Log:
    PR target/46729
    * config/sparc/sparc.h (GLOBAL_OFFSET_TABLE_REGNUM): New macro.
    (PIC_OFFSET_TABLE_REGNUM): Rewrite in terms of above macro.
    * config/sparc/sparc.c (pic_helper_needed): Delete.
    (global_offset_table): Likewise.
    (pic_helper_symbol): Rename to...
    (got_helper_rtx): ...this.
    (global_offset_table_rtx): New global variable.
    (sparc_got_symbol): Likewise.
    (sparc_got): New static function.
    (check_pic): Use local variable and call sparc_got.
    (sparc_tls_symbol): Initialize to NULL_RTX.
    (sparc_tls_got): In non-PIC mode, reload the GOT register for Sun TLS
    and 32-bit ABI and copy the GOT symbol to a new register otherwise.
    (get_pc_thunk_name): Rename local variable.
    (gen_load_pcrel_sym): New wrapper around load_pcrel_sym{si,di}.
    (load_pic_register): Rename to...
    (load_got_register): ...this.  Adjust and call gen_load_pcrel_sym.
    (sparc_expand_prologue): Do not test flag_pic.
    (sparc_output_mi_thunk): Use pic_offset_table_rtx directly.
    (sparc_file_end): Test got_helper_rtx instead of pic_helper_needed.
    Rename local variable and do not call get_pc_thunk_name again.
    * config/sparc/sparc.md (load_pcrel_sym): Add operand #3.
