Hi! Thanks to the financial support of the Amiga and 68k community, a GCC developer has picked up the work to convert the m68k backend in GCC from cc0 to MODE_CC:
That's great news. Thanks to Bernd for his work and to the donors for their contributions.

I'm not subscribed to gcc-patches, so I'll respond to that here -- On 13 Nov 2019, Bernd wrote,
Since m68k is a target that is not under active development, and probably receives very limited testing, I felt it was important to make it generate as close to the same code as previously.
Building the Debian package archive (and running the package test suites) is not normally considered to be "very limited testing" for a compiler. So this seems a dubious rationale for constraining code generation. Are there implications for open 68k code generation bugs? E.g. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=46393 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52897 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53386 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80786 Thanks. --
