prelink modifies binary and library to ... prelink ;-) them. during the
days of kde 3 I noticed a significant improvement in loading time of

almost the same thing [ref. needed]
A long time back(seems like eternity) I wrote a small post describing GNU
hash options in linker at http://dhoomketu.net.in/node/34.
I cannot find the spec file in the arch GCC package anymore but the
binaries
do contain GNU hash section. Just run readelf on any binary, like
/bin/ls and
look for .gnu.hash.
If the gcc package forces linker option to be GNU hash style only(I
don't know
how to verify this on arch), it could achieve the speed improvement
and reduce
the binary size somewhat as well.
I guess most of that is already used by now except for forcing the GNU
hash-
style only.
The gcc package uses --hash-style=both by default, but the default
LDFLAGS for makepkg overrides this with --hash-style=gnu

Well, I'm bumping this thread, but I have a doubt. When we run prelink,
prelinking is permanent or has to be done at every boot ?
