LLVM Auto-Vectorization Pass with Dependence Analysis for RISC-V RVV

This project implements an LLVM LoopPass that automatically vectorizes loops in C code for the RISC-V Vector Extension (RVV), using dependence analysis to ensure safety.

Features

Analyzes loop dependencies with LLVM's DependenceInfo.
Vectorizes safe loops with RVV intrinsics.
Targets nested loops like matrix multiplication.

Prerequisites

Ubuntu 24.04
LLVM/Clang 18+ (sudo apt install llvm clang cmake)
RISC-V toolchain (sudo apt install gcc-riscv64-linux-gnu)
QEMU-RISCV (sudo apt install qemu-system-riscv64)

Build Instructions

Clone the repo: git clone https://github.com/yourusername/RVVAutoVectorize.git
Build the pass:
```
mkdir build && cd build
cmake ..
make
```
