Debug Info: Support DW_AT_calling_convention on composite types. This implements the DWARF 5 feature described at http://www.dwarfstd.org/ShowIssue.php?issue=141215.1 This allows a consumer to understand whether a composite data type is trivially copyable and thus should be passed by value instead of by reference. The canonical example is being able to distinguish the following two types: // S is not trivially copyable because of the explicit destructor. struct S { ~S() {} }; // T is a POD type. struct T { ~T() = default; }; This patch adds two new (DI)flags to LLVM metadata: TypePassByValue and TypePassByReference. <rdar://problem/36034922> Differential Revision: https://reviews.llvm.org/D41743 llvm-svn: 321844 2018-01-05 01:13:37 +00:00			`; RUN: not opt -S < %s 2>&1 \| FileCheck %s`
