[PATCH] D123537: [VPlan] Model first exit values in VPlan.

[Florian Hahn via Phabricator via llvm-commits]

fhahn updated this revision to Diff 430155.
fhahn marked 8 inline comments as done.
fhahn added a comment.

Address comments, greatly simplify patch. The new version adds VPExitValues for all values used by LCSSA phis. Non-vplan based helper (fixupIVUsers, fixFirstOrderRecurrence, fixReduction) remove VPExitValues for LCSSA phis they handle directly, before fixing the remaining VPExitValues.

Follow-up patches will gradually replace those helpers with dedicated users in VPlan.
