LLVM Announcements List</a>: This is a low volume list that provides important | |
announcements regarding LLVM. It gets email about once a month.</li> | |
<li>The <a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev">Developer's | |
List</a>: This list is for people who want to be included in technical | |
discussions of LLVM. People post to this list when they have questions about | |
writing code for or using the LLVM tools. It is relatively low volume.</li> | |
<li>The <a href="http://lists.cs.uiuc.edu/pipermail/llvmbugs/">Bugs & | |
