On: JIT-Less V8

[sharpercoder]

But is the increasing complexity (an interpreter added to the codebase) not introducing also another - new - attack vector?

[cromwellian → sharpercoder]

IMHO, interpreters are simpler and easier to understand than optimizing JITs. Just look at the recent V8 range-check elimination bug around WASM optimizing +0 and -0 differently in a Math related intrinsic.

[spacenick88 → sharpercoder]

The interpreter has always been part of the codebase since it is used during startup and while the code is still being JITed

[munificent → spacenick88]

Not always, actually. V8 came out in 2008 and didn't have an interpreter until 2016. For the first eight years, the non-optimization execution was also a JIT, just a simpler one.
