Description

Converts a vector register to a mask register. Each element in the destination register is set to 1 or 0 depending on the value of most significant bit of the corresponding element in the source register.

The source operand is a ZMM/YMM/XMM register. The destination operand is a mask register.

EVEX.vvvv is reserved and must be 1111b otherwise instructions will #UD.

Operation

VPMOVB2M (EVEX encoded versions)

(KL, VL) = (16, 128), (32, 256), (64, 512)
FOR j <-  0 TO KL-1
    i <-  j * 8
    IF SRC[i+7]
          THEN  DEST[j] <-  1 
          ELSE  DEST[j] <-  0
    FI;
ENDFOR
DEST[MAX_KL-1:KL] <-  0

VPMOVW2M (EVEX encoded versions)

(KL, VL) = (8, 128), (16, 256), (32, 512)
FOR j <-  0 TO KL-1
    i <-  j * 16
    IF SRC[i+15]
          THEN  DEST[j] <-  1 
          ELSE  DEST[j] <-  0
    FI;
ENDFOR
DEST[MAX_KL-1:KL] <-  0

VPMOVD2M (EVEX encoded versions)

(KL, VL) = (4, 128), (8, 256), (16, 512)
FOR j <-  0 TO KL-1
    i <-  j * 32
    IF SRC[i+31]
          THEN  DEST[j] <-  1 
          ELSE  DEST[j] <-  0
    FI;
ENDFOR
DEST[MAX_KL-1:KL] <-  0

VPMOVQ2M (EVEX encoded versions)

(KL, VL) = (2, 128), (4, 256), (8, 512)
FOR j <-  0 TO KL-1
    i <-  j * 64
    IF SRC[i+63]
          THEN  DEST[j] <-  1 
          ELSE  DEST[j] <-  0
    FI;
ENDFOR
DEST[MAX_KL-1:KL] <-  0
