where again, behind the scenes, a hidden micro-coded LD occurs at an address 8(TOC) to be loaded into the immediate operand, as if it were possible to have a full 64 bit operand in the cmpli instruction?
-This could hypothetically be encoded with existing v3.0B instructions, loadingvthe 64 bit immediate into a temporary register, followed by using cmp rather than cmpi:

ld r9, 8(r10) # r10 loaded from TOC
cmp r5, r9
-However the very fact that it requires the extra LD instruction (explicitly, rather than implicitly micro-coded) tells us that there is still a benefit to this approach.
