Finally if you do believe prefetching is a good alternative to a

then I challenge you to implement it in a experimental branch of the
free pascal compiler, so the prefetch idea can be tried out and
tested !
Why don't you try yourself whether it has a positive effect? "prefetch"
is already part of FPC's RTL since quite some time:
http://www.freepascal.org/docs-html/rtl/system/prefetch.html
... and the compiler itself uses it already for several years.
Out of interest: In what situations does the compiler use it?
iirc somewhere in the hash lists and inside the assembler writer, just
grep for "prefetch(" in the compiler sources ;)
Ah... inside the compiler's sources. I thought you meant "the compiler
inserts calls to prefetch in specific situations". ^^
