Richard Guenther - Re: [PATCH] Do not set BB_SUPERBLOCK in loop-unroll.c:split_edge_and_ins (original) (raw)

This is the mail archive of the gcc-patches@gcc.gnu.orgmailing list for the GCC project.

I would love to say that I will fix the problem for you, and perhaps I will, if you are willing to wait for about two weeks (before I get rid of some other work that pilled on me just now).

I have no problem with waiting, but I can also fix the problem if I have a test case (I have a hackish patch, in fact). All I really want to see is whether any test suite failures show up somewhere, so that we have this code covered in the test suite.

To be honest, I don't believe we'll have any test suite failures, or other problems. But right now I see no other way to make sure, than by just trying. When something breaks after all, we can revert the patch for the moment and I can work on a proper fix (and of course I'd appreciate your help, if possible). But I can only fix a problem properly if I know that there is a problem to begin with.

I really would not propose this unusual way forward if I would see a better way out...
