Motorola m68k support saved from being removed In GCC 11

[nogginthenog]

While the Motorola 68000 32-bit processors are from the 80's and early 90's, there still is a loyal following of hobbyists who managed to save the "m68k" compiler back-end from being removed in GCC 11.

The m68k back-end in GCC was at risk of being removed due to plans for GCC 11 to drop the CC0 representation code and the back-ends still depending upon it. M68k was the most notable user relying upon the deprecated CC0 representation but there are also other back-ends like AVR (AVR micro-controller), CRIS (the Axis Communications' ETRAX CRIS embedded processors), H8300 (the Renesas H8 microcontrollers), VAX (DEC VAX), and CR16 (National Semi CompactRISC). But now at least m68k is safe.

I just noticed the patch is from a certain Bernd Schmidt who wrote UAE.

As in what's used in a lot of CNC / 3D Printer controllers? I reckon this might have had more to do with it than us.

But a win is a win.

That's good news. I wonder if Microchip will make sure, the AVR backend is ported to the current representation!?

AVRs are used everywhere. I found one in an electric toothbrush.
But I think you misunderstand. AVR is not yet supported in GCC 11.

The 68k changes are not related to the other platforms.
