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

1. Clone the repo: git clone https://github.com/yourusername/RVVAutoVectorize.git
2. Build the pass:

   mkdir build && cd build
   cmake ..
   make
