------- Comment #3 from bonzini at gnu dot org 2006-01-23 08:16 -------
The bug here is that expand_compound_operation uses an unsigned HOST_WIDE_INT
for pos, while the argument to the "zero_extract" rtx's is a const_int, which
is signed. A negative value for zero_extract's position operand is at best
undefined, so it's probably easiest to make expand_compound_operation do
nothing in this case.
