### Rust Compiler Performance Triage
90+
91+
A large amount of noise in the comparisons this week, likely due to new
92+
probabilistic query hash verification increasing likelihood of changes in each
93+
benchmark; solutions are being tracked in [rustc-perf#1105].
94+
95+
Otherwise, though, the week largely amounted to a neutral one for performance.
96+
There were some regressions, particularly in doc builds, as a result of the
97+
addition of portable SIMD. These are relatively speaking minor and primarily
98+
impact small crates.
99+
100+
[rustc-perf#1105]: https://github.com/rust-lang/rustc-perf/issues/1105

### Approved RFCs
112+
113+
Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These
114+
are the RFCs that were approved for implementation this week:
115+
116+
* *No RFCs were approved this week.*
117+

> If a normal add is [a waffle iron ](https://en.wikipedia.org/wiki/Waffle_iron), SIMD add is a
167+
> double or quadruple waffle iron. You can make 2 or 4 or more waffles at the same time.
168+

169+
> In case of waffles it would be called SIMW: **S** ingle **I** ron, **M** ultiple **W** affles.
170+

171+
> It's not multithreading - because you open and close the waffle iron for all the waffles at the
