+
+The compiler team had our weekly triage meeting on 2019-10-17.
+You can find the [minutes](https://rust-lang.github.io/compiler-team/minutes/triage-meeting/2019-10-17/) on the [compiler-team](https://github.com/rust-lang/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](https://github.com/rust-lang/compiler-team/issues/186) tomorrow (2019-10-18) on Zulip.
+  - [Link to full meeting](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/design.20meeting.202019-10-18/near/178476377)
+
+- The traits working group had a [design meeting](https://github.com/rust-lang/wg-traits/tree/master/minutes) 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](https://rust-lang.github.io/compiler-team/working-groups/mir-opt/)
+
+- [@wesleywiser] Moved promoted MIR out of `mir::Body` [#63580](https://github.com/rust-lang/rust/pull/63580)
+
+- [@wesleywiser] Reimplemented the `ConstProp` optimization pass on top of the existing const eval code [#64419](https://github.com/rust-lang/rust/pull/64419)
+
+- [@spastorino] Converted `mir::Place` to no longer be a recursive data structure [#63420](https://github.com/rust-lang/rust/pull/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).

+
+### [wg-meta](https://rust-lang.github.io/compiler-team/working-groups/meta/)
+
+- The [Inside Rust](https://blog.rust-lang.org/inside-rust/index.html) blog has launched.
+
+- The [ICE-Breaker group](https://rust-lang.github.io/rustc-guide/ice-breaker/about.html) has been formed!
+
+- The [LLVM ICE-Breaker group](https://rust-lang.github.io/rustc-guide/ice-breaker/llvm.html) is also being formed.
