* config/arm/arm.h (TARGET_SWITCHES): Add

-m{no-}single-pic-base.  Correct help string for -mshort-load-words.
(TARGET_OPTIONS): Add -mpic-register=.
(ARM_FLAG_SINGLE_PIC_BASE, TARGET_SINGLE_PIC_BASE): Define.
(arm_pic_register_string): Declare.
(NEED_PLT_GOT): Delete, replace with ...
(NEED_GOT_RELOC, NEED_PLT_RELOC): ... these.  New macros.
(OUTPUT_INT_ADDR_CONST): Replace NEED_PLT_GOT with NEED_GOT_RELOC.
(ASM_OUTPUT_MI_THUNK): Replace NEED_PLT_GOT with NEED_PLT_RELOC.
* config/arm/arm.c (arm_override_options): Add new option
-mpic-register=N.
(arm_pic_register_string): New variable.
(arm_finalize_pic): Respect TARGET_SINGLE_PIC_BASE.
(output_func_prologue): If TARGET_SINGLE_PIC_BASE, treat the PIC
register as never live.  Use NEED_PLT_RELOC not NEED_PLT_GOT.
(output_return_instruction): Likewise.
* config/arm/elf.h (NEED_PLT_GOT): Delete, replace with ...
(NEED_GOT_RELOC, NEED_PLT_RELOC): ... these.  Define to flag_pic.
* config/arm/arm.md: Use NEED_PLT_RELOC in place of NEED_PLT_GOT.

* invoke.texi (ARM Options): Fix spelling.  Remove duplicate
mention of -msched-prolog.  Document new options -msingle-pic-base
and -mpic-register=.
