Thank you for driving this Paul, I agree that it is better to have one doc on TableGen. This has been a point of confusion for me as well - when I land in the wrong one and can’t find what I’m looking for :-). -Chris > On Jul 31, 2020, at 1:49 PM, Paul C.

Sorry, I'm not sure what you mean. When I added the new TableGen reference a couple of weeks ago, I don't recall adding it to any list of documents. It appeared as if every document in the docs/ directories was built.

Well, I was hinting at LLVM_DEBUG messages. You can pretty much dump all "actions" Tablegen would take to process a .td file, which should suffice, IMO. On Wed, Aug 5, 2020 at 5:59 PM Paul C.

I'm pondering a new timing feature for TableGen and am wondering whether anyone uses the existing -time-regions option. Some instrumentation for it appears in CodeGenTarget.cpp and GICombinerEmitter.cpp but nowhere else. If no one is using it, I'll be tempted to remove it.
