Available on (x86 or x86-64) and target feature
sse4.1
and x86 only.Expand description
Select a single value in a
to store at some position in b
,
Then zero elements according to IMM8
.
IMM8
specifies which bits from operand a
will be copied, which bits in
the result they will be copied to, and which bits in the result will be
cleared. The following assignments are made:
-
Bits
[7:6]
specify the bits to copy from operanda
:00
: Selects bits[31:0]
from operanda
.01
: Selects bits[63:32]
from operanda
.10
: Selects bits[95:64]
from operanda
.11
: Selects bits[127:96]
from operanda
.
-
Bits
[5:4]
specify the bits in the result to which the selected bits from operanda
are copied:00
: Copies the selected bits froma
to result bits[31:0]
.01
: Copies the selected bits froma
to result bits[63:32]
.10
: Copies the selected bits froma
to result bits[95:64]
.11
: Copies the selected bits froma
to result bits[127:96]
.
-
Bits
[3:0]
: If any of these bits are set, the corresponding result element is cleared.
