From f230df9af4012f9510de664b6d62b128e26a5861 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Sat, 16 Oct 2010 18:23:53 +0000 Subject: Add a MCObjectFormat class so that code common to all targets that use a single object format can be shared. This also adds support for mov zed+(bar-foo), %eax on ELF and COFF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116675 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/MC/MCObjectFormat.cpp | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 lib/MC/MCObjectFormat.cpp (limited to 'lib/MC/MCObjectFormat.cpp') diff --git a/lib/MC/MCObjectFormat.cpp b/lib/MC/MCObjectFormat.cpp new file mode 100644 index 0000000..07d361c --- /dev/null +++ b/lib/MC/MCObjectFormat.cpp @@ -0,0 +1,31 @@ +//===- lib/MC/MCObjectFormat.cpp - MCObjectFormat implementation ----------===// +// +// The LLVM Compiler Infrastructure +// +// This file is distributed under the University of Illinois Open Source +// License.
