Here's another one:

= Improve code generation testing =

After instruction selection LLVM uses the MI (Machine Instruction) representation for programs. We recently added support for reading and writing this representation to disk (http://llvm.org/docs/MIRLangRef.html <http://llvm.org/docs/MIRLangRef.html>). 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:

- Create a single consistent format instead of the current mix of yaml + IR + MIR
- Do not print unnecessary information (we often print default values where the reader could deduce them)
- Allow the representation to deduce successors of a basic block in common cases
- Allow symbolic names instead of just numbers for virtual registers
- Helper passes: Strip IR information, rename blocks and values, debug information, ...
- Create a bugpoint mode (or a new tool) to reduce .mir test cases
- Write recommendations and guides for .mir based tests
