POR
Usage: POR dest,src Modifies flags: None
Performs a bitwise logical OR operation on the 'src' operand and the 'dest' and stores the result in the 'dest'.
MMX Bitwise OR
POR mm1,mm2/m64 ; 0F EB /r [PENT,MMX]
POR xmm1,xmm2/m128 ; 66 0F EB /r [WILLAMETTE,SSE2]
POR performs a bitwise OR operation between its two operands (i.e. each bit of the result is 1 if and only if at least one of the corresponding bits of the two inputs was 1), and stores the result in the destination (first) operand.
The 'src' operand can be an MMX technology register or a 64-bit memory location or it can be an XMM register or a 128-bit memory location. The 'dest' operand can be an MMX technology register or an XMM register. Each bit of the result is set to 1 if either or both of the corresponding bits of the first and second operands are 1; otherwise, it is set to 0.
EXAMPLE:
