if you configure with --enable-stage1-languages=all, 1) will all the libraries be built three times during bootstrap, or just once? 2) is it still possible to just build the stage1 compiler without the libraries? > >>>Q6) How to clean up everything except for the stage1 compiler and > >>> its runtime (libgcc, libmudflap, libgomp)? > >>make restrap (which will also start a bootstrap) > > > >Would it be possible to add a possibility to just clean up the things, > >without restarting the bootstrap (i.e., to move everything to the > >state I would have after "make stage1-bubble" if I started from the > >scratch)? > > Actually, I was wrong as "make restrap" will also delete the runtime. > The closest things to what you want are: > - "make distclean-stage2"; however it will leave there all the target > libraries if they have already been compiled, not only the runtime. > - "make distclean-stage2 clean-target"; which will remove also the runtime. thanks, the "make distclean-stage2 clean-target" actually is exactly what I need (although I specified something different :-) Zdenek
