## Library testing for [#17111](https://github.com/OpenModelica/OpenModelica/pull/17111) against `wasm-jit`
| | Branch | Run | Compiler | Machine |
| --- | --- | --- | --- | --- |
| Baseline | `wasm-jit` | 2026-10-05 02:16:52 | v1.28.0-dev.1244+gd40906024a.rust | ryzen-9950x |
| Pull request | `pr/17111` | 2026-10-05 15:09:27 | v1.28.0-dev.1246+g1ea36d7a8c.rust | ryzen-9950x |
20031 models compared, **11 improved, 2 regressions**, performance 1 improved, 2 regressions.
| Phase | `wasm-jit` | `pr/17111` | Change | Change, same phase |
| --- | --- | --- | --- | --- |
| frontend | 1:26:48 | 1:25:42 | -1.3% | -1.2% |
| backend | 2:08:05 | 2:06:33 | -1.2% | -1.1% |

| total | 19:11:05 | 19:00:38 | -0.9% | -1.6% |
Time spent on the 20031 models both runs have. The last column counts only the 20018 that reached the same phase in both: a model that fails earlier stops paying for the phases it no longer reaches.

Caveats
- 102 of the 102 libraries were not tested in the same version, or not with the same configuration and reference files, in the two runs; see Library Changes below.
- The baseline is the newest run of wasm-jit, not the commit the pull request is based on, so a difference can also come from something merged into wasm-jit since the pull request was branched.
