Is there some indication that AMD/Intel are reducing the amount of redundant/repetitious dynamic computations in Zen/SunnyCove's by storing that kind of information in the µop cache for example, such as:

loop:
...
mov -16(%rbp), %eax
...
jne loop

where "mov -16(%rbp), %eax" is replaced by "mov -16(%rbp_translated), %eax"? The latter form would not be using the virtual address translation&checking logic.

Let's give this matter a very clear interpretation:

Transmeta designs were in-order VLIW CPUs, in year 2000. That's basically what Pentium/PentiumMMX with instruction pairing were capable of in years 1993/1996.

Some other, less important, notes:

- There is very low probability that a VLIW CPU could (at the same power limit and chip size) outperform an out-of-order CPU (Pentium Pro or AMD K5 and successors).

- The size of an x86 instruction decode unit decoding an equivalent number of instructions per clock as Transmeta did per clock is not excessively large compared to the size of the rest of an x86 CPU.

- The term used nowadays in place of instruction pairing is instruction fusion. Fusion sounds much cooler than pairing.
