Alexey,
Hopefully the gcc developers might manage to get the LTO
branch merged for gcc 4.4. They have some benchmarks in figure 7
of the article "Interprocedural optimization framework in GCC"
which suggests that whole program optimizations currently can
yield as much as ~30% speed improvements. If that gets coupled
with the new scheduler replacing haifa in gcc 4.4, it certainly
would be a nice release. My understanding was that Apple was
unlikely to upgrade the version of their gcc until 4.4 anyway.
