I just saw that PDP has some MMX assembly (old school ;). Do you
think it would be worth turning on, even tho MMX seems to be
deprecated? The code is in externals/pdp/system/mmx
Auto-vectorization only got about 5 or 6 loops.

why is MMX deprecated?
especially, why do you consider MMX deprecated when there is no SSE2
code instead?

Do MMX and SSE have different instruction sets? If so, is SSE preferred
over MMX?
yes they have different instruction sets: MMX can only handle integer
values, while SSE can only handle floating point values.
(only SSE2 added floating point support)
SSE2 is
