(4) In Go assembly syntax, NOP is a zero-width pseudo-instruction serves generic purpose, nothing
related to real ARM64 instruction. NOOP serves for the hardware nop instruction. NOOP is an alias of
HINT $0.

Examples:

	VMOV V13.B[1], R20      <=>      mov x20, v13.b[1]
	VMOV V13.H[1], R20      <=>      mov w20, v13.h[1]
	JMP (R3)                <=>      br x3

* developers run different builds
* developers can have different hardware, or have different settings
* developers run all kinds of other things on their machines that can slow them down

				// Note that the specific value of float32(math.NaN()) can vary based on
				// whether the architecture represents signaling NaNs using a low bit
				// (as is common) or a high bit (as commonly implemented on MIPS
				// hardware before around 2012). We believe that the increase in clarity
				// from identifying "NaN" with math.NaN() is worth the slight ambiguity
				// from a platform-dependent value.

division, the 2-by-1 guess uses an implicit uₙ = 0.

Note that using a 2-by-1-digit division here does not mean calling ourselves
recursively. Instead, we use an efficient direct hardware implementation of
that operation.

Note that because q is u/v rounded down, q·v must not exceed u: u ≥ q·v.
If a guess q̂ is too big, it will not satisfy this test. Viewed a different way,

	_AT_PAGESZ   = 6  // System physical page size
	_AT_PLATFORM = 15 // string identifying platform
	_AT_HWCAP    = 16 // hardware capability bit vector
	_AT_SECURE   = 23 // secure mode boolean
	_AT_RANDOM   = 25 // introduced in 2.6.29
	_AT_HWCAP2   = 26 // hardware capability bit vector 2
