* 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
