In demos the Transmeta processors was shown to support multiple instruction sets - per https://en.wikipedia.org/wiki/Transmeta#Code_Morphing_Softwa... , they demoed pico-Java , and also there were rumors of PowerPC compatibility.

Although you're probably right - none of those options made it into a shipping product, only x86.

I guess today's equivalent VLIW chip would be Tachyum Prodigy, not super confident about it.. https://www.tachyum.com/products/#products-prodigy

Nvidia's denver2 cores work this way. Shipped on an android tablet about 10 years ago. Not sure what happened to them after that.
