uschindler opened a new pull request, #12376:
URL: https://github.com/apache/lucene/pull/12376
This PR allows us to better test the new Panama Vector Support, although the
hardware may not fully support it. Currently when developers are running tests,
C2 is disabled, so the provider never enables itsself. Also CPUs only with AVX1
are disabled.
To actually test the correctness of the provider with unsupported hardware,
at the moment developers have to pass `export CI=true` or similar to enable C2
which sows down tests.
This PR adds a boolean to `lookupProvider()` called `testMode` which
enforces its usage. The code is only used during tests, actually *only* in
TestVectorUtilProviders, e.g. see here (the second test prints "test mode"
while loading):
```
