Does anybody have some benchmarks or links to articles that compare
this for different compiler implementations?
I would especially like to see if it is usefull on MSVC, Intel 9.0 C
and gcc.
Also what is about the effect of "interprocedural optimization".
All my use cases are 98% integer performance dominated. Currently i
only use -O2 or -O3 for MSVC and gcc but i would really like to now if
it is worth to spend time on optimization (which means that i would
see a 20% improvement by this two kinds of optimizations).
