[PATCH] select isl-0.15 in download_prerequisites

[VandeVondele Joost]

[-- Attachment #1: Type: text/plain, Size: 258 bytes --]

For the recent fix of PR53852, isl-0.15 is needed, which is already available at ftp://gcc.gnu.org/pub/gcc/infrastructure/ . Thus, it seems to make sense to update the download_prerequisites script, as done with the attached patch.

OK for trunk ?

I just went to the documentation of isl-0.14 and I see that it also
provides the functionality to count the number of isl operations:
isl_ctx_get_max_operations().

isl-0.12.2 does not provide this functionality.

I think it is fine to bump the default version of isl to be downloaded
by default.
Are there other reviewers who would oppose committing this patch?

Thanks,
Sebastian

can 4.8 and 4.9 be built with isl-0.15?

The patch only influences an in-tree build of isl for trunk, so does it matter ?

can isl-0.15 be built with 4.8 and 4.9? ..with an old libc?

(i remember seeing isl-0.14 fail because max_align_t or something
was missing on a slightly older host toolchain..)

isl-0.15 builds for me with gcc 4.6.4, 4.7.4, 4.8.3, 4.9.2, not sure about older libc.

I can't find any reference to max_align_t in the isl-0.15 source.
(for me actually also isl-0.14 builds fine down to gcc 4.6).

Maybe somebody with an older toolchain could test ?

So, OK for trunk ?
