Code Generation Unit Partitioning Meeting

Meeting proposal info

• Title: Code Generation Unit Partitioning Meeting
• Type: Technical

Summary

The MIR Opt working group is making progress with various MIR optimizations.
However, our efforts are sometimes thwarted by compilation time regressions due to LLVM.
We believe the primary contributing factor in these situations is the codegen unit partitioning algorithm.

We would like to solicit ideas from the rest of the compiler team regarding improvements that can be made to the algorithm.

Additional information can be found in this gist.
