I implemented this as a new optimization pass, so I will upload it.
I'm thinking of getting a new Phabricator review number and linking it from this comment section.

Code explosion is the symptom, not the sickness. It's caused by using experimental intrinsics. Experimental intrinsics are a detriment to progress. They end up creating a ton more work and are designed to be inevitably replaced.

So, IIUC, this is changing tryCreateRecipe to move the interleave recipe creation to the caller, buildVPlanWithVPRecipes. The dependencies with the sink values is recorded initially, then the plans are created, then the sinks are applied and, if any, the interleave groups.

rengolin added a comment to D53137: Scalable vector core instruction support + size queries.

I would find it much easier to review with an incremental strategy based on regression tests. For instance, with ToT opt, the attached testcase fails (error: '%r' defined with type '<4 x i1>' but expected '<vscale x 4 x i1>'). I would add a patch to fix that, and maybe other similar, really simple cases. We could then proceed to more complex examples, run some of the passes that come after the vectorizer on them, and progressively fix the places required to make them pass, with focused tests for each hurdle that we run into. It shouldn't be too hard to reduce such snippets from the tests you've already been running.

@hsaito The test no_switch.ll failed because remarks aren't written now by default, so without -pass-remarks-analysis. I've just removed the corresponding check from the test. But, I think, the NFC label from diff/commit should also be removed in this case because the behavior is changed a little bit. No other problems with tests in the LoopVectorize directory.

I don't understand why having a function with a lot of arguments is better than a private method getting access to the class' members. Why are private methods in C++ at all, they also are used only from class methods and can be replaced with static util functions getting required class members as arguments.

Exactly. Non-constant values can become constant. Constant values can be guarded by vscale-dependent runtime guards (both hand-written and compiler generated). My preference is to leave this not restricted to vscale == 1 values, but rather allow all values that can be supported at runtime, and have it be UB if, at runtime, the relevant index is not available.
