INSTRUCTION SUMMARY
Opcode Instruction Description
VEX.DDS.128.66.0F38.W1 90 /r VGATHERDQ xmm1, vm32x, xmm2 Using dword indices specified in vm32x, gather
qword values from memory conditioned on mask
specified by xmm2. Conditionally gathered elements
are merged into xmm1.
VEX.DDS.128.66.0F38.W1 91 /r VGATHERQQ xmm1, vm64x, xmm2 Using qword indices specified in vm64x, gather
qword values from memory conditioned on mask
specified by xmm2. Conditionally gathered elements
are merged into xmm1.
VEX.DDS.256.66.0F38.W1 90 /r VGATHERDQ ymm1, vm32x, ymm2 Using dword indices specified in vm32x, gather
qword values from memory conditioned on mask
specified by ymm2. Conditionally gathered elements
are merged into ymm1.
VEX.DDS.256.66.0F38.W1 91 /r VGATHERQQ ymm1, vm64y, ymm2 Using qword indices specified in vm64y, gather
qword values from memory conditioned on mask
specified by ymm2. Conditionally gathered elements
are merged into ymm1.
