[llvm-dev] Building LLVM through Bazel

[Chris Bieneman via llvm-dev]

There have been discussions about adding a Bazel generator before:
https://cmake.org/pipermail/cmake-developers/2017-July/030144.html <https://cmake.org/pipermail/cmake-developers/2017-July/030144.html>

There does seem to be interest in having that support in CMake, and I can't imagine any insurmountable reason why it couldn't be done. The real issue is that nobody has put in the time to do it.

Writing a short BUILD extension for running tblgen should be possible without too much complexity - not sure what Tensorflow is doing that makes its solution so complicated, it doesn't seem like it should be terribly hard, just a genrule to run tblgen and generate the appropriate files from the td files.
