-Notice how the WaR Waits on `r9` cause 2 instructions to finish per cycle (5 micro-ops per 2 cycles) instead of the 4 per cycle for the Register Renaming version, this means the processor's resources will eventually be full, limiting total throughput to 2 instructions/clock.

 For the following table:
-- Assumes that `ldu` instructions are split into two micro-ops in the decode stage. The address computation is denoted "#5.a" and the memory read is denoted "#5.m".
-- Assumes that a mechanism for forwarding from a FU's result latch to a waiting operation is in place, without having to wait until the result can be written to the register file.
-- "Av `r3`" denotes that the value to be written to `r3` is computed and is available for forwarding but can't yet be written to the register file.
-- "SW: #4" denotes that the instruction is waiting on the shadow produced by instruction #4.
-- "Rf #5:`r5`" denotes that the instruction reads the result latch for instruction #5's new value for `r5` through the forwarding mechanism.
