## Library testing for [#17197](https://github.com/OpenModelica/OpenModelica/pull/17197) against `wasm-jit`
| | Branch | Run | Compiler | Machine |
| --- | --- | --- | --- | --- |
| Baseline | `wasm-jit` | 2026-10-08 18:01:38 | v1.28.0-dev.1320+g1a9b63447c.rust | ryzen-9950x |
| Pull request | `pr/17197` | 2026-10-08 20:00:37 | v1.28.0-dev.1318+gc61f832468.rust | ryzen-9950x |
20205 models compared, **2 improved, 1 regressions**, performance 5 improved, 3 regressions.
| Phase | `wasm-jit` | `pr/17197` | Change | Change, same phase |
| --- | --- | --- | --- | --- |
| frontend | 1:20:28 | 1:16:30 | -4.9% | -4.9% |
| backend | 1:51:30 | 1:50:05 | -1.3% | -1.3% |
| simcode | 0:22:58 | 0:22:27 | -2.2% | -2.2% |
| templates | 0:12:35 | 0:11:59 | -4.8% | -4.8% |

| simulate | 8:13:45 | 8:17:54 | +0.8% | +0.8% |
| verify | 0:14:05 | 0:13:52 | -1.6% | -1.6% |
| total | 19:58:42 | 19:39:10 | -1.6% | -1.7% |
Time spent on the 20205 models both runs have. The last column counts only the 20202 that reached the same phase in both: a model that fails earlier stops paying for the phases it no longer reaches.

Caveats
- 3 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.
- 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.
