--- Comment #18 from Stan Johnson <userm57 at yahoo dot com> --- $ git clone git://gcc.gnu.org/git/gcc.git $ cd gcc $ git checkout master I'm testing a manual bootstrap of "gcc version 14.0.0 20230524 (experimental) (GCC)" now, accessed via git as shown above. It will still take about 24 more hours for the bootstrap to finish (I'll send an update if it fails), but with gimple-match.cc (and generic-match.cc, which was not affected in my tests) split up, it looks like it will finish ok (it's currently in about the middle of stage 2 and has successfully compiled all the gimple-match-n.cc files). Note that Gentoo's emerge of gcc-13 behaves a little differently than a manual bootstrap. I don't know why, since I think I'm using Gentoo's ./configure options in the manual bootstrap, but in Gentoo's emerge of gcc, they seem to run cc1plus and "as" simultaneously for each compilation, perhaps aggravating the memory issue for gimple-match.cc (or maybe not, since the problem is virtual memory exhausted, not swap space exhausted). Anyway, it looks like the solution was already close. Does anyone know whether the change will be backported to gcc-12 or gcc-13 available from ftp.gnu.org/pub/gnu/gcc? Thanks to all of the GNU developers who continue to make modern tools available for use on old hardware!
