(cselib_reset_table): Don't reset cfa_base_preserved_regno instead of REGNO (cfa_base_preserved_val->locs->loc). (cselib_preserve_cfa_base_value): Add regno argument, set 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.

The compiler ends up passing the internal version of the frame pointer register (which has to be eliminated into either SP of FP) to arm_dbx_register_number(). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44694
