Martin Kustermann af1b5b8044 [dart2wasm] Switch binaryen optimization levels from -O3 to -Os ... We want dart2wasm be comparable to dart2js / dart2aot, the ladder two are much more conservative with inlining compared to current dart2wasm. The -O3 is described in the binaryen sources as agressive for performance and therefore willing to compromise code size. The -Os is more nuanced: It will perform many optimizations that are done in -O3 (and e.g. not in -O2) but it will make inlining less agressive. This reduces flute compile-time by 10% and code size by 10% This benchmark results are mixed (some things get faster, some things slower). Naturally there'll be specialized micro benchmarks that get hit hard by this. Where performance matters we should rather make dart2wasm use better inlining heuristics and annotate code with `@pragma('wasm:prefer-inline')` Change-Id: Idf7e75e4e385629c9cec66359efe0afe50db3e72 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/352523 Reviewed-by: Slava Egorov <vegorov@google.com> Commit-Queue: Martin Kustermann <kustermann@google.com>		2024-02-14 13:45:13 +00:00
