The compiler team had our weekly triage meeting on 2019-10-17. You can find the minutes on the compiler-team repository. Each week, we have general announcements from the team followed by check-ins from two of the compiler team working groups.

Announcements

• Design meeting on debuginfo strategy tomorrow (2019-10-18) on Zulip.

• The traits working group had a design meeting yesterday on lazy normalization.

• @nikomatsakis has been looking into lazy normalization specifically for constants and hopes to have some notes to share soon.

• The LLVM ICE-breakers working group is nearly ready to go live.

• @spastorino has nearly finished interning Place projections which is an incremental step to MIR 2.0.

• @centril is continuing to work on splitting libsyntax apart which will decrease the amount of code librustc depends on.

Working group sync

wg-mir-opt

• @wesleywiser Moved promoted MIR out of mir::Body #63580

• @wesleywiser Reimplemented the ConstProp optimization pass on top of the existing const eval code #64419

• @spastorino Converted mir::Place to no longer be a recursive data structure #63420

• There is ongoing work in both const prop and place refactorings.

• We've figured out a plan for "weird" place projections like dereferences (virtual locals).
