no, using x86_64 means more registers, sse2 as default floating point
instruction set, better calling convention (register passing vs.
stack) or in other words in most cases faster code.
Indeed. Intel 64 (x86_64) is really a different animal. More registers,
different behaviors, and not just an LP64 version of what was there
before. I've spent the last few weeks finally reading the x86_64 docs on
my Kindle and really look forward to the older stuff just dying.
