From 4f48470d8407666c88c8fa704b8719a6dfe98250 Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Tue, 31 Aug 2004 17:43:29 +0000 Subject: [PATCH] Add a new abstraction, SysConfig for platform independent system configuration calls. Right now this just contains PreventCoreFiles so that bugpoint can by platform independent. llvm-svn: 16124 --- llvm/lib/System/AIX/SysConfig.cpp | 27 +++++++++++++++++++++ llvm/lib/System/Cygwin/SysConfig.cpp | 27 +++++++++++++++++++++ llvm/lib/System/Darwin/SysConfig.cpp | 27 +++++++++++++++++++++ llvm/lib/System/Linux/SysConfig.cpp | 27 +++++++++++++++++++++ llvm/lib/System/SunOS/SysConfig.cpp | 27 +++++++++++++++++++++ llvm/lib/System/SysConfig.cpp | 29 +++++++++++++++++++++++ llvm/lib/System/Unix/SysConfig.cpp | 35 ++++++++++++++++++++++++++++ llvm/lib/System/Unix/Unix.h | 1 + 8 files changed, 200 insertions(+) create mode 100644 llvm/lib/System/AIX/SysConfig.cpp create mode 100644 llvm/lib/System/Cygwin/SysConfig.cpp create mode 100644 llvm/lib/System/Darwin/SysConfig.cpp create mode 100644 llvm/lib/System/Linux/SysConfig.cpp create mode 100644 llvm/lib/System/SunOS/SysConfig.cpp create mode 100644 llvm/lib/System/SysConfig.cpp create mode 100644 llvm/lib/System/Unix/SysConfig.cpp diff --git a/llvm/lib/System/AIX/SysConfig.cpp b/llvm/lib/System/AIX/SysConfig.cpp new file mode 100644 index 000000000000..53b4b0c8658b --- /dev/null +++ b/llvm/lib/System/AIX/SysConfig.cpp @@ -0,0 +1,27 @@ +//===- AIX/SysConfig.cpp - AIX SysConfig Implementation ---------*- C++ -*-===// +// +// The LLVM Compiler Infrastructure +// +// This file was developed by Reid Spencer and is distributed under the +// University of Illinois Open Source License.
