Wasm output size problem

Zig 0.17 increases one my wasm lib size from 71k to 81k (about the same as 0.14), whereas 0.15 and 0.16 each shrinked it about 5k. So far not bad. I’m just curious the reasons. I guess it is a balance between percentages of code generation and (non-generated) runtime code in the std lib.
