Source: xsimd
Version: 7.5.0-1
Severity: normal
The i386 arch corresponds to 686, i.e. Pentium 6 (P6) released in 1995,
https://en.wikipedia.org/wiki/P6_(microarchitecture)
xsimd provides acceleration through extensions SSE2 and higher.
SSE2 was introduced with the Pentium 4 in 2000 (SSE came the previous
year with Pentium III).
What this means is that generic i386 does not have the instructions
that xsimd takes advantage of, so it's a no-op. xsimd provides no
generic advantage.
That doesn't mean xsimd should not be packaged for i386. It uses
build-time guards (xsimd being header-only), so xsimd i386 might be
useful for users specifically developing applications for cheap
Pentium 4 chips (e.g. embedded device products).
But it does mean that xsimd is failing debci tests on i386 with the
message
"#warning "No SIMD instructions set detected, using fallback mode."
It's just a warning, not an error. It informs that xsimd will run in
no-op mode.
I gather the warning is being sent to stderr, which debci treats as an
error. In that case the debci test can probably "pass" if
debian/tests/control adds
Restrictions: allow-stderr
