## Library testing for [#17219](https://github.com/OpenModelica/OpenModelica/pull/17219) against `wasm-jit`
| | Branch | Run | Compiler | Machine |
| --- | --- | --- | --- | --- |
| Baseline | `wasm-jit` | 2026-10-09 23:48:46 | v1.28.0-dev.1349+gd0e88049cd.rust | ryzen-9950x |
| Pull request | `pr/17219` | 2026-10-10 01:19:27 | v1.28.0-dev.1351+g189551014c.rust | ryzen-9950x |
20205 models compared, **0 improved, 1 regressions**, performance 4 improved, 4 regressions.
| Phase | `wasm-jit` | `pr/17219` | Change | Change, same phase |
| --- | --- | --- | --- | --- |
| frontend | 1:20:25 | 1:17:11 | -4.0% | -4.0% |
| backend | 1:51:33 | 1:50:54 | -0.6% | -0.6% |

| total | 20:05:48 | 19:52:31 | -1.1% | -1.2% |
Time spent on the 20205 models both runs have. The last column counts only the 20204 that reached the same phase in both: a model that fails earlier stops paying for the phases it no longer reaches.

Caveats
- 1 libraries of the baseline run were not tested by the pull request run: Buildings_11.
- 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.
