This avoids unnecessary instantiations of std::numeric_limits or inclusion of <limits> when a more lightweight alternative would work. Some uses can be replaced with __gnu_cxx::__int_traits and some can just use size_t(-1) directly where SIZE_MAX is needed. libstdc++-v3/ChangeLog: * include/bits/regex.h: Use __int_traits<int> instead of std::numeric_limits<int>. * include/bits/uniform_int_dist.h: Use __int_traits<T>::__max instead of std::numeric_limits<T>::max(). * include/bits/hashtable_policy.h: Use size_t(-1) instead of std::numeric_limits<size_t>::max(). * include/std/regex: Include <ext/numeric_traits.h>. * include/std/string_view: Use typedef for __int_traits<int>. * src/c++11/hashtable_c++0x.cc: Use size_t(-1) instead of std::numeric_limits<size_t>::max(). * testsuite/std/ranges/iota/96042.cc: Include <limits>. * testsuite/std/ranges/iota/difference_type.cc: Likewise. * testsuite/std/ranges/subrange/96042.cc: Likewise.
