Compile apollo using wllvm
I want to use llvm to compile apollo (no matter which version), but apollo uses bazel. I tried to modify the .bazelrc and .apollo.bazelrc and tools/bazel.rc files to change bazel's default compiler to llvm, but I still encountered Got this error:

Please set environment variable LLVM_COMPILER
I tried
export LLVM_COMPILER=clang
but it's uselness.
Do I need to redefine the tool chain?
Has anyone tried using llvm to compile apollo and extract the bitcode? I need help
Apollo is compiled by GCC-7 by default. Here is a repository based on Baidu Apollo 3.0 and 5.0 that uses LLVM for compilation, but I'm not sure if it's still usable. Currently, a Ph.D. student from Nanjing University, China and I have been unable to reproduce the build, and we don't know where the problem lies. It doesn't directly specify Clang in the Bazel script but instead uses the python wllvm package https://github.com/travitch/whole-program-llvm, to extract the LLVM Intermediate Representation for the purpose of static analysis (model checking). https://github.com/h1994st/ApolloLLVMCompile Anyone has suggestions?
don't use wllvm，just use llvm compile apollo directly. if you need instrumentation when you are compiling，you have to combine your pass into llvm. don't use old version llvm and apollo，there will be a lot of problems. I have successfully compiled apollo 7.0 with bazel and llvm(maybe6.0 I forget)
