From cf5a8b489464d09dfdd7a48ce7c8b41d3c9bf819 Mon Sep 17 00:00:00 2001 From: Pengcheng Wang Date: Fri, 26 Apr 2024 16:59:12 +0800 Subject: [clang] Enable sized deallocation by default in C++14 onwards (#83774) Since C++14 has been released for about nine years and most standard libraries have implemented sized deallocation functions, it's time to make this feature default again. This is another try of https://reviews.llvm.org/D112921.
