Re: Avoid global state in rx_handle_option

[Nick Clifton]

Hi Joseph,

Tested building cc1 and xgcc for cross to rx-elf.  Will commit to
trunk in the absence of target maintainer objections.

2011-04-04  Joseph Myers<jos...@codesourcery.com>

        * config/rx/rx-opts.h: New.
        * config/rx/rx.c (rx_cpu_type): Remove.
        (rx_handle_option): Don't assert that global structures are in
        use.  Access variables via opts pointer.  Defer most handling of
        OPT_mint_register_.  Use error_at.
        (rx_option_override): Handle deferred OPT_mint_register_ here.
        * config/rx/rx.h (enum rx_cpu_types): Move to rx-opts.h.
        * config/rx/rx.opt (config/rx/rx-opts.h: New HeaderInclude.
        (mcpu=): Use Enum and specifiy rx_cpu_type with Var.
        (rx_cpu_types): New Enum and EnumValue entries.
        (mint-register=): Use Defer and use Var accordingly.

No objections - please apply.

Cheers
  Nick
