JavaScript engines particularly benefit from running on 64-bit. Modern JavaScript engines use 64-bit value representation, even on 32-bit.

- marshray 13y agoOK, yeah the fundamental number type of Javascript is the 64-bit floating point double so I could see how the ability of a JIT to emit code to handle 56 bit integers might be useful. But it would still be a tradeoff against the cost of doubling the size of every pointer.
