ajeyabsfujitsu opened a new issue, #8423:
URL: https://github.com/apache/incubator-gluten/issues/8423
### Problem description
While building Velox on a system with ARM-SVE, the build fails due to a lack
of explicit support for SVE in Velox, which is understandable since Velox's
documentation does not mention SVE support.
However, when using Gluten, which relies on Velox as its backend, the build
does not fail, even though no SVE-related code exists in Gluten itself.
I would like to know these:
1) Why does Gluten not fail to build when Velox (the backend) does, given
the same system configuration?
2) If SVE-related optimizations are added to Gluten code repo, would the
build still succeed, or would it encounter issues due to Velox's lack of
support for SVE?
