tination operand to the right (toward less significant bit locations), SARX keeps and propagates the most significant bit (sign bit) while shifting.</p>
<p>The logical shift left (SHLX) shifts the bits of the destination operand to the left (toward more significant bit loca-tions).</p>
<p>This instruction is not supported in real mode and virtual-8086 mode. The operand size is always 32 bits if not in 64-bit mode. In 64-bit mode operand size 64 requires VEX.W1. VEX.W1 is ignored in non-64-bit modes. An atte
