Perhaps Matthias can shed some light.
please try building gcc-13 with amdgcn-tools-18 for enlightenment. That's what I
would have to do as well.
Here is some enlightenment :-)
I changed the amdgnc-tools dependencies in gcc-13_13.3.0-13 into
amdgnc-tools-19, and this is the error:

So the error is "LLVM ERROR: Unsupported AMDHSA Code Object Version 3"
This leads to the following bug report in GCC [1] - conclusion is that it's
fixed in GCC 14 by commits [2] and [3].
So it seems to me that the options for trixie are:
- Keep LLVM 17 supported.
- Backport those two commits to GCC 13.
Of course it's hard to say up front what the chance of success is of
backporting those two patches. I'm not sure if the risk is worth it at this
point in the release cycle.
(As an aside, I don't think an ICE is the proper way to deal with an
unsupported code object, but OK.)
