Cross-Compilation Tutorial : C to RISC-V (+ Vector Extension)

To cross-compile C code to a RISC-V target, we need to following compiler toolchains :

• EPI Fork of the LLVM/Clang Toolchain, which is modified to offer experimental support for RISC-V Vector instructions, as well as vector intrinsics which can be directly called in C code.

• RISC-V GNU Toolchain, which is needed to supplement the missing library/include dependencies in the LLVM/Clang toolchain when cross-compiling.

Progress on the software side :

• At first, we tried to use an experimental version of LLVM/Clang (the epi one) which offers vector intrinsics.

• Issue is that it is going to change heavily, and probably try to adhere to an official standard for risc-v vector intrinsic link - Example of C API for Vector integer arithmetic operations link.

• Interestingly, the RISC-V GNU/GCC toolchain has a branch focusing on developing riscv intrinsic. This branch respects the api agreed on above, and is going to be merged upstream soon when the risc-v vector extension spec v1.0 is released. link. I have pulled that branch and tried to write some programs -> it works well !

• Very important question : we have previously decided to use LLVM/Clang over GNU/GCC, it might be interesting to tak

Arrow FYP - Update on Software Component

General Update

• Progress has been made on porting tests from the MLPerf Inference Benchmark suite to C++.
• I did not start working on the gem5 model yet. I plan to do so over the remainder of the winter break.
