I'm seeing the error:

isl/val_gmp.h is included in 0.12 AFAICS so perhaps we should demand 0.12
instead of 0.11 ?
According to isl's ChangeLog, isl_val abstraction was added in version
0.12. Therefore, I think it would be right to demand on 0.12.
Tobias, what do you think about this? Is this fine for the backend,
which uses CLooG to generate Gimple code?
I think so. The latest release of CLooG (0.18.1) was released with isl
0.12.1 and is part of ftp://gcc.gnu.org/pub/gcc/infrastructure/. So
requiring isl 0.12.1 sounds reasonable.
Could you prepare such a patch?
Note that we also still accept CLooG 0.17.0.
In this case we need to update the minimal required CLooG version to
CLooG 0.18.1, right?

ISL 0.13 cannot be used because it dropped some APIs we use
(it's important for testing on branches that a single cloog/isl version
can be used to bootstrap and test on active branches and trunk).
Right. I also believe this is very unfortunate. I copy Sven to let him
now that dropping APIs too quickly regularly causes issues.
Cheers,
Tobias
