Re: [RFA] Improved linker-debugger interface
Hi Mark,
I will make only several technical fix ups.

No longer, there is development version of utrace-less SystemTap.

This is unrelated. While you can use glibc SystemTap probes for additional
functionality from kernel you do not have to. You can use arbitrary kernel
(probably not even Linux one as long as you build glibc there), GDB always
fetches the probe points from glibc on its own in userland.

It is only about FSF glibc, neither related to SystemTap nor related to Red
Hat.
