Warning/error when using simde on clang 17 about simde HOT 5 CLOSED

it does not go away with -DSIMDE_NO_NATIVE, and openmp-simd doesn't help either.

so presumably the SIMDE_VECTORIZE now warns when the vectorization isn't supported?

from simde.

we believe we can safely use -Wno-pass-failed (unfortunately we can't use -march=native as that breaks cross-compiles, ah well). thanks for the help!

from what we could gather, clang doesn't appear to have a way to suppress the warning at the pragma site, which seems pretty reasonable in the general case honestly but we aren't testing for optimizations in the wabt test suite, we're just testing for correctness.

Huh. I don't understand the error. Does it go away if you turn off the SSSE3 implementation? Alternatively, does it get better if you compile with -mssse3 or -march=native?

Also, it is very recommended to compile using -fopenmp-simd -DSIMDE_ENABLE_OPENMP on Clang version 6+ and GGC version 4.9+

That could be. I guess one could check with the Compiler Explorer to see if that code normally is vectorized on other compilers.
