* config/rs6000/rs6000-protos.h (rs6000_secondary_reload_class):
Change some of the functions called by macros to being called
through a pointer, so debug functions can be inserted if
-mdebug=addr or -mdebug=cost.
(rs6000_preferred_reload_class_ptr): Ditto.
(rs6000_secondary_reload_class_ptr): Ditto.
(rs6000_secondary_memory_needed_ptr): Ditto.
(rs6000_cannot_change_mode_class_ptr): Ditto.
(rs6000_secondary_reload_inner): Ditto.
(rs6000_legitimize_reload_address): Ditto.
(rs6000_legitimize_reload_address_ptr): Ditto.
(rs6000_mode_dependent_address): Ditto.
(rs6000_mode_dependent_address_ptr): Ditto.
* config/rs6000/rs6000.c (reg_offset_addressing_ok_p): New
function to return true if the mode allows reg + integer
addresses.
(virtual_stack_registers_memory_p): New function to return true if
the address refers to a virtual stack register.
(rs6000_legitimate_offset_address_p): Move code to say whether a
mode supports reg+int addressing to reg_offset_addressing_ok_p and
call it.
(rs6000_legitimate_address_p): Add checks for modes that only can
do reg+reg addressing. Start adding VSX support.
(rs6000_legitimize_reload_address): Ditto.
(rs6000_legitimize_address): Ditto.
(rs6000_debug_legitimate_address_p): New debug functions for
-mdebug=addr and -mdebug=cost.
(rs6000_debug_rtx_costs): Ditto.
(rs6000_debug_address_costs): Ditto.
(rs6000_debug_adjust_cost): Ditto.
(rs6000_debug_legitimize_address): Ditto.
(rs6000_legitimize_reload_address_ptr): Point to call normal
function or debug function. Make functions called via pointer
static.
(rs6000_mode_dependent_address_ptr): Ditto.
(rs6000_secondary_reload_class_ptr): Ditto.
(rs6000_hard_regno_mode_ok): Add preliminary VSX support.
(rs6000_emit_move): Add -mdebug=addr support. Change an abort
into a friendlier error.
(rs6000_init_builtins): Add initial VSX support.
(rs6000_adjust_cost): Fix some spacing issues.
* config/rs6000/rs6000.h (enum reg_class): Add VSX_REGS.
(REG_CLASS_NAMES): Ditto.
(REG_CLASS_CONTENTS): Ditto.
(PREFERRED_RELOAD_CLASS): Move from a macro to calling through a
pointer, to add -mdebug=addr support.
(CANNOT_CHANGE_MODE_CLASS): Ditto.
(SECONDARY_RELOAD_CLASS): Call through a pointer to add
-mdebug=addr support.
(LEGITIMIZE_RELOAD_ADDRESS): Ditto.
(GO_IF_MODE_DEPENDENT_ADDRESS): Ditto.
(enum rs6000_builtins): Add RS6000_BUILTIN_BSWAP_HI.
* config/rs6000/rs6000.md (bswaphi*): Add support for swapping
16-bit values.
(bswapsi*): Set attribute types for load/store. Add combiner
patterns to eliminate zero extend on 64-bit.
(bswapdi*): Add support for swapping 64-bit values. Use ldbrx and
stdbrx if the hardware supports those instructions.

* doc/invoke.texi (Option Summary): Mention -static-libstdc++.
