        * config/sparc/sparc.h (ASM_DECLARE_REGISTER_GLOBAL): New macro.
        (RTX_OK_FOR_OLO10): Likewise.
        (GO_IF_LEGITIMATE_ADDRESS): If assembler supports offsetable
        %lo(), allow it in addresses...
        (PRINT_OPERAND_ADDRESS): ... and print it appropriately.
        * config/sparc/sparc.md (sethi_di_medlow_embmedany_pic): sethi %lo()
        does not make sense.
        * config/sparc/sparc.c (sparc_hard_reg_printed): New array.
        (sparc_output_scratch_registers): New function.
        (output_function_prologue, sparc_flat_output_function_prologue): Use
        it.
        * varasm.c (make_decl_rtl): Use ASM_DECLARE_REGISTER_GLOBAL if
        defined.
        * tm.texi (ASM_DECLARE_REGISTER_GLOBAL): Document it.
        * configure.in: Add check for .register pseudo-op support in as and
        check for offsetable %lo().
        * acconfig.h: Add templates for the above checks.
        * configure: Regenerate.
