As the title says, what's the first x86 processor from Intel that supports the following addressing mode?
mov %reg, 8(base, index, 4)
^^^^^^^^^^^^^^^^^
where the content of %reg will be stored to the address base + 4*index + 8 (both base and index are registers).
I only know that 8086 doesn't support this and 80586 supports this. I'm guessing it's 80386 because it's the first 32-bit x86 Intel CPU?

This addressing mode was introduced with the first 32-bit x86 processor, i.e. the 80386.
Ref: 80386 Programmer's reference manual sec 2.5.3.2.
