--- Comment #13 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to jos...@codesourcery.com from comment #12) > config.sub and config.guess are imported, unmodified, from upstream > config.git. thanks I will try to do that and test it over the next days (I've been using a newish version on arm64-darwin20 for a few months so don't anticipate problems - but who knows). > libtool has lots of local changes, hopefully all of them submitted > upstream but maybe not and maybe some not committed upstream (libtool has > very few commits in recent years, but lots since the 2009 version used in > GCC). As well as checking all the local changes (relative to libtool > commit 2c9c38d8a12eb0a2ce7fe9c3862523026c3d5622, apparently) and applying > them to a new version as needed, updating libtool would also require > reverting libtool commit 3334f7ed5851ef1e96b052f2984c4acdbf39e20c to deal > with a mismatch of --with-sysroot interpretations. The patch I have here is a additional local change (and specific to Darwin), unfortunately, I don't have resources to address the scope of work you describe.
