This. People fail to understand the Itanium wasn't necessarily the only representative for VLIW.
Better compiler tech in the past few years (you mentioned JIT for example, which Denver has adapted to do quite well) has made VLIW a strong technical contender in several markets. Alas, the overhead cost of OoO is no longer the issue in modern computer architecture.
- CalChris 9y agoDenver is a JIT but the microarchitecture is 7-way superscalar [1]. A lot of the Transmeta people ended up on Denver and I'll guess they didn't want to repeat VLIW.

- gpderetta 9y agoAnandTech reports [1] Denver being VLIW. They might be wrong though. [1] http://www.anandtech.com/show/8701/the-google-nexus-9-review/3 http://www.anandtech.com/show/8701/the-google-nexus-9-review...

The Denver 2.0 CPU is a seven-way superscalar processor supporting the ARM v8 instruction set and implements an improved dynamic code optimization algorithm and additional low-power retention states for better energy efficiency. https://blogs.nvidia.com/blog/2016/08/22/parker-for-self-driving-cars/ https://blogs.nvidia.com/blog/2016/08/22/parker-for-self-dri...
