rs6000-opts.h (enum processor_type): Add PROCESSOR_PPC8548.
* config/rs6000/rs6000-opts.h (enum processor_type): Add
PROCESSOR_PPC8548.
* config/rs6000/rs6000-cpus.def: Reference it for cpu="8548".
* config/rs6000/rs6000.md (cpu attribute definition): Add ppc8548.
* config/rs6000/8540.md: indicate that the units/patterns apply to
ppc8548 as well.
* config/rs6000/rs6000.c (rs6000_option_override_internal): Rename
default_cpu into implicit_cpu, conveying what --with-cpu was passed at
configure time. Treat implicit_cpu as have_CPU. Pick defaults for SPE
related flags, check that what is queried is supported by the selected
configuration. Rework the single/double_float and MASK_STRING resets to
hit for all the E500 cores (854x + E500MC variants). Select the ppc8540
costs for PROCESSOR_PPC8548 as well.
(rs6000_issue_rate): case CPU_PPC8548 together with CPU_PPC8540.
(rs6000_use_sched_lookahead): Likewise, rewriting function as a case
statement instead of a sequence of ifs.
* config/rs6000/rs6000.h (TARGET_E500): Remove.
(TARGET_NO_LWSYNC): Adjust accordingly.
* config/rs6000/e500.h (TARGET_E500): Remove.
(CHECK_E500_OPTIONS): Adjust accordingly.
* config/rs6000/eabispe.h (SUBSUBTARGET_OVERRIDE_OPTIONS): Remove.
(TARGET_DEFAULT): Reformat definition to match the one in linuxspe.h.
* config/rs6000/linuxspe.h: Likewise.
* config/rs6000/vxworks.h: Remove bogus TARGET_E500 overrides and
superfluous comments.
* config/rs6000/e500-double.h: Remove.
* config.gcc (pick a default with_cpu): For powerpc*-*-*spe*,
default to with_cpu=8548 if --enable-e500-double, and to 8540
otherwise.
(set misc flags section): For powerpc*|rs6000*, remove inclusion
of e500-double.h for --enable-e500-double.
