--- Comment #3 from Iain Buclaw <ibuclaw at gdcproject dot org> --- FYI, with darwin, I've only been using the most recent commit in releases/gcc-11 for testing as there have been a number of issues exposed from that port. I have VMs set-up running 10.4 (PPC), 10.6 (x86_64), 10.13, 10.14, 10.15, 11, and 12. Not yet gotten round to building a bootstrap compiler from gcc-11 just yet though for testing build of master.
