What will happen if MIPS architecture doesn't support MSA?

[dusan.simicic, 2017/04/05 13:36:32]

If MSA instructions are not supported, SIMD operations from TF graph should be
lowered. CpuFeatures::SupportsWasmSimd128() is used for detection whether
lowering mechanism will be activated or not (wasm-compiler.cc:3871 and
cctest/wasm/wasm-run-utils.h:398).
