2017-05-16x86: Fix the multiplication microops.Gabe Black
If the operands were 64 bit, an intermediate calculation could lose a carry bit. This change rearranges that intermediate calculation if the operand width is large, and reworks the microop implementation in general in an attempt to make it easier to understand.

2017-05-16python: Add a helper function to create Python eventsAndreas Sandberg
Add a helper function, m5.event.create(), to create events from Python. This function takes a callable Python object (e.g., a function) as an argument and optionally a priority as a keyword argument. This function was accidentally dropped from the public API when switching to PyBind.

2017-05-15cpu: fix problem with forwarding and locked loadAlec Roelke
If a (regular) store is followed closely enough by a locked load that overlaps, the LSQ will forward the store's data to the locked load and never tell the cache about the locked load. As a result, the cache will not lock the address and all future store-conditional requests on that address will fail. This patch fixes that by preventing forwarding if the memory request is a locked load and adding another case to the LSQ forwarding logic that delays the locked load request if a store in the LSQ contains all or part of the data that is requested. [Merge second and last if blocks because their bodies are the same.] Change-Id: I895cc2b9570035267bdf6ae3fdc8a09049969841 Reviewed-on: https://gem5-review.googlesource.com/2400 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Reviewed-by: Nikos Nikoleris <nikos.nikoleris@arm.com> Reviewed-by: Tony Gutierrez <anthony.gutierrez@amd.com> Maintainer: Jason Lowe-Power <jason@lowepower.com>

2017-05-12misc: Make the remote GDB stub more resilient to bad connections.Gabe Black
Currently, if the remote gdb stub fails to read a byte from an incoming packet because the connection has been dropped, the read call will return anyway and the calling code will have no way to know something bad happened. It might reattempt the read over and over again waiting for some particular byte, doomed to never make forward progress. This change modifies the remote GDB code so that if a read or write call fails, it will instead detach from the debugger and continue. Before this change, When simulating a port scan, ie connecting to the debugger port and then immediately dropping the connection using this command: nc -v -n -z -w 1 127.0.0.1 7000 gem5 would enter the previously described death spiral. After it, gem5 detaches from the bad connection and resumes execution. Subsequently attaching with gdb was successful. This code is written in a C centric style, and would benefit from some refactoring.

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.

2017-05-01scons: Remove the SPAWN hack added earlier.Gabe Black
A previous change forced scons to spawn child processes by exec-ing it directly rather than going through the shell because the command line length would be too long for the shell to handle. Now that incremental linking should keep the command line lengths more under control, that change should no longer be necessary.

2017-05-01scons: Group Source-s based on what SConscript included them.Gabe Black
The groups won't be perfectly balanced or optimally planned, but this requires no thought and breaks the object files down into a reasonable number of reasonably sized groups.

2017-05-01scons: Put Source objects in groups and partially link them.Gabe Black
The groups will be linked together into intermediate partially linked object files. Right now the hierarchy is assumed to be flat, but with some effort it could be extended to allow truly hierarchical linking.

2017-04-25misc: Add MAINTAINERS fileJason Lowe-Power
This file defines all of the commit keywords used for gem5 commits and the maintainter(s) for each of these keywords. This patch introduces a number of new keywords, and changes to previous keywords. The new keywords better follow gem5's directory structure and are more extensible. Currently, most keywords do not have a maintainer. More maintainers will be added as more people volunteer to be maintainers. This patch also updates the CONTRIBUTING.md file to point to this file instead of listing the keywords separately. When this file is committed the wiki will also be updated accordingly.
