Maybe.

I've tried that one, and it is not possible to do native builds on vax. 
Whatever Kalvis did was not enough. Believe me, I've tried so many times 
it's ridicolous. I doubt anyone have been trying as much as I have.

Not saying that what he's done isn't good or important. It's just that 
it seems gcc 10 just have way too many issues.

"Supposedly" is most likely not. I've tried lots of time. And people 
have reported some success in building various other things, but often 
having to go -O0 to get things through. But I've not seen anyone beside 
me trying to do a full native build. (Well, there was this report now, 
with the same kind of results I'm always getting...)

I have not tried gcc 12 at all. But I know that Maciej did a lot of work 
that sounds really promising. I've more or less given up any hope of gcc 
10. But I still do hope that gcc 12 actually will make a difference.
