// We want to allow 128-bit wide SIMD if either NEON is available (as
// detected by GEMMLOWP_NEON), or whether SSE4.2 and Clang is
// available (in which case we will use the neon_sse.h library to
// share source between the two implementations). We use SSE4.2 to
// ensure we can use the full neon2sse library, and we use Clang as
// GCC has issues correctly compiling some parts of the neon2sse
// library.

// Otherwise, the INT8_NEON_SIMD variable will be undefined.
