John Ryland and I did some extra-work on objprelink.
Overview, explanations, details and benchmarks can be found in:
http://objprelink.sourceforge.net/objprelink.html
Summary of the conclusions:
- Recent binutils have been improved and now offer
performance similar to the old version of objprelink.
In fact, the new binutils and the old objprelink
are two different ways to achieve the same
complexity reduction.
- A new version, objprelink2, gives a new runtime link speedup.
But it no longer translate into improved KDE responsiveness
because the runtime linker delay is now a small component
of the application startup time.
I do not suggest using objprelink2 unless
your linux box lacks the improved binutils.
See <http://objprelink.sourceforge.net/> to check.
Be warned that objprelink is not a production tool.
This is more a research tool whose ideas, hopefully,
might be useful to others.
I also suggest removing the --enable-objprelink from
the KDE configure. Those who need objprelink will
use objprelink2 and will not need this option.
