Reapply "[VPlan] Add canonical IV during construction (NFC)."

2025-05-03T09:54:59+00:00

This reverts commit d431921677ae923d189ff2d6f188f676a2964ed8.

Missing gtests have been updated.

Original message:

This addresses an existing TODO and simply moves the current code to add
canonical IV recipes to the initial skeleton construction, at the same
place where the corresponding region will be introduced.

[LV] Reduce register usage for scaled reductions (#133090)

2025-04-11T13:31:08+00:00

This PR accounts for scaled reductions in `calculateRegisterUsage` to
reflect the fact that the number of lanes in their output is smaller
than the VF.

Depends on https://github.com/llvm/llvm-project/pull/126437

[VPlan] Move auxiliary declarations out of VPlan.h (NFC). (#124104)

2025-02-02T13:44:07+00:00

Nothing in VPlan.h directly depends on VPTransformState, VPCostContext,
VPFRange, VPlanPrinter or VPSlotTracker. Move them out to a separate
header to reduce the size of widely used VPlan.h.

This is a first step towards more cleanly separating declarations in
VPlan.

Besides reducing VPlan.h's size, this also allows including additional
VPlan-related headers in VPlanHelpers.h for use there. An example is
using VPDominatorTree in VPTransformState
(https://github.com/llvm/llvm-project/pull/117138).

[VPlan] Remove VPInstruction::setUnderlyingInstr (NFCI).

2024-02-18T18:50:01+00:00

VPInstruction doesn't rely on the underlying instruction any longer for
codegen, remove the unneeded setUnderlyingInstr.

[Transforms] Use std::nullopt instead of None (NFC)

2022-12-03T05:11:37+00:00

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

[Vectorize] Use std::optional in VPlanSLP.cpp (NFC)

[VPlan] Add Debugloc to VPInstruction.

2021-12-20T15:10:41+00:00

Upcoming changes require attaching debug locations to VPInstructions,
e.g. adding induction increment recipes in D113223.
