invoke.texi: Add mcmodel to powerpc options.
* doc/invoke.texi: Add mcmodel to powerpc options.
* configure.ac: Add HAVE_LD_LARGE_TOC test.
* configure: Regenerate.
* config.in: Regenerate.
* config/rs6000/linux64.opt (mcmodel): New.
* config/rs6000/linux64.h (TARGET_USES_LINUX64_OPT): Define.
(TARGET_CMODEL): Define.
(SUBSUBTARGET_OVERRIDE_OPTIONS): Check user -mcmodel choice,
select CMODEL_MEDIUM default.
* config/rs6000/rs6000.h (enum rs6000_cmodel): New.
(TARGET_CMODEL): Define default.
* config/rs6000/rs6000.c (cmodel): New variable.
(rs6000_explicit_options): Add cmodel field.
(rs6000_handle_option): Handle -mcmodel.
(create_TOC_reference): Add largetoc_reg param. Generate high,
lo_sum rtl for CMODEL_MEDIUM and CMODEL_LARGE. Update all callers.
(rs6000_delegitimize_address): Recognise new toc reference rtl
and minimal-toc rtl.
(rs6000_legitimize_reload_address): Handle new toc references.
(print_operand_address): Handle legitimate_constant_pool_address_p
match before lo_sum.
(rs6000_eliminate_indexed_memrefs): Tidy.
(rs6000_emit_move): Tweak threshold for inlining constants.
Keep rs6000_emit_allocate_stack large stack frame offsets
loaded into r0 inline.

(rs6000_mode_dependent_address <LO_SUM>): False for new toc refs.
(offsettable_ok_by_alignment): New function.
(rs6000_emit_move): Address suitably aligned local symbol_refs
relative to the toc pointer for -mcmodel=medium.
(legitimate_constant_pool_address_p): Make param const_rtx. Add
strict param. Allow lo_sum version of addressing. Verify reg
used for -mminimal-toc and -mcmodel != small. Update all callers.
* config/rs6000/constraints.md: Update for above change.
* config/rs6000/predicates.md: Likewise.
* config/rs6000/rs6000.md (tls_gd_aix): Generate -mcmodel=medium/large
code.
