dwarf2out.c (multiple_reg_loc_descriptor): Use dbx_reg_number for spanning registers.
2013-05-21 Christian Bruel <christian.bruel@st.com>
* dwarf2out.c (multiple_reg_loc_descriptor): Use dbx_reg_number for
spanning registers. LEAF_REG_REMAP is supported only for contiguous
registers. Set register size out of the PARALLEL loop.
