Hi! I just stumbled over [1] and just wanted to add that Debian is reguarly building snapshots of all current gcc versions for a large number of targets, including the testsuites (except for m68k and sh4 at the moment).
The results can always be found on buildd.debian.org. gcc-7:
https://buildd.debian.org/status/package.php?p=gcc-7&suite=sid
gcc-8:
https://buildd.debian.org/status/package.php?p=gcc-8&suite=sid
gcc-9:
https://buildd.debian.org/status/package.php?p=gcc-9&suite=sid
gcc-snapshot:
https://buildd.debian.org/status/package.php?p=gcc-snapshot&suite=sid
So gcc is tested regularly on ia64 and co and it's actively being used to build the whole Debian archive. Thanks, Adrian
