So isn't that yet another thing that needs to be changed/fixed in gas?
Plus on the gcc side add a test for that once it is fixed in binutils?

I think this is a GCC bug. We can't assign the same file number to different
files:
# 82 "s-atocou.adb" 1
...
.file 1 "a-stzunb.adb"
This seems to be Ada specific. I can't find a testcase in C nor C++.

# 82 "s-atocou.adb" 1
isn't a .file assignment though.
As I said earlier, if we don't want to revert the r11-3693 change and be able
to specify -gdwarf-5 etc. to gas even when compiling files that contain
explicit .debug_info from the compiler, then we need gas to act as if all that
option affects is the version of the .debug_line emitted for explicit
.file*/.loc* directives if present and nothing else (whenever the assembly
contains manual
.file*/.loc* directives or .debug_{info,line,...} sections). So, basically,
gas can start preparing for generation of its own .debug_* sections but should
roll all that back when it sees .file/.loc directives or user
.debug_{info,line} sections (perhaps some others).
Or, the other option is not to pass -gdwarf-5 to gas, but pass
-gdwarf-line-version=5 or whatever other new option, which would only change
the decision on if gas emits .debug_line section because of .file*/.loc*
directives (and .debug_line is not present), what version of that to use.

That is the intention indeed, and I believe that is what binutils gas should be
doing. There used to be a bug where that didn't work for .file 1, but I thought
that was fixed upstream. Is this different from
https://sourceware.org/bugzilla/show_bug.cgi?id=26740
The assembly posted doesn't seem complete, what does ada really pass to gas?

Like I said above, that is the intention. So if it doesn't work like that it is
simply a bug in gas. It would be helpful to attach the preprocessed file that
ada generates to investigate what is really going on.

That would be another option. But I like to first understand what is really
going on here.

Created attachment 49432

a-stzunb.s.xz
The assembly (though, I don't have binutils 2.35.1+ around, so can't verify
easily myself now).
