ix86_split_lea_for_addr transforms a single LEA instruction into a series
of MOV and ADD instructions. For
lea 0x400(%eax, %ecx, 8), %edx
we get
mov %eax, %edx
add %ecx, %edx
add %ecx, %edx
add %ecx, %edx
add %ecx, %edx
add %ecx, %edx
add %ecx, %edx
add %ecx, %edx

I have been looking at them closely to check their impacts on
both Haswell
