We are following MLIR source code compilation for RISCV architecture shared as per official document.
####################################################################################
root@ubuntu:~/llvm-project-main/build# cmake -G "Ninja" \
-DCMAKE_C_COMPILER=$(which clang) \
-DCMAKE_CXX_COMPILER=$(which clang++) \
-DLLVM_ENABLE_PROJECTS="mlir" \
-DLLVM_TARGETS_TO_BUILD="RISCV" \
-DCMAKE_BUILD_TYPE="RelWithDebInfo" \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DLLVM_BUILD_EXAMPLES=ON \
