道听途说64bit
Monday, April 28th, 2008Words from Diablo-D3:"you can feed ia32 to amd64/emt64 processors without something else translating it. but heres a secret: x86-64 isn't native either. they translate it into an internal RISC-like micro-op language. they just end up issuing more instructions for ia32 than they do x86-64 because there are no micro-op instructions for 32-bit stuff."
