We saw a massive improvement to instruction-counts across +over a hundred benchmarks, thanks to #110050 an improved encoding scheme for the +dependency graphs that underlie incremental-compilation. However, these +instruction-count improvements did not translate to direct cycle time +improvements. We also saw an improvement to our artifact sizes due to #115306. +Beyond that, we had a scattering of small regressions to instruction-counts that +were justified because they were associated with bug fixes. + +Triage done by **@pnkfelix**. +Revision range: [15e52b05..7e0261e7](https://perf.rust-lang.org/?start=15e52b05ca8f63e0da27c808680388717e5b997e&end=7e0261e7ea2085bdc0bc3d0fd6776bf343473858&absolute=false&stat=instructions%3Au) + +3 Regressions, 2 Improvements, 5 Mixed; 2 of them in rollups +84 artifact comparisons made in total + +[Full report - pending](https://github.com/rust-lang/rustc-perf/blob/master/triage/2023-09-13.md) ### [Approved RFCs](https://github.com/rust-lang/rfcs/commits/master)
