        * cselib.h (cselib_preserve_cfa_base_value): Add regno argument.
        * cselib.c (cfa_base_preserved_regno): New static variable.
        (cselib_reset_table): Don't reset cfa_base_preserved_regno instead

        cfa_base_preserved_regno to it.
        (cselib_invalidate_regno): Allow removal of registers other than
        cfa_base_preserved_regno from cfa_base_preserved_val.
        (cselib_finish): Set cfa_base_preserved_regno to INVALID_REGNUM.
        * var-tracking.c (adjust_mems): Replace sp or hfp even outside
        of MEM addresses, if not on LHS.
        (reverse_op): Don't add reverse ops for cfa_base_rtx.
        (vt_init_cfa_base): Adjust cselib_preserve_cfa_base_value caller.
