[llvm-dev] I am leaving llvm:

>Somewhat recently a code of conduct was adopted. It says that the community tries to welcome people of all "political belief". Except those whose political belief mean that they don't agree with the code of conduct. Since agreement is required to take part in the conferences, I am no longer able to attend.

>The last drop was llvm associating itself with an organization that openly discriminates based on sex and ancestry (1,2). This goes directly against my ethical views and I think I must leave the project to not be associated with this.
