Hi,
the attached patch tries to optimize a bit the lookup process
into the dynamic linker postponing the string comparisons as late
as possible.
At the moment I have not figures/benchmarks to be shown; hope to produce
some data in the future.
Regards,
Carmelo
Do string comparisos as late as possible during symbol lookup.
