VPBROADCASTM

Broadcasts a doubleword value from a memory location to all doubleword elements of the destination vector register.

The following table covers what the source and destinations can be:

DO NOT support LOCK

This instruction requires AVX support. It is not available in compatibility mode; it MUST be executed in 64-bit mode or protected mode.

The destination register is overwritten by the broadcasted value. If the memory operand is not aligned to a 4-byte boundary, a general-protection exception (#GP) MAY occur depending on the alignment check (AC) flag in the EFLAGS register. To avoid performance degradation or faults, ensure the source m4 is naturally aligned.
