Hello, I noticed that Debian's ld-linux.so didn't provide the SystemTap probes that allow GDB to get notified of shared library changes, and avoid re-reading the whole list from the debugged process all the time. I saw this thread here [1], which, if I understand correctly, ended up in disabling the feature because of build failures. It has been 10 years since then, many issues have probably been ironed-out, so I was wondering if you would consider trying to enable the feature again, at least starting with amd64.
I don't have a pressing need for it. I'm a GDB developer, I noticed some tests behaving differently on my Debian machine than on my other non-Debian machine, and it lead me to this observation. But since it helps GDB be a bit more efficient, I think it would be nice to have it enabled. According to Luis Machado, GDB expert for the ARM architecture, it's not possible to use those probes for ARM, because the probe addresses don't carry the Thumb bit. So it would have to be a feature enabled only for certain arches in any case. For AArch64, it should be fine. Thanks, Simon [1] https://lists.debian.org/debian-glibc/2014/06/threads.html#00097
