[LV] Align legacy cost model to vplan-based model for gather/scatter w/ uniform addr. (#155739) This patch check if the addr is uniform in legacy cost model to align vplan-based cost model after #150371. This patch fixes llvm-test-suite assertion (https://lab.llvm.org/buildbot/#/builders/210/builds/1935) due to cost model misaligned after #149955 under RISCV. I've tested this patch (on top of #149955) on the llvm-test-suite locally with crashed options `rva23u64`, `rva23u64_zvl1024b` and build successfully. Since this fix will change LV, I think would be better to create a PR to fix this.
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
