- * ARMv6 has UQADD8 instruction, which implements unsigned saturated
- * addition for 8-bit values packed in 32-bit registers. It is very useful
- * for UN8x4_ADD_UN8x4, UN8_rb_ADD_UN8_rb and ADD_UN8 macros (which would
- * otherwise need a lot of arithmetic operations to simulate this operation).
- * Since most of the major ARM linux distros are built for ARMv7, we are
- * much less dependent on runtime CPU detection and can get practical
- * benefits from conditional compilation here for a lot of users.
