That means the support would still be included in GDB 11, the next release, and removed just after the GDB 11 branch is created. There are two parts to it: 1. Native bits for when GDB itself runs on Neutrino (nto-procfs.c) 2. Neutrino target support (nto-tdep.c and friends) We can't compile #1, as that requires the Neutrino SDK. We can build-test #2, as it doesn't require Neutrino-specific include files, but we can't run it. The current plan is to remove both. But if Neutrino target support (#2) is still being used (say, with a custom remote target), but native support (#1) isn't, one option is to only remove the native bits, so we only keep the part that anybody can at least build. If somebody would like the support for Neutrino to stay in GDB, please speak up. If so, we will need a maintainer to step up and become responsible to that port. There is a patch series that implement the proposal here: https://sourceware.org/pipermail/gdb-patches/2020-December/173894.html Thanks, Simon [1] Last one was d7161de46af ("[nto] Improve ABI sniffing.")
