It's unfortunate, but i= f you > want something to progress, you just need to ping it now Thats why I wrote my mail. I also see that we had some comment on that patch yesterday. It is simply by accident that I run into the very old bug today and find that old bug entry. I found it, because I applied these patches for years again and again to every new gdb version and had a notice on my patching script for that bug. > If the patch was sent > in 2016 and hasn't seen any activity since, there's no real change that = some > GDB maintainer will pick it up, review it, test it and merge it out of n= owhere > (unless they need it themselves). > > And indeed, there's isn't a maintainer dedicated to AVR in GDB, so that = doesn't > help. > As always in open source, if there is nobody actively self working on something, nothing will change.

As I applied that patch today against 9.1 release and get everything working, it feels ok to apply it to the mainline. Even if it will break something, we will have some user reports for that and maybe the next patch. But simply doing nothing because maybe something can be broken did also not help. As mentioned, the patch is local to avr. It can be tested with simulavr as with real jtag interface. Testability is not a problem in that case. It only makes me wonder that all people simply apply the patches by them self and nobody is crying to get it in the next release :-) Maybe avr is dead as all the arm stuff has taken over the small 8 bit systems. And for me it is only a small project which I want to run today... but keeps me searching for old bugs :-) If I can support something, maybe for testing, feel free to ask. Klaus
