We weren't using the "union" cargo feature for the smallvec crate, which reduces the size of a SmallVec by one machine word. This feature requires Rust 1.49 but we already require much newer versions. When using Wasmtime to compile pulldown-cmark from Sightglass, this saves a decent amount of memory allocations and writes. According to `valgrind --tool=dhat`: - 6.2MiB (3.69%) less memory allocated over the program's lifetime - 0.5MiB (4.13%) less memory allocated at maximum heap size - 5.5MiB (1.88%) fewer bytes written to - 0.44% fewer instructions executed Sightglass reports a statistically significant runtime improvement too: compilation :: cycles :: benchmarks/pulldown-cmark/benchmark.wasm Δ = 24379323.60 ± 20051394.04 (confidence = 99%) shrink-abiarg-0406da67c.so is 1.01x to 1.13x faster than main-be690a468.so!
