Re testing, I tried doing a build on 64 bit OS X, which fails at:
salsa20-crypt.s:364:suffix or operands invalid for `movq' salsa20-crypt.s:370:suffix or operands invalid for `movq'
That sounds vaguely familiar. I think it has been reported earlier, but not fixed.
This instruction, "movq %xmm4, %r8" is used to copy the low 64 bits from an %xmm register to a regular 64-bit register. Any idea on how to write that in a way which makes the osx assembler happy? I'm not aware of any other instruction for doing that type of copy, but any reasonable workaround is appreciated.
