andps
Usage: ANDPS dest,src Modifies flags: CF OF PF SF ZF (AF undefined)
Performs a bitwise logical AND of the four packed single-precision floating-point values from the 'src' operand and the 'dest' operand, and stores the result in the 'dest' operand.
Bitwise Logical AND For Single FP
ANDPS xmm1,xmm2/mem128 ; 0F 54 /r [KATMAI,SSE]
ANDPS performs a bitwise logical AND of the four single-precision floating point values in the source and destination operand, and stores the result in the destination register.
dst[0-31] := src[0-31] AND dst[0-31],
dst[32-63] := src[32-63] AND dst[32-63],
dst[64-95] := src[64-95] AND dst[64-95],
dst[96-127] := src[96-127] AND dst[96-127].
The destination is an XMM register. The source operand can be either an XMM register or a 128-bit memory location.
