[VPlan] Update final IV exit value via VPlan.

[fhahn]

Model updating IV users directly in VPlan, replace fixupIVUsers.

This completes the transition towards modeling all live-outs directly in VPlan.

Depends on #110004,
#109975 and
#112145.

[github-actions]

✅ With the latest revision this PR passed the C/C++ code formatter.

[fhahn]

Updated based on latest version of #112145, should be good for a first look, but probably best to wrap up #112145 first

Changes

Model updating IV users directly in VPlan, replace fixupIVUsers.

This completes the transition towards modeling all live-outs directly in VPlan.

Depends on #110004,
#109975 and
#112145.

Changes

Model updating IV users directly in VPlan, replace fixupIVUsers.

This completes the transition towards modeling all live-outs directly in VPlan.

Depends on #110004,
#109975 and
#112145.

Are these handled when building native VPlan? Otherwise better pass null to avoid recording, or define as return value - to be ignored here, instead of collecting them uselessly?

[fhahn]

[ayalz]

This part is obsolete.

[ayalz]

Regarding this being "handled elsewhere", should all exiting IV values be handled first by extracting the last lane, whether resumed by the scalar loop or used in the exit block? Then, as a separate (conceptually optional) subsequent optimization, replace such extractions by precomputing the end values, for both scalar loop and exit block users.

[fhahn]

Sounds good, this effectively means updating all scalar VPIRINstructions wrapping phis together, using the same logic. Might be good to first land this patch and then consolidate the phi handling, to reduce the diff?

[ayalz]

Reducing diff here and following up is fine. Worth leaving behind a TODO somewhere.

[fhahn]

Added the TODO to to place where we call addResumePhiRecipeForInduction

[ayalz]

Exiting IV values can be optimized for both out-of-loop users, both those reaching the scalar loop and those in the exit block. Rather than taking care of the former here and of the latter some 80+ LOC below, passing an IVEndValues map of the end-values created here to be reused there, it would be better to optimize both out-of-loop users together.

Scalar loop resume values use the post-increment IV, i.e., the "end value" of the IV, whereas exit block users may use the post or pre increment IV. However, both types of exit block users also use the "end value" of the IV - the latter with an additional step taken backwards.

So how about doing the following: start with "legalizing" all exiting IV users to extract the last lane, as part of initial VPlan construction. Then, as part of optimizing VPlan, canonicalize exit-block users who use the pre-increment IV, to use the post-increment IV instead, followed with taking the additional step back (at the exit block). Finally, replace every extraction from a post-increment IV feeding out-of-loop users, with a precomputed end-value. WDYT, worth doing so, now or as follow-up?

[fhahn]

Sounds good, as per comment above would probably be good to do as follow-up, as it would probably further increase the diff if pulled in here?

[ayalz]

ok. Worth leaving behind a TODO somewhere.

[fhahn]

Added where addResumePhiRecipeForInduction is called, thanks

[ayalz]

Now missing this opportunity to optimize into an end value?

[fhahn]

Yes, currently we don't try to optimize if there are multiple exits, although we could add some extra code.

[ayalz]

Good to note at commit message that some opportunities may be lost, and leave some TODO to regain them?

[fhahn]

Will do thanks!

[ayalz]

Note that fast is used and required - optimizing an exiting FP IV value by precomputing it using multiplication could change its value, compared to the value obtained by extracting the last lane - which may also differ from the original exiting value due to vectoring the FP IV by VF=2...

[fhahn]

Ak

[ayalz]

LGTM, adding final comments.

[ayalz]

ok. Worth leaving behind a TODO somewhere.

[ayalz]

Hmm, this is indeed confusing; should fixHeaderPhis() also hookup the operand across the backedge of induction header phi recipes, as it does for reductions and FORs? Thereby supporting its VPHeaderPHIRecipe::getBackedgeValue() API. Admittedly, this may contradict #82270(?)

[ayalz]

I.e., are all optimizable WideIV's expected to have their end values precomputed?

[ayalz]

Part of TODO?

[ayalz]

Something like

Suggested change

	static void
	/// If there's a single exit block, optimize its phi recipes that use exiting IV values by feeding them precomputed end values instead, possibly taken one step backwards.
	static void

[fhahn]
