[fbarchard]

a quick test of armv7 builds okay locally for me. I did a clang build with bazel.
Are you using cmake or a different compiler?

int8x4 and armsimd is a variation for SIMD that uses GPR registers on mobile ARM that do not have NEON.

Are you using cmake or a different compiler?

Yes, I'm using cmake with a gcc based toolchain.
