From c432c8f856e0bd84de980a9d9bb2d31b06fa95b1 Mon Sep 17 00:00:00 2001 From: Zachary Turner Date: Wed, 28 Oct 2015 17:43:26 +0000 Subject: Move lldb/test to lldb/packages/Python/lldbsuite/test. This is the conclusion of an effort to get LLDB's Python code structured into a bona-fide Python package. This has a number of benefits, but most notably the ability to more easily share Python code between different but related pieces of LLDB's Python infrastructure (for example, `scripts` can now share code with `test`). llvm-svn: 251532 --- .../test/functionalities/register/main.cpp | 51 ++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 lldb/packages/Python/lldbsuite/test/functionalities/register/main.cpp (limited to 'lldb/packages/Python/lldbsuite/test/functionalities/register/main.cpp') diff --git a/lldb/packages/Python/lldbsuite/test/functionalities/register/main.cpp b/lldb/packages/Python/lldbsuite/test/functionalities/register/main.cpp new file mode 100644 index 00000000000..876dd0833e5 --- /dev/null +++ b/lldb/packages/Python/lldbsuite/test/functionalities/register/main.cpp @@ -0,0 +1,51 @@ +//===-- main.cpp ------------------------------------------------*- C++ -*-===// +// +// The LLVM Compiler Infrastructure +// +// This file is distributed under the University of Illinois Open Source +// License.
