X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bef8d8c781b86b91ff52d5f99e5d6bfa8ea19fdf;p=gcc.git

(cpu_type, sparc_cpu_type): Rename to arch_type and sparc_arch_type.

(cpu_type, sparc_cpu_type): Rename to arch_type and
sparc_arch_type.
(CPP_SPEC): Handle -msupersparc.
(MASK_SUPERSPARC, TARGET_SUPERSPARC): New macros.
