In case you're referring to my attempt to port the test case to x86: All the efforts to reproduce the bug on x86 have failed so far. It seems that Gcc is much better in handling bit filed accesses on little endian targets (x86) than on big endian (s390[x], power). In other words, on x86 earlier optimisations prevent the dse2 pass from having to deal with the problematic situation. So, don't wait for me coming up with more test cases; I'll keep trying, but I'm pessimistic. Ciao Dominik ^_^ ^_^ -- Dominik Vogt IBM Germany
