with Extemption
[ https://issues.apache.org/jira/browse/LEGAL-494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16985668#comment-16985668 ]

See also the thread that discusses the rationale behind the exception https://lists.llvm.org/pipermail/llvm-dev/2017-April/112142.html
They mainly want to help cases when an apache license software is being used as a compiler. You don't have to attribute your compiled application to the original compiler.
"The concern there is that users of LLVM compilers (e.g. Clang) would not necessarily know that runtime libraries are implicitly linked into their application, and thus fail to attribute the LLVM project in binaries. The LLVM project generally isn’t widely concerned with binary attribution, but widespread noncompliance with license terms can lead to problems enforcing other terms in the license."

> LLVM has been upgrading their license to Apache with an exemption clause. Our projects include some of the llvm related code in 3rdparty(which is also under MIT atm so it is fine). But it would be great to evaluate the compatibility of their new license.
