Re: Fix PR tree-optimization / 31946 :


Hi,

The patch broke bootstrap for fortran. I've tested an updated patch
that fixes that . However the testsuite needs to be fixed for the
fallout with this patch as it allows for vectorization with different
peeling limits for the testcases mentioned in the PR .

I'll submit a complete patch once I have worked through the test fails
but that will have to be much later this the evening.
