IMHO that's a wrong thing to do.
Either you should just stick the testcase under gcc.c-torture/compile/
so that it gets tested with all -O* options (I think many people configure
the compiler for i386-*-* target), or if you really want it in gcc.dg,
it should be something like:
/* { dg-do compile } */
/* { dg-options "-O1" } */
/* { dg-options "-O1 -march=i386" { target { i?86-*-* && ilp32 } } } */
