You *need* to build the kernel with -fno-dce and -fno-tree-dce? Are you working around another compiler bug? Take a look at the attached scripts I use. ./o2list.sh > o2list.txt ./permute-options.sh o2list.txt > run.sh chmod u+x run.sh Normally I can simply run the results on a target and know which is good and which is bad. Unfortunately you have to link each into a kernel and try to boot. Cheers, Carlos.
