The C frontend is always built, as it is required for a bootstrap. In any case, skipping the C frontend won't help much; it is not very large. > Also when I modify the treelang codes, do I have to do a complete rebuild > of the gcc even just core to get the treelang built? or is there a way to > just patch the treelang make straight into the pre-bootstrapped > (previously made and installed) gcc? I'm not quite sure what you are asking, but the Makefile dependencies should normally do the right thing. If middle-end object files are being rebuilt, then that is probably necessary. In some cases it helps to use ccache. Ian
