gcc47-pr48220.patch
Untested patch, which changes using %iN to %oN registers in
DW_OP_GNU_entry_value on SPARC, and doesn't change anything on IA-64 (if we
choose to use variant 1 there).
No idea about mep/mmix/xtensa - the patch might make a difference on xtensa
only I think, as mep doesn't define OUTGOING_REGNO and mmix doesn't define
LEAF_REGISTERS.
