357 LLVM. It gets email about once a month.
359 .. __: http://lists.cs.uiuc.edu/mailman/listinfo/llvm-announce
362 This list is for people who want to be included in technical discussions of
363 LLVM. People post to this list when they have questions about writing code
364 for or using the LLVM tools. It is relatively low volume.
366 .. __: http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev
368 `Bugs & Patches Archive`__
369 This list gets emailed every time a bug is opened and closed, and when people
370 submit patches to be included in LLVM. It is higher volume than the LLVMdev
373 .. __: http://lists.cs.uiuc.edu/pipermail/llvmbugs/
376 This list contains all commit messages that are made when LLVM developers
377 commit code changes to the repository. It is useful for those who want to
378 stay on the bleeding edge of LLVM development. This list is very high volume.

382 `Test Results Archive`__
383 A message is automatically sent to this list by every active nightly tester
384 when it completes. As such, this list gets email several times each day,
385 making it a high volume list.
