Two issues discovered with the patch. One is easy:
--- gcc/dwarf2out.c 2010-05-05 17:14:56.000000000 +0200
+++ gcc/dwarf2out.c 2010-05-05 20:51:40.000000000 +0200

{
rtx piece = *piece_loc;
diff -= decl_piece_bitsize (piece);
- piece_loc = &XEXP (piece, 1);
+ *piece_loc = XEXP (piece, 1);
free_EXPR_LIST_node (piece);
}
/* Add padding if needed. */
The other shows on various libgcc files with -m32 - apparently SRA leaves
sometimes the original decl in the IL together with SRAed variables, the patch
assumed that either the SRAed variables, or the original appear, but not both.
