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 Søren Holm
