I'm trying to understand the xmm registers better. So I played around with the xmm registers until something went wrong.
I have a value (let's name it fltValue) that contains four floats.
When the source or destination operand is a memory operand, the operand must be aligned on a 16-byte (128-bit version), 32-byte (VEX.256 encoded version) or 64-byte (EVEX.512 encoded version) boundary or a general-protection exception (#GP) will be generated.
