This patch finally adds support for the LEON family of processors to the SPARC back-end. It also removes some left-overs (sparc86x and old Solaris stuff). This is mostly Konrad et al.'s work, with some bits coming from AdaCore. Applied on the mainline. I'll add a blurb to the CHANGES file later. 2010-12-16 Konrad Eisele <konrad@gaisler.com> Eric Botcazou <ebotcazou@adacore.com> Support for LEON processor * config.gcc (sparc-*-elf*): Deal with sparc-leon specifically. (sparc-*-linux*): Likewise. (sparc-*-rtems*): Remove Solaris left-overs. (sparc*-*-*): Remove obsolete sparc86x setting. (sparc-leon*): Default to --with-cpu=v8 and --with-tune=leon. * doc/invoke.texi (SPARC Options): Document -mcpu/-mtune=leon. * config/sparc/sparc.h (TARGET_CPU_leon): Define. (TARGET_CPU_sparc86x): Delete. (TARGET_CPU_cypress): Define as alias to TARGET_CPU_v7. (TARGET_CPU_f930): Define as alias to TARGET_CPU_sparclite. (TARGET_CPU_f934): Likewise. (TARGET_CPU_tsc701): Define as alias to TARGET_CPU_sparclet. (CPP_CPU_SPEC): Add entry for -mcpu=leon. (enum processor_type): Add PROCESSOR_LEON. Reorganize. * config/sparc/sparc.c (leon_costs): New cost array. (sparc_option_override): Add entry for TARGET_CPU_leon and -mcpu=leon.
