The standard only requires that _Size can be converted to an integral type, not that it can be used for arithmetic. Add a new set of __size_to_integer helper functions to do the conversion (which will be ambiguous if there is no one conversion that is better than any others). Also add tests for DR 426 which requires these algorithms and search_n to handle negative values of n. PR libstdc++/87982 * include/bits/stl_algo.h (generate_n): Convert _Size parameter to an integral type. * include/bits/stl_algobase.h (__size_to_integer): New overloaded functions to convert a value to an integral type. (__fill_n_a, __fill_n_a): Assert that __n is already an integral type. (fill_n): Convert _Size parameter to an integral type. * testsuite/25_algorithms/fill_n/dr426.cc: New test. * testsuite/25_algorithms/generate_n/87982.cc: New test. * testsuite/25_algorithms/generate_n/dr426.cc: New test.
