* The "v" variable is the native backend, which is only defined when SIMD is supported by hardware.
473
473
Only use when USE_BASIC_SIMD is defined.
474

Will not work on scalar emulation.
475
- * The "scalars" array is only defined for targets with direct access to SIMD registers. (SSE)
476
- Only use when USE_DIRECT_SIMD_MEMORY_ACCESS is defined.
477
- Will not work on NEON or scalar emulation.
478
- * The "scalars" array is ony defined when SIMD is turned off.
479
- Cannot be used when USE_BASIC_SIMD is defined.
475
+ * The "scalars" array is available when emulating a type that does not exist or the SIMD vector has direct access to the memory.
476
+ Do not rely on these for accessing elements, because otherwise your code will not be able to compile for ARM NEON.
