<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I've made some more changes (now it is only takes 12% in a Debug compilation)..Thanks,Rolf, for the hints.
Changed l by le (to avoid one vs l mistakes).
Basically, now it does what the comment says. I've changed pos=-posInt-1 with -(postInt-1) in hasKey because it crashed after the following change in calcDiversity:
if posInt<0 then pos=-posInt to access key[le-pos]. (from le-1 to 0)
It is a Debug profile, not a Release_debug as I thinked,
In fact, these are the g++ options (from a ps uax| grep g++)
-m64 -Wnon-virtual-dtor -Wno-long-long -ansi -Wundef -Wcast-align -Wchar-subscripts -Wall -W -Wpointer-arith -Wformat-security -fno-exceptions -DQT_NO_EXCEPTIONS -fno-check-new -fno-common -Woverloaded-virtual -fno-threadsafe-statics -fvisibility=hidden -Werror=return-type -fvisibility-inlines-hidden -g -O2 -fno-reorder-blocks -fno-schedule-insns -fno-inline -Wl,--enable-new-dtags
I've come to it by luck..the NOTE comment and looking at QBitArray documentation, because
I'm looking to fix my constant warning: mime type inode/directory .... not found. (not found because the files are deleted by some process).</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Using this way to build a for loop: for (const_iterator it=list.constBegin, end=list.constEnd ; it != end; ++it)
and replacing the count of bits with the QBitArray method for doing that.
callgrind says:
before: 2984 calls to constBegin, 0,00%. 2960531 calls to constEnd, 2.33%
after: 2921 calls to constBegin, 0,00%. 2921 calls to constEnd, 0.00%
before: calcDiversity, 55.83% (debug enabled)
after: calcDiversity, 14,46% (debug enabled)
buildsycoca is still not faster than light, but it is only a four lines patch.</pre>
