+
+ * config/bfin/bfin-opts.h: New.
+ * config/bfin/bfin.c (bfin_lib_id_given, bfin_cpu_type,
+ bfin_si_revision, bfin_workarounds): Remove.
+ (bfin_cpus): Make static const.
+ (bfin_load_pic_reg): Check global_options_set.x_bfin_library_id
+ not bfin_lib_id_given.
+ (bfin_handle_option): Don't set bfin_lib_id_given. Access
+ bfin_cpu_type, bfin_si_revision and bfin_workarounds via opts
+ pointer. Use error_at. Don't assert that global structures are in
+ use.
+ * config/bfin/bfin.h: Include bfin-opts.h.
+ (enum bfin_cpu_type, bfin_cpu_t): Move to bfin-opts.h.
+ (bfin_cpu_type, bfin_si_revision, bfin_workarounds): Remove.
+ * bfin.opt (config/bfin/bfin-opts.h): New HeaderInclude entry.
+ (bfin_cpu_type, bfin_si_revision, bfin_workarounds): New Variable
+ entries.
