From 387e5ec502096dcd3564889b238e6442112a9784 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Tue, 31 Aug 2004 17:43:29 +0000 Subject: Add a new abstraction, SysConfig for platform independent system configuration calls. Right now this just contains PreventCoreFiles so that bugpoint can by platform independent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16124 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/System/Unix/SysConfig.cpp | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 lib/System/Unix/SysConfig.cpp (limited to 'lib/System/Unix/SysConfig.cpp') diff --git a/lib/System/Unix/SysConfig.cpp b/lib/System/Unix/SysConfig.cpp new file mode 100644 index 0000000000..a1c037639b --- /dev/null +++ b/lib/System/Unix/SysConfig.cpp @@ -0,0 +1,35 @@ +//===- SysConfig.cpp - Generic UNIX System Configuration --------*- C++ -*-===// +// +// The LLVM Compiler Infrastructure +// +// This file was developed by Reid Spencer and is distributed under the +// University of Illinois Open Source License.
