ctenhank/llvm_clang repository overview

# reference: https://baykara.medium.com/installing-clang-10-in-a-docker-container-4c24a4538af2
# Edited by ctenhank:
# - Base OS: ubuntu 18.04 to 20.04
# - The latest version of LLVM+Clang is 11.1.0, but the only supporting Ubuntu OS is 20.10.
#   The version of LLVM+Clang is downgraded from 11.1.0 to 11.0.0,
#   because the Ubuntu 20.10 seems to be problems in the middle build version.

# This Dockerfile supports only Ubuntu OS.

# If you want to change the LLVM_CLANG_VERSION,
# you must check the Ubuntu version and architecture whether it supports or not.
