[SOLVED] __builtin_prefetch

[julkas]

I need  C  __builtin_prefetch analog.
Any hint?

[Thaddy]

isn't it just (intel/amd):

Code: Pascal  [Select][+][-]

1. procedure prefetch;inline;asm prefetch;end;

Note that prefetch is not very useful on modern processors.
(But it had a marked improvement on old amd64.)

It's simply called Prefetch. It will only have an effect on x86 (all three bitnesses), PowerPC (both bitnesses) and ARM as only there it's backend is implemented. On other platforms won't have an effect.
