Some standard algorithms fail to compile when size_t or ptrdiff_t is narrower than int. The __lg helper function is ambiguous if ptrdiff_t is short or __int20, so replace it with a function template that works for those types as well as signed/unsigned int/long/long long. The helpers for stable_sort perform arithmetic on size values and assume the types won't change, which isn't true if the type promotes to int. libstdc++-v3/ChangeLog: PR libstdc++/108221 * include/bits/stl_algobase.h (__lg): Replace six overloads with a single function template for all integer types. * include/bits/stl_algo.h (__merge_adaptive_resize): Cast arithmetic results back to _Distance. |
