rs6000.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): All constants of size no larger than… 

rs6000.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): All constants of size no larger than a pointer should go in the TOC.

* config/rs6000/rs6000.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): All
constants of size no larger than a pointer should go in the TOC.
Add 'MODE' parameter.
(LEGITIMIZE_RELOAD_ADDRESS): Add MODE parameter to
ASM_OUTPUT_SPECIAL_POOL_ENTRY_P.
(ASM_OUTPUT_SPECIAL_POOL_ENTRY): Likewise.
* config/rs6000/aix.h (SELECT_RTX_SECTION): Likewise.
* config/rs6000/netware.h (SELECT_RTX_SECTION): Likewise.
* config/rs6000/rs6000.c (constant_pool_expr_1): Likewise.
(rs6000_legitimize_address): Likewise.
(rs6000_emit_move): Likewise.
(rs6000_select_rtx_section): Likewise.
(output_toc): Deal properly with outputting small constants like
HImode, and SFmode in 32-bit mode, and DFmode in 64-bit mode.
* config/rs6000/sysv4.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): Add
MODE parameter.  Put small constants in the TOC.

* config/rs6000/rs6000.c (easy_fp_constant_p): All constants are
easy in SImode.
(rs6000_emit_move): When reload calls us with an illegitimate
address, exit early.  Move the change_address calls to one place
at the end of the routine.  Merge the SImode and DImode expanders.
When called by reload to put an integer into a FP register, force
it to memory.

* config/rs6000/rs6000.c (struct toc_hash_struct): Add 'key_mode'
field.
(rs6000_hash_constant): Hash mode too.
(toc_hash_function): Allow for key_mode.
(toc_hash_eq): Structures are different if key_mode differs.
(output_toc): Add 'mode' parameter.  Save key_mode.
* config/rs6000/rs6000.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY):
Pass 'mode' parameter.
* config/rs6000/rs6000-protos.h (output_toc): Add 'mode' param.
