Re: x86-64 on i386 (was Re: Promoting i386 version over x86_64?)

Another data point for this thread:

x86 is unlike other architectures because 64-bit also has twice as many
registers as 32-bit.  So you get to trade off the benefits of register
allocation across more registers against the memory/cache footprint of
64-bit pointers.

Absolutely. x86-64 is definitely one of my favorite ISAs. Worlds improvement from i386.
