are the last insn in the block.

independent of the selected assembler, and to use optimal number of
instructions.

        (andqi3 expander): Remove constrains.
        (andhi3): Don't underestimate length.
        (andsi3): Don't underestimate length.  Improve code when upper
        or lower half of destination is being cleared.
        (indirect_jump_h8300, indirect_jump_h8300h): Simplify.
        (shift insns): Remove useless "I" constraint.
