https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97865 --- Comment #27 from Iain Sandoe --- tomorrow if there are no further comments (the patch needs minor typographical changes). I'm also testing back-ports for the open branches, and will publish Darwin-specific branches at least for gcc-7.5 (and eventually gcc-6.5 and 5.5 since people are still build the 5 branch for Java) - it all takes time ;)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97865 --- Comment #26 from Jürgen Reuter --- Any news? I did not test the patch you posted in your last comment, but only the one from your git repo. Under the assumption that this is identical to the patch here, it works. So apparently libfortran and the fortran frontend are not affected? When do you expect to merge this?

So with that patch it works. Probably it worked even before your last fix, as I think I cloned the first your repo just with the link above, but was on master, not on the master-wip-config-darwin20, my fault. I compiled/bootstrapped now with Apple clang version 12.0.0 (clang-1200.0.32.27), and just did make -i install, skipping over the error, which I think is not relevant for me. I used my patches for the gmp, mpfr, mpc, though I think it's not relevant for them. In any case I notified their developers about the issue. Hope we get a stable and convincing solution into 11.0.1. Will you then backport this for upcoming 10.3 and 9.4 as well? (for 8 it's probably too late).

Or do I have to build with a special sanitizer flag? The branch contains a patch to enable libsanitizer for darwin20 (libsanitizer *is* built with dynamic_lookup, because it uses undefined weak symbols). So long as the initial configure says that libsanitizer is being built (or rather it doesn't say it's disabled) then it should be present. ** Perhaps the problem are coming primarily from the failed install because of the no-pie issue. I am going to investigate this next. With the last patch on the branch, it would be academic for libgfortran to be built with "undefined, dynamic_lookup" since there are *no* undefined symbols. since DYLD_LIBRARY_PATH no longer works for Darwin, a failed install will no doubt produce a failed test. Will post more when I figure out what's happening with the no-pie issue. In the meantime - you could try a bootstrap with CC/CXX set to a darwin19 gcc 7 or newer (if it's possible).

OK - we need to figure out what's different in the setups (I don't get the same result) - * I found that there was one incorrect case in libgfortran (where there is a direct reference to **environ from the dylib, which is not allowed) - this was being hidden by the 'global dynamic_lookup' -- the master-wip-config-darwin20 branch has a patch now for that too.

I tested your branch. Several observations:
(1) make worked, (I used gmp, mpfr and mpc without patches for them, there
libtool is also outdated, but I'm not sure whether it has any influence)
(2) make check did not work because of the first error below.
(3) make install did produce an error, strangely enough, as make worked without
problem.
(4) I checked that on my system there is an older version of libasan installed.
I thought this comes with every gcc installation, but apparently it
doesn't. Or do I have to build with a special sanitizer flag?
(5) Your branch does NOT solve the problems in our codes, I do see the same
failures in our test suite like with the gcc trunk/master.
The test-suite for the gcc itself did not work because
of this:
sys/types.h

Here you go - this is config.{sub, guess}, libtool and a small patch to enable
libsanitizer for darwin20 (which I'll likely push soon).

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.
[Bug target/97865] libtool needs to be updated for Darwin20.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97865 --- Comment #12 from joseph at codesourcery dot com --- config.sub and config.guess are imported, unmodified, from upstream config.git. 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.
