However the situation seems is little more complicated than my expect at beginning...:P Anyway, I still think it's fine to accept that to me *IF* bintuils part has landed, but only limited to -march support, no further things for GCC 14 like intrinsic and auto vectorizer stuff for t-head vector (or vector 0.7).
