From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/101870] std::lerp is missing Arithmetic overloads Date: Mon, 09 May 2022 16:40:16 +0000 [thread overview] Message-ID: <bug-101870-4-IIc3G8XiQm@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-101870-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101870 --- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jonathan Wakely <redi@gcc.gnu.org>: https://gcc.gnu.org/g:5ed333b0762d847ffb0096ba97e924188c766d69 commit r9-10059-g5ed333b0762d847ffb0096ba97e924188c766d69 Author: Jonathan Wakely <jwakely@redhat.com> Date: Thu Aug 12 17:35:25 2021 +0100 libstdc++: Add additional overload of std::lerp [PR101870] The [cmath.syn] p1 wording about additional overloads sufficient to handle any arithmetic types also applies to std::lerp. This adds a new overload of std::lerp that does the required promotions to support arguments of arbitrary arithmetic types. A new __promoted_t alias template is added, which the C++17 function templates std::hypot and std::lerp can use to avoid instantiating the __promote_3 class template. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: PR libstdc++/101870 * include/c_global/cmath (hypot): Use __promoted_t. (lerp): Add new overload accepting any arithmetic types. * include/ext/type_traits.h (__promoted_t): New alias template. * testsuite/26_numerics/lerp.cc: Moved to... * testsuite/26_numerics/lerp/1.cc: ...here. * testsuite/26_numerics/lerp/constexpr.cc: New test. * testsuite/26_numerics/lerp/version.cc: New test.
