Bug ID: 23492
Summary: Support analysing libgfortran.so
Product: libabigail
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: default
Assignee: dodji at redhat dot com
Reporter: dodji at redhat dot com
CC: libabigail at sourceware dot org
Target Milestone: ---
The fine folks behind the freedesktop-sdk flatpak effort stumbled upon abidiff
not supporting libgfortran.so, at least on aarch64. You can see the error at
https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/jobs/87258888:
===============
Comparing ABIs…
===============
master/files/lib/aarch64-linux-gnu/libgfortran.so
=================================================
in die_pretty_print_type at: abg-dwarf-reader.cc:10955: execution should not
have reached this point!
Basically, this means that libabigail needs to understand Fortran binaries.

--- Comment #2 from Mathieu Bridon <bochecha at daitauha dot fr> ---
Dodji said on IRC the debuginfos are needed as well.
You can get them with:
flatpak install --user freedesktop-sdk
org.freedesktop.Sdk.Debug/aarch64/unstable
The files will be located in
~/.local/share/flatpak/runtime/org.freedesktop.Sdk.Debug/aarch64/unstable/active/files/

--- Comment #1 from Mathieu Bridon <bochecha at daitauha dot fr> ---
Here's how you can get the offending file:
1. install flatpak
2. add the remote:
flatpak remote-add --user freedesktop-sdk
https://cache.sdk.freedesktop.org/freedesktop-sdk.flatpakrepo
3. pull the Aarch64 sdk:
flatpak install --user freedesktop-sdk org.freedesktop.Sdk/aarch64/unstable
At this point, you can reproduce the problem:
$ abidiff \
~/.local/share/flatpak/runtime/org.freedesktop.Sdk/aarch64/unstable/active/files/lib/aarch64-linux-gnu/libgfortran.so
\
~/.local/share/flatpak/runtime/org.freedesktop.Sdk/aarch64/unstable/active/files/lib/aarch64-linux-gnu/libgfortran.so
in die_pretty_print_type at: abg-dwarf-reader.cc:10916: execution should not
have reached this point!
Aborted (core dumped)
(yes, comparing the file to itself, why not :P )
(in fact, at this point you have the whole Aarch64 Sdk in
~/.local/share/flatpak/runtime/org.freedesktop.Sdk/aarch64/unstable/active/files
so you can even try the rest of the libraries in there if you want :) )
You can run the above on an x86_64 machine, you shouldn't need to have an
Aarch64 one.

--- Comment #3 from Mathieu Bridon <bochecha at daitauha dot fr> ---
Confirming it fails on all architectures, not just x86_64.
The reason it didn't fail on other arches is that I wasn't telling abidiff to
look at the debuginfo. Now that I do, it fails as well.
It was failing on Aarch64 though, because for some reason libgfortran.so is not
stripped in our Sdk on Aarch64. :-/
---
tl;dr: Now that I'm using abidiff correctly, it fails the exact same way on
libgfortran.so on all architectures.
