PING. The change does not change code in spec2000/spec2006. However, it prevents compile time hangs in some corner cases.

evstupac added a comment to D42607: [LoopStrengthReduce, x86] don't add cost for a cmp that will be macro-fused (PR35681).
It is not obvious that constants in address can somehow hurt performance.
I'll run the patch on the benchmarks I have. However I believe performance issue in PR35861 is about complicated addresses which limit execution ports for stores.

evstupac added a comment to D41467: PR35710: Nary reassociation falls into infinite loop.
To be more precise NaryReassociation works that way:
r0 = v * 16
r1= r0 * 0
r2 = r1 * 1

Other tests that have difference in binaries got the same performance.
Interesting, given we were generating invalid code, what changed there?

How do you think which way we should follow?
Or we can leave regression as is as Solution Cost is better and therefore it is not a problem of newly implemented NarrowSearchSpaceByDeletingCostlyFormulas()?
