Re: [PATCH, ARM] MSR/MRS assembly and disassembly tweaks

Hi Julian,

     * config/tc-arm.c (parse_psr): Add LHS argument. Improve support
     for *APSR bitmasks.
     (operand_parse_code): Replace OP_PSR with OP_wPSR and OP_rPSR.
     Remove OP_RVC_PSR.
     (parse_operands): Likewise.
     (do_mrs): Tweak error message for constraint.
     (do_t_mrs): Update constraints for changes to APSR support.
     (do_t_msr): Likewise. Don't set PSR_f flag here.
     (psrs): Remove "g", "nzcvq", "nzcvqg".
     (insns): Tweak entries for msr and mrs instructions.

     * arm-dis.c (psr_name): Fix typo for BASEPRI_MAX.
     (print_insn_thumb32): Add APSR bitmask support.

     * gas/arm/mrs-msr-thumb-v7-m.s: New.
