SSE3 ≠ SSSE3

Quote:
SSE3, also called Prescott New Instructions (PNI), is an incremental upgrade to SSE2, adding a handful of DSP-oriented mathematics instructions and some process (thread) management instructions.
SSSE3 is an incremental upgrade to SSE3, adding 16 new opcodes which include permuting the bytes in a word, multiplying 16-bit fixed-point numbers with correct rounding, and within-word accumulate instructions. SSSE3 is often mistaken for SSE4 as this term was used during the development of the Core microarchitecture.
Bulldozer and Bobcat are the first AMD processors to support SSSE3 instructions:

My bad, thanks for pointing that out!

So glad I took the option a while back and went all intel

Uhm yeah, well i made my choice before snowleopard came out, the voodoobased kernels for leopard worked just fine so it didn't seem like a big risk to go amd.
However having a macbook pro with snow leopard made me want to migrate to sl on my amd as well, despite the complications:)
But yeah, if i built my computer today i would most likely go for intel:)

Why not let the App run 32-Bit like QTX?

When I did it, it meant selling a lot of stuff buying new, starting again and going against my principles, but to be honest it was well worth it

That's what i do, for me it doesn't really matter but I thought I should report the bug anyway since sooner or later we will run into a app that wont run in 32bit.

I don't know if ssse3 emulation is in the scope of the development of the legacy kernel. But seeing how "fundamental" parts of osx uses it(quicklook?), it wouldn't be a bad idea:)
