[llvm] [TTI] Handle experimental.vp.reverse in BasicTTIImpl (PR #147868)

[Luke Lau via llvm-commits]

https://github.com/lukel97 created https://github.com/llvm/llvm-project/pull/147868

A experimental_vp_reverse isn't exactly functionally the same as vector_reverse, so previously it wasn't getting picked up by the generic VP costing code that reuses the non-VP equivalents.

But for costing purposes it's good enough so we can reuse it.

The RISC-V costs are still incorrect and are showing up as scalarized. #147677 aims to fix part of this.

Subject: [PATCH 2/2] [TTI] Handle experimental.vp.reverse in BasicTTIImpl

A experimental_vp_reverse isn't exactly functionally the same as vector_reverse, so previously it wasn't getting picked up by the generic VP costing code that reuses the non-VP equivalents.

But for costing purposes it's good enough so we can reuse it.

The RISC-V costs are still incorrect and are showing up as scalarized. #147677 aims to fix part of this.
