From c5f28e2a05f2ebff09e1cd02a5faa84369c5c655 Mon Sep 17 00:00:00 2001 From: Kamil Rytarowski Date: Mon, 6 Feb 2017 17:55:02 +0000 Subject: Switch std::call_once to llvm::call_once Summary: The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms. This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.
