I've estimated this as taking about two person-years of work (that is, two person-years of work for someone with extensive experience in GCC development). https://gcc.gnu.org/legacy-ml/gcc-patches/2010-06/msg02675.html While there have, for example, been various conversions of target macros to hooks, and other such similar changes, since then, I don't think anything fundamentally changes the basic estimate. -- Joseph S.
