It's the AT&T syntax because AT&T are the one who unleashed that on the world against the wishes of everyone. See the sibling comment: > The AT&T folks did not even wait for Intel's assembler [...] Nor did they closely model their assembler after it. They just took the assembler they already had for the PDP-11 and adapted it with minimal changes for the 8086.

Wow, is your bias showing. "Against the wishes of everyone"? How about the wishes of those who wanted an x86 assembler before Intel got around to releasing theirs? And who wanted to be able to not have to switch their brains into a backward syntax when working on an x86?

  Probably "against the wishes of assembly language programmers who were familiar with microprocessors like the 8080 and Z-80 - and those who would have preferred to standardize on the official intel syntax rather than deal with two different and incompatible assembly language syntaxes."

    So, reading the comments here I got the impression that the 8086/8088 order was backwards from everything else before it. Did the 8080 and Z-80 have the same order as the 8086? But even then, you have worlds converging. The 8086 was (barely) capable of running Unix, whereas the Z-80 definitely was not. Was the 8086 a part of the PDP-11 minicomputer world, or was it part of the 8080/Z-80 world? Well, it was both. Complaining that one world produced an assembler before the other did is... a bit exclusivist. Also whiny.

The x86 has a larger instruction set and address space (1MB) but as it turns out, early Unix kernels didn't need that much RAM either.
