Support for LEON processor
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.
Initialize cost array to leon_costs if -mtune=leon.
* config/sparc/sparc.md (cpu attribute): Add leon. Reorganize.
Include leon.md scheduling description.
* config/sparc/leon.md: New file.
* config/sparc/t-elf: Do not assemble Solaris startup files.
* config/sparc/t-leon: New file.
* config/sparc/t-leon3: Likewise.
