There are tools designed to do that, e.g. [0] and [1]. When an IR (or MIR) test contains Debug Info, the LLVM DI Metadata makes the test obviously longer. Not all of these metadata are always necessary for the test, so reviewers frequently ask patch submitters for a reduced test case in terms of DI Metadata by recommending some tricks described in [2]. The [2] is just a small proposal for a utility tool that will save us some time (when fully implemented) during making the patches as well as when doing code reviews -- any thoughts on this?<div class=""><br class=""></div><div class="">[0]<span class="Apple-converted-space"> </span><a href="https://llvm.org/docs/CommandGuide/bugpoint.html" class="">https://llvm.org/docs/CommandGuide/bugpoint.html</a></div><div class="">[1]<span class="Apple-converted-space"> </span><a href="https://blog.regehr.org/archives/2109" class="">https://blog.regehr.org/archives/2109</a></div><div class="">[2]<span class="Apple-converted-space"> </span><a href="https://github.com/djolertrk/llvm-metadataburn" class="">https://github.com/djolertrk/llvm-metadataburn</a></div><div class=""><br class=""></div><div class="">Best regards,</div>Djordje</div></div></blockquote></div><br class=""></div></body></html>
