+Subject: [PATCH] Offlineasm warnings with newer Ruby versions
+ https://bugs.webkit.org/show_bug.cgi?id=206233
+
+Reviewed by Yusuke Suzuki.
+
+Avoid a warning about using Object#=~ on Annotation instances, which
+has been deprecated in Ruby 2.7.
+
+* offlineasm/parser.rb: Swap checks to prevent applying the =~ operator
+to Annotation instances, which do not define it.
