2019-01-11scons: added support of default Python installation on MacOSAndrea Mondelli
Recent MacOS versions are distributed with python 2.7. This version of python is sufficient to compile and run gem5. This patch allows to use the default python instead of the version provided by third-party tools (e.g., brew) The default MacOS LLDB debugger is linked against the default python installation, which conflicts with Python framework provided by third-party package systems. This patch removes the need of gem5 to have multiple python installations on MacOS, if not explicitly installed.

2017-06-06scons: Try to handle problems with gcc, lto and partial linking.Gabe Black
gcc has had a lot of problems with incremental linking and partial linking at the same time. Basically, the partial link assumes that it's the only link that's going to happen, and it converts weak external symbols into regular external symbols. Then when the real final link happens, those symbols are duplicated and the link fails. Versions of gcc 6 and greater add an option called -flinker-output which lets you tell the linker to do an incremental link. Unfortunately, other bugs make that fail, and so gcc 6 doesn't work either. Hopefully version 7 works better. A --force-lto option was added so that, when only one of lto and partial linking is available, you can switch from having partial linking to having lto.

2017-05-02python: Use PyBind11 instead of SWIG for Python wrappersAndreas Sandberg
Use the PyBind11 wrapping infrastructure instead of SWIG to generate wrappers for functionality that needs to be exported to Python. This has several benefits: * PyBind11 can be redistributed with gem5, which means that we have full control of the version used. This avoid a large number of hard-to-debug SWIG issues we have seen in the past. * PyBind11 doesn't rely on a custom C++ parser, instead it relies on wrappers being explicitly declared in C++. The leads to slightly more boiler-plate code in manually created wrappers, but doesn't doesn't increase the overall code size. A big benefit is that this avoids strange compilation errors when SWIG doesn't understand modern language features. * Unlike SWIG, there is no risk that the wrapper code incorporates incorrect type casts (this has happened on numerous occasions in the past) since these will result in compile-time errors. As a part of this change, the mechanism to define exported methods has been redesigned slightly. New methods can be exported either by declaring them in the SimObject declaration and decorating them with the cxxMethod decorator or by adding an instance of PyBindMethod/PyBindProperty to the cxx_exports class variable. The decorator has the added benefit of making it possible to add a docstring and naming the method's parameters. The new wrappers have the following known issues: * Global events can't be memory managed correctly. This was the case in SWIG as well.

The git hook installation script sometimes needs to create a hooks directory in the repository. Due to the cached state of the hooks directory, the build system tries to create it twice. The second mkdir operation leads to an error since the directory already exists. Fix this issue by clearing the cached state of the hooks directory after creating it.

2017-03-26scons: Collapse symlinks when installing git hooks.Gabe Black
When naively computing the relative path between the git hooks directory and a hook we want to install, that will generally start with a few ".." path components to work back out of the .git directory into the working directory.' If the hooks directory is actually a symlink, then following ".." directory entries won't get us back to where we came from, they'll take us to the actual parent directory of hooks. The relative path we computed would then try to go forward from this other directory using a path that would have worked in the working directory, hopefully going somewhere that doesn't exist, but potentially going to a totally unrelated file with the same relative path. To avoid this problem, we should expand any symlinks in both the hooks directory path, and the path to the hook script. That way, any ".." components will go where we'd expect them to, and the relative path will actually go from hooks to the script we expect.

2017-03-26scons: Use a relative symlink for git hooks more selectively.Gabe Black
If the hooks directory is a symlink, then there are at least two possible scenarios to consider when installing a hook which is itself a symlink. The first is that hooks is a relative symlink, and so is likely intended to stay in place relative to .git and the git working directory. In that case, it's ok for the symlinks inside of hooks to be relative to the working directory too, since they should also stay in place relatively speaking. The second situation is that the symlink is absolute. In that case, moving the git working directory will move the hook relative to the hook directory, and any relative symlink will become broken. In that case, the hook symlink needs to be absolute. The same logic likely applies to the .git directory itself, although I haven't run into a situation in practice where the .git directory is actually a symlink.

Trying to create a new symlink in its place without first removing the old one causes a build failure in these cases. If the hook doesn't "exist" but is still a link, that means it's actually a broken link and should be deleted by the hook installation function before any new symlink is created.

2016-05-09scons: Rewrite git style hook installerAndreas Sandberg
The SCons script currently assumes that .git is a proper directory with all git meta data. This isn't the case if the working directory was checked out using git worktrees.
