From 0d91c0b519e0053931bf9502ebeaf44d397812f0 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Sun, 28 Oct 2012 21:34:43 +0000 Subject: Remove TargetELFWriterInfo. All the credit goes to Jan Voung for noticing it was dead! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166902 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/TargetELFWriterInfo.h | 121 ------------------------------ include/llvm/Target/TargetMachine.h | 6 -- 2 files changed, 127 deletions(-) delete mode 100644 include/llvm/Target/TargetELFWriterInfo.h (limited to 'include') diff --git a/include/llvm/Target/TargetELFWriterInfo.h b/include/llvm/Target/TargetELFWriterInfo.h deleted file mode 100644 index 5e48629..0000000 --- a/include/llvm/Target/TargetELFWriterInfo.h +++ /dev/null @@ -1,121 +0,0 @@ -//===-- llvm/Target/TargetELFWriterInfo.h - ELF Writer Info -----*- C++ -*-===// -// -// The LLVM Compiler Infrastructure -// -// This file is distributed under the University of Illinois Open Source -// License.
