* Makefile.in (toplev.o): Depend on params.h. (intergate.o): Likewise. (params.o): New target. * flags.h (inline_max_insns): Remove. * integrate.c: Include params.h. Use MAX_INLINE_INSNS instead of inline_max_insns. * params.c: New file. * params.h: Likewise. * params.def: Likewise. * toplev.c: Include params.h. (lang_independent_params): New variable. (decode_f_option): Use the param machinery instead of setting max_inline_insns. (independent_decode_option): Handle "--param name=value". (main): Register language-independent parameters.
