Thanks! I got NetBSD truss to be very reliable with multiple threads, but GDB is misbehaving. > | I can spend some more time on fixing local GDB, upstreaming the support > | and adding support for running the regress test in GDB... this will > | allow us to get more predictable results with future GDB upgrades, cover > | kernel code paths with GDB tests and maybe run regression tests on the > | GDB buildbot. > > Sounds good to me! > I've compared src/ GDB 8.3 and upstream GDB 8.3. There are a lot of differences and it looks like a lot of our changes predate gpl2->gpl3 switch in GDB. I have an impression that sometimes we unintentionally revert to an older GDB code. I will start with upstreaming small code chunks first and getting upstream GDB to work on NetBSD/amd64 with its regression tests... It should be better long term action than mutating local in-tree version. > Thanks, > > christos >
