Errors while running CTest

This runs on a Milk-V Pioneer machine with a sophgo 2042 processor. This only implements RVV 0.71, which is why the tests fails with illegal instruction.

My question is if the rvv support is enabled runtime? How and where is the runtime detection done? I would expect that the runtime detection would catch this and highway would fall back to the generic implementation.

For ffmpeg we have adapted a runtime test for detecting compliant rvv 1.0 support and I wonder if we can do something similar for highway.

Yes, we detect at runtime, the code is here: https://github.com/google/highway/blob/master/hwy/targets.cc#L621.

Thanks, that's a good idea. We'd welcome such a patch with inline asm.

I have implemented the fix in pull request #2127 that only enables the HWY_RVV target if tail agnostic mode is supported, mask agnostic mode is supported, and the length of a vuint8m1_t vector is at least 16 bytes.

I think this is now fixed, thank you @johnplatts :)
