Created stat group CommitCPUStats in BaseCPU and moved stats from the simple cpu model. The stats moved from SImpleCPU are numCondCtrlInsts, numFpInsts, numIntInsts, numLoadInsts, numStoreInsts, numVecInsts. Moved committedControl of MinorCPU to BaseCPU::CommittedCPUStats. In MinorCPU, this stat was a 2D vector, where the first dimension is the thread ID. In base it is now a 1D vector that is tied to a thread ID via the commitStats vector. The committedControl stat vector in CommitCPUStats is updated in the same way in all CPU models. The function updateComCtrlStats will update committedControl and the CPU models will call this function instead of updating committedControl directly. This function takes a StaticInstPtr as input, which Simple, Minor, and O3 CPU models are able to provide. Removed stat "branches" from O3 commit stage. This stat duplicates BaseCPU::CommittedCPUStats::committedControl::IsControl. O3 commit stats floating, integer, loads, memRefs, vectorInstructions are replaced by numFpInsts, numIntInsts, numLoadInsts, numMemRefs, numVecInsts from BaseCPU::CommitCPUStats respectively. Implemented numStoreInsts from BaseCPU::commitCPUStats for O3 commit stage.

This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of these tools. Once you have all dependencies resolved, type 'scons build/<CONFIG>/gem5.opt' where CONFIG is one of the options in build_opts like ARM, NULL, MIPS, POWER, SPARC, X86, Garnet_standalone, etc. This will build an optimized version of the gem5 binary (gem5.opt) with the the specified configuration. See http://www.gem5.org/documentation/general_docs/building for more details and options. The main source tree includes these subdirectories: - build_opts: pre-made default configurations for gem5 - build_tools: tools used internally by gem5's build process. - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - include: include files for use in other programs - site_scons: modular components of the build system - src: source code of the gem5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you may need compiled system firmware, kernel binaries and one or more disk images, depending on gem5's configuration and what type of workload you're trying to run. Many of those resources can be downloaded from http://resources.gem5.org, and/or from the git repository here: https://gem5.googlesource.com/public/gem5-resources/ If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
