Just a quick note what changed: In ELF, .hash section (with DT_HASH dynamic tag pointing to it) is used during dynamic linking for symbol lookup, the dynamic linker for each symbol it needs to resolve uses that section to map it to a set of symbol indexes of possible symbol definitions. We wrote changes that introduce a new section (.gnu.hash, DT_GNU_HASH dynamic tag) that serves the same purpose, but is much more efficient (gives far fewer symbol definition candidates and uses far fewer cachelines).
Is this for speeding up building or does this speed up program startup? How much faster is using .gnu.hash over .hash? Just curious, n0dalus.
