A PR that's about to land (if it hasn't yet) to drop LLVM 10 support (last time I wrote an update we only "considered" it^^)
NewPM did land. NewPM has led to some problems with build times and memory use due to different (and worse?) inlining and unrolling heuristics in some samples of code, but on average the build times did decrease significantly.

getauxval in function init_have_lse_atomics when compiling to nightly aarch64-unknown-linux-musl" rust#89626
E-needs-bisectionA week where improvements outweigh regressions. The highlight of the week is the change to split out LLVM profile guided optimization (PGO) and using clang 13 to compile LLVM which led to improvements in many real world crates (e.g., cargo) in the range of 10%. Most regressions were limited and at most in the less than 1% range. We are seeing more performance changes in rollups which are supposed to be performance neutral. We'll have to decide how to best address this.
Triage done by @rylev.
