Probably, but I don't know for sure. > And any chance for userland support for this feature? No. The -fdump files are for compiler developers. There is a chance for userland support for a different feature, perhaps along the lines of the existing -aux-info option. If you can describe exactly what it is that you want the compiler to dump, and if it seems to be useful to people other than just you, then it may be possible to implement it. Of course, it's even more likely to happen if you send a patch, although it would still be necessary for this feature to be useful in general. This is a case where writing a compiler plugin may be the best answer. However, you will need to move up to gcc 4.5 for plugin support. Ian
