From f52913b6edb7f2026f204eaf8a3e1472bab510cd Mon Sep 17 00:00:00 2001 From: Michael Maitland Date: Tue, 27 Jun 2023 09:19:36 -0700 Subject: [PATCH] [RISCV] Add VLOptimizer pass The purpose of this optimization is to make the VL argument, for instructions that have a VL argument, as small as possible. This is implemented by visiting each instruction in reverse order and checking that if it has a VL argument, whether the VL can be reduced. This is done before vsetvli insertion to reduce the number of generated vsetvlis. It can also reduce the number of vsetvli instructions that toggle the VL (the vtype may still need to get set). The list of supported instructions is currently whitelisted for safety. In the future, we could add more instructions to isSupportedInstr to support even more VL optimization.
