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
