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.

2017-04-18x86: fixed branching() computation for branch uopsSanti Galan
When a branch micro-op belongs to a flow and the micro-op does not change the nPC and just updates the nuPC (like a 'rep movs' flow), branching() function always returns not-taken no matter actual micro-branch outcome. Provided fix adds to the equation nuPC attribute checking since these kind of branch micro-op only updates that pointer. This issue has been found while debugging the performance of a copy-loop implemented with memcopy function. Without the fix, 'rep movss' internal micro-branch was always predicted as not-taken causing an squash event after every branch micro-branch execution. Using the provided test, branch mispredition went from 1922 without the fix to 7. Change-Id: I1bcbefae26aef47e3135817ef99b53d0ea0a98fa

This patch fixes a bug where increasing the mmap region too much causes it to run into already-allocated memory, which causes gem5 to fail an assertion. Previously, the stack was incorrectly set up such that the end of the mmap region and the top of the stack were the same address and both would grow downward. With this patch, the top of the stack has been separated from the end of mmap and moved up, and the mmap region now grows upward instead of downward.

2017-04-05scons: Fix hook installation error caused by stale cacheAndreas Sandberg
Due to the way SCons caches some file system state internally, it sometimes "remembers" that a file or directory didn't exist at some point. 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.
