Thanks for the report; sorry about the breakage. What target is this for? I'm not seeing these issues on x86_64-pc- linux-gnu. I think that what's happening is that my patch changed various existing dump messages from -fopt-info from being "note: " to being "optimized: " or "missed: ". gcc/testsuite/lib/prune.exp has: # Ignore informational notes. regsub -all "(^|\n)\[^\n\]*: note: \[^\n\]*" $text "" text which strips out all notes after dg-message directives have been checked. Presumably these pre-existing "note: " dump messages were being ignored, and are no longer matching that pattern. I can see two approaches to fixing this: (a) extend those lines in prune.exp to also ignore "optimized: " and "missed: " (b) figure out the criteria for when these messages appear, and add new dg-optimized and dg-missed directives to the tests in questions, with suitable filters. Is there a link to the .log files somewhere so I can see the precise messages in question? (e.g. are they all "loop versioned for vectorization to enhance alignment"?). Thanks, and sorry again about the breakage. Dave
