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?

Cheers,
Tobias
