But that is a different issue and really this should be handled correctly in that since the target supported by default the unaligned handlers, it should not set STRICT_ALIGNMENT to 1. Now the target can have an option to turn it on, witness PPC-elf/PPC-linux which has one as some embedded hardware/OS's don't support the unalignement trap. -- Pinski -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26721
