Changes between Initial Version and Version 1 of Ticket #53076, comment 33

initial	v1
1	1	I think cloog hasn't actually changed at all -- it looks like it just got rev-bumped to build against the newer isl. I suspect you could roll back isl and rebuild cloog and it would build against the older isl just fine.

	3	I notice my installation of cloog is built against the older isl, so I must have rolled isl back before cloog was revbumped. No doubt though, when you start down this road, things can get confusing.

	5	I was looking into how to install a parallel isl 1.14 version -- that in and of itself doesn't look too hard. Then gcc has to be able to be configured to build against a specified isl version, which is usually possible. And finally, I guess it doesn't matter if cloog is built against a different isl version than the one gcc is built against, so that might just be able to be ignored. Messy stuff, to be sure, but we have multiple installations of clang, llvm, gcc, lua, python, and others, so it's do-able.
