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).
