>Have you seen the actual MPF presentation, by chance?
My copy says:
"SSE Unaligned Load-Execute mode
–Remove alignment requirements for SSE ld-op instructions
–Eliminate awkward pairs of separate load and compute instructions
To improve instruction packing and decoding efficiency"
Is it just the unaligned penalty that will go away?
Or will all of SSE now accept unaligned memory ops?
In case of the latter, what about the traditional #GP(0)?
Not another mode bit, eh?
