Hello all, I’m writing to ask about the current status of the v850 backend in GCC, specifically in the context of embedded use targeting Renesas RH850-U2A and RH850-U2B devices.
My team develops firmware and hypervisor software for existing RH850-U2A/U2B–based hardware, and we are evaluating whether to continue relying on GCC for ongoing development and long-term maintenance. To help guide that decision, we would appreciate clarification on the following: - Whether the v850 backend is currently considered actively maintained - Whether it is deprecated, or expected to be deprecated or removed in a future release - When the backend last received meaningful updates or active maintenance - The current level of support and test coverage for RH850-U2A and RH850-U2B specifically - Any known limitations, issues, or caveats relevant to bare-metal or embedded deployments - Whether there are recommended GCC versions, patches, or alternative toolchains for teams continuing to support RH850-U2A/U2B Any insight into the present status and future outlook of the v850/RH850 support would be extremely helpful for our planning and risk assessment. Best regards, José Martins OSYX Technologies
