Bisecting

[Søren Holm via Gcc]

Hi

I believe I have found some kind of bug in GCC. The target is a 
cortex-m7 CPU. I do not have an isolated test software so I'm thinking 
of bisecting GCC between GCC 9.4 and 10.1.

Are there any easy way do do a fast "change - compile - test"- cycle - 
and how do I do that? All the guide on building GCC is using huge 
scripts with installs and such. I'm sure the main developers does not do 
that.


Thanks
