Ah, I even participated then ;-) AFAI understand gcc-5 should compile faster? And generate faster code in some cases? looking at genlop -t I can't really spot speedups in the last months. With gcc-5.2.0 as I have here right now: 5.2.0(5.2)^s(20:52:29 18.07.2015)(cxx fortran multilib nls openmp sanitize -altivec -awt -cilk -debug -doc -fixed-point -gcj -go -graphite -hardened -libssp -multislot -nopie -nossp -nptl -objc -objc++ -objc-gc -regression-test -vanilla) ... does it use this new stuff anyway, do we need a specific USE-flag enabled (I can't spot it, looking for something like "acc" or "rdma" ;-)), do we need specific CFLAGS .. ? just curious. btw: might be a projection but for some times back I noticed that my gentoo installation got somehow "snappier" in a way. Might relate to my rebuilding with gcc-5.x (and overall improvement of hundreds of packages, sure).
