Still can't reproduce in my dev tree (but as usual this may have too many patches...). Confirmed on match-and-simplify branch with -fwhole-program. Needs -march=x86-64 as well. 55 /* You want to truncate to a _what_? */ 56 gcc_assert (SCALAR_INT_MODE_P (mode)); (gdb) p mode $1 = V4SImode #4 0x0000000000c1683e in simplify_const_unary_operation (code=NOT, mode=V4SImode, op=0x7ffff66ca470, op_mode=V4SImode) at /space/rguenther/src/svn/match-and-simplify/gcc/simplify-rtx.c:1735 1735 return immed_wide_int_const (result, mode); Likely caused by the wide-int merge. Richard?
