Package: gcc-12
Version: 12.3.0-4
Severity: important
Dear Maintainer,
It seems that the Debian package of GCC 12 was compiled with BMI1 (and
BMI2) instructions (perhaps the wrong -march setting is being
used?). At least apparently (see below). Those are relatively new
instruction sets, and are not supported by older CPUs.
* What led up to the situation?
Compiling darktable from the git repository (I am a darktable
translator, so installing the pre-packaged version doesn't work for
me). I noticed another darktable submitted an issue to darktable:
https://github.com/darktable-org/darktable/issues/14701
and realized it was exactly the same error that occurred when I tried
to compile darktable on my machine.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Just cloned and tried to compile darktable:
git clone https://github.com/darktable-org/darktable.git
git submodule update
cd darktable
./build.sh --prefix /usr/local --build-type Release
* What was the outcome of this action?
Illegal instruction while compiling:
[ 20%] Building C object bin/CMakeFiles/lib_darktable.dir/common/iop_order.c.o
during GIMPLE pass: graphite
/home/magnus/camera2/test2/darktable-debian12/darktable/src/common/iop_order.c:

make[1]: *** [CMakeFiles/Makefile2:2473: bin/CMakeFiles/lib_darktable.dir/all]
Error 2
make: *** [Makefile:156: all] Error 2
* What outcome did you expect instead?
Full compilation without problems.
Some more info:
- Clang compiles darktable without problems
- Could not test gcc-11, because 12 is the minimum version that
the darktable build script accepts
- The darktable issue has some more information on this, incuding
some guided debugging (a darktable maintainer helped me and
the issue submitter find the exact problem, which was BMI1 and
BMI2 instructions being executed during compilation):
https://github.com/darktable-org/darktable/issues/14701
For me the illegal instruction was blsr, and for the issue submitter,
it was shlx (see the issue).
My CPU is an AMD FX-8320E. The original issue submitter had an Intel
i7-3770K CPU.
The illegal instruction is in 'isl_hash_table_init'. Now, the strange
part is that
grep -r isl_hash_table_init *
inside gcc sources doesn't return anything. But as the original
darktable issue reporter mentioned, recompiling GCC manually seems to
fix the issue. For lack of better information, and since recompiling
gcc seems to have fixed the issue for one person, I am submitting this
bug to the gcc-12 package. Sorry if it's not the correct place.
Please tell me if there is anything else I can do to help.
Thank you!
Jeronimo
