[llvm-dev] TableGen trace facility

[Paul C. Anagnostopoulos via llvm-dev]

A question for those of you who have developed complex TableGen files: Do you think a trace facility would be useful during debugging? The idea is to add a new statement to TableGen along these lines:

  trace tag : value1, value2, ... ;

When encountered, the TableGen parser would display the tag along with the values of the specified value1, value2, etc. The tag is an identifier that makes it easier to distinguish multiple traces.
