Comment (by Joel Sherrill): There is no GCC 10 RSB recipe for RTEMS 5. You could modify the arm gcc version in your **local** 5 branch based on what is in 6. You will need to keep the newlib version the same, but the gcc should be able to be changed. I don't know what it would be called but a more bleeding edge gcc might be nice for a release branch. For rtems master, we refer to that as rtems7. For sure, updating GCC past 7 on rtems5 will break some BSPs. At least some PowerPC BSPs need SPE support which was dropped after 7 and I think the ARM changed some compiler flags. But, in theory, there isn't anything wrong with having a newer GCC as an alternative. But it would have to be disclaimed that all testing for the release was done with GCC 7 and anything newer would be at some risk of breakage. And I don't know what the toolchain would be called. It isn't 6 and isn't 5. -- Ticket URL: <http://devel.rtems.org/ticket/4408#comment:3> RTEMS Project <http://www.rtems.org/> RTEMS Project
