[Bug rtl-optimization/25890] [4.2 regression] testsuite failure: gcc.c-torture/compile/20051228-1.c

------- 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.
