The following fixes the condition determining whether we need an
epilogue.
When r12-2429-g62acc72a957b56 introduced this check I didn't notice
the odd condition on review. Richard - do you remember if this
was on purpose?
I've noticed the mismatch with gcc.dg/tree-ssa/predcom-1.c for example.
Bootstrapped and tested on x86_64-unknown-linux-gnu, queued for stage1.
Richard.
* tree-ssa-loop-manip.cc (determine_exit_conditions): Fix
no epilogue condition.
