Combine-functions

Optimized byte-combining functions.

Subtopics

Combine64u

(combine64u a7 a6 a5 a4 a3 a2 a1 a0) merges unsigned bytes, producing the 64-bit unsigned interpretation of {a7, a6, a5, a4, a3, a2, a1, a0}.

Combine64s

(combine64s a7 a6 a5 a4 a3 a2 a1 a0) merges unsigned bytes, producing the 64-bit unsigned interpretation of {a7, a6, a5, a4, a3, a2, a1, a0}.

Combine32u

(combine32u a3 a2 a1 a0) merges unsigned bytes, producing the 32-bit unsigned interpretation of (a3 << 24) | (a2 << 16) | (a1 << 8) | a0.

Combine32s

(combine32s a3 a2 a1 a0) merges unsigned bytes, producing the 32-bit signed interpretation of (a3 << 24) | (a2 << 16) | (a1 << 8) | a0.

Combine16u

(combine16u a1 a0) merges unsigned bytes, producing the 16-bit unsigned interpretation of (a1 << 8) | a0.

Combine16s

(combine16s a1 a0) merges unsigned bytes, producing the 16-bit signed interpretation of (a1 << 8) | a0.
