The movq +instructions do not trigger the same hardware problems. Unfortunately, +using movq and splitting/combining seems to require too many extra +instructions to help. Perhaps future chip steppings will be better. + + + +NOTES + +The Pentium-4 pipeline "Netburst", provides for quite a number of surprises. +Many traditional x86 instructions run very slowly, requiring use of +alterative instructions for acceptable performance. + +adcl and sbbl are quite slow at 8 cycles for reg->reg. paddq of 32-bits +within a 64-bit mmx register seems better, though the combination +paddq/psrlq when propagating a carry is still a 4 cycle latency. + +incl and decl should be avoided, instead use add $1 and sub $1. Apparently +the carry flag is not separately renamed, so incl and decl depend on all +previous flags-setting instructions. + +shll and shrl have a 4 cycle latency, or 8 times the latency of the fastest +integer instructions (addl, subl, orl, andl, and some more). shldl and +shrdl seem to have 13 and 15 cycles latency, respectively. Bizarre. + +movq mmx -> mmx does have 6 cycle latency, as noted in the documentation. +pxor/por or similar combination at 2 cycles latency can be used instead. +The movq however executes in the float unit, thereby saving MMX execution +resources. With the right juggling, data moves shouldn't be on a dependent +chain. + +L1 is write-through, but the write-combining sounds like it does enough to +not require explicit destination prefetching. + +xmm registers so far haven't found a use, but not much effort has been +expended.
