Perhaps someone can help me with debugging cc1.
What I am doing is to run
$ ddd cc1
from the gcc $buildir/gcc

What to do about it? I have
$ gdb --version
GNU gdb (Ubuntu 15.1-1ubuntu1~24.04.1) 15.1
$ python --version
Python 2.7.18
and GCC is from current trunk.
When I just continue and "run", then
Starting program: .../gcc/cc1
This GDB supports auto-downloading debuginfo from the following URLs:
<https://debuginfod.ubuntu.com>
Debuginfod has been disabled.
To make this setting permanent, add 'set debuginfod enabled off'
to .gdbinit.
What's the recommendation here?
Thanks in advance.
