Cleanup this test a bit. Use simpler names and remove unnecessary fields. llvm-svn: 220498 2014-10-24 03:23:42 +08:00			`; RUN: not llvm-link %s %p/Inputs/comdat8.ll -S -o - 2>&1 \| FileCheck %s`

IR: Add COMDATs to the IR This new IR facility allows us to represent the object-file semantic of a COMDAT group. COMDATs allow us to tie together sections and make the inclusion of one dependent on another. This is required to implement features like MS ABI VFTables and optimizing away certain kinds of initialization in C++. This functionality is only representable in COFF and ELF, Mach-O has no similar mechanism. Differential Revision: http://reviews.llvm.org/D4178 llvm-svn: 211920 2014-06-28 02:19:56 +08:00
