From ddb2455b5961eabcde56da66a61fd96600311c62 Mon Sep 17 00:00:00 2001 From: Mikhail Glushenkov Date: Mon, 2 Mar 2009 09:01:14 +0000 Subject: Reorganize llvmc code. Move the code from 'llvmc/driver' into a new CompilerDriver library, and change the build system accordingly. Makes it easier for projects using LLVM to build their own llvmc-based drivers. Tested with objdir != srcdir. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65821 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/llvmc/driver/Main.cpp | 126 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 126 insertions(+) create mode 100644 tools/llvmc/driver/Main.cpp (limited to 'tools/llvmc/driver/Main.cpp') diff --git a/tools/llvmc/driver/Main.cpp b/tools/llvmc/driver/Main.cpp new file mode 100644 index 0000000..16b91a8 --- /dev/null +++ b/tools/llvmc/driver/Main.cpp @@ -0,0 +1,126 @@ +//===--- Main.cpp - The LLVM Compiler Driver -------------------*- C++ -*-===// +// +// The LLVM Compiler Infrastructure +// +// This file is distributed under the University of Illinois Open +// Source License.
