A patch
If that works, that would be great.
I can't easily test it right away, but perhaps you could.

How about this assembler patch?

But then it will warn and not do what it was expected to do.
Anyway, I've rebuilt cc1plus (on a box without new binutils) with hacking up
auto-host.h so that it normally emits .file 0 "..." directive, and w

On the binutils gas side it could be as simple as turning the error into a

Bootstrap is fine if one uses older binutils.
The thing is that cxx11-ios_failure* is built by hand first with -g -O2 -S,
then the assembly is modified by a script and then it is assembled, and as
older assem

--- Comment #8 from Mark Wielaard ---
I am not sure where the -g -O2 -g0 comes from. I must have missed this in my
testing.
The issue is the .file 0 directive, which is special to gas (only valid with
-gdwarf-5).
It is generated by dwarf2out_fi

--- Comment #7 from Jakub Jelinek ---
I'd be for automatic bumping to dwarf5 level if .file 0 is seen, but remember
that it happened and issue an error if .debug_info with version older than 5 is
seen in the file.

--- Comment #6 from Jakub Jelinek ---
The assembler has all the information in the assembly, .debug_info section
contains version etc.

--- Comment #5 from Jakub Jelinek ---
Ah, no, the *.s file is generated with -g, but the assembler isn't able to cope
with it.
I'd say that the assembler shouldn't require any directive or flag but just
assemble it.
Anything else seems to be an a
