No worries.

Maybe with the latest fixes, yes. But as mentioned, I've been trying to 
self built forever, and I used to do that all the time in the past.
Sadly, I'm now in a situation where I no longer can do the tests on a 
real 8650, since it's been put in storage. But I still have a 4000/90 
that I test on.

For cross compilation, I've never had any issues with -O<whatever>. It's 
always for me just been an issue with native builds. Are you sure any of 
those hacks were actually required for cross compilations?

Yeah. I tried looking at gcc multiple times, but always get depressed 
after looking at it too much.

I still think/hope that the work that's gone into gcc 12 will be a big leap.
