Syntax

VectorRegister VectorLoadSignedByte4
(
const void * Ptr
)

Remarks

Loads 4 signed BYTEs from unaligned memory and converts them into 4 FLOATs. IMPORTANT: You need to call VectorResetFloatRegisters() before using scalar FLOATs after you've used this intrinsic!

Returns

VectorRegister, float(Ptr[1]), float(Ptr[2]), float(Ptr[3]) )Looks complex but is really quite straightforward: Load as 32-bit value, unpack 4x unsigned bytes to 4x 16-bit ints, then unpack again into 4x 32-bit ints, then convert to 4x floats

Parameters

Parameter	Description
Ptr	Unaligned memory pointer to the 4 BYTEs.
