Subject [GitHub] [incubator-tvm] lixiaoquan commented on pull request #5656: [BYOC] Pattern Language MergeComposite

URL: https://github.com/apache/incubator-tvm/pull/5656#issuecomment-633940335


   Original MergeComposite can apply on any IR, but PatternLang seems can't do that yet.
   
   I run into a issue that if try to match a pattern on IR containing control flow, it will
hang or crash.
