[PATCH] D112921: [clang] Enable sized deallocation by default in C++14 onwards

[Konrad Wilhelm Kleine via Phabricator via cfe-commits]

kwk added a comment.

You've disabled sized deallocation in some tests by providing `-fno-sized-deallocation `. I admit I haven't looked at those tests in detail but I would like to understand if those tests would otherwise fail. If they fail, is there work that needs to be done later to make them work again?



================
Comment at: clang/lib/Driver/ToolChains/Clang.cpp:6403
 
-  // -fsized-deallocation is off by default, as it is an ABI-breaking change for
-  // most platforms.
-  if (Args.hasFlag(options::OPT_fsized_deallocation,
-                   options::OPT_fno_sized_deallocation, false))
-    CmdArgs.push_back("-fsized-deallocation");
+  // -fsized-deallocation is on by default in C++14 onwards and otherwise off
+  // by default.

@rjmccall mentioned [here](https://reviews.llvm.org/D8467#3125570) that 

> Apple would like this to only be enabled conditionally based on deployment target.

Is this considered at all?
