We recently added support for reading and writing this representation to disk (<a href="http://llvm.org/docs/MIRLangRef.html" class="">http://llvm.org/docs/MIRLangRef.html</a>). Usage of this format for writing tests is growing and so is the desire to improve the format, tools and workflow. Improvements would be welcome:</div><div class=""><br class=""></div><div class="">- Create a single consistent format instead of the current mix of yaml + IR + MIR</div><div class="">- Do not print unnecessary information (we often print default values where the reader could deduce them)</div><div class="">- Allow the representation to deduce successors of a basic block in common cases</div><div class="">- Allow symbolic names instead of just numbers for virtual registers</div><div class="">- Helper passes: Strip IR information, rename blocks and values, debug information, ...</div><div class="">- Create a bugpoint mode (or a new tool) to reduce .mir test cases</div><div class="">- Write recommendations and guides for .mir based tests</div><div class=""><br class=""></div><div class="">- Matthias</div><br class=""><div><blockquote type="cite" class=""><div class="">On Jan 16, 2017, at 5:18 AM, Vassil Vassilev via llvm-dev <<a href="mailto:llvm-dev@lists.llvm.org" class="">llvm-dev@lists.llvm.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hi folks,<br class=""><br class=""> Happy new year!<br class=""><br class=""> Last LLVM Developers' Meeting I had a BoF: 'Raising Next Generation LLVM Developers'.
