Specious - A SPEC CPU2006 benchmarks cmake harness

Introduction

This is a CMake build harness for the SPEC CPU2006.

The actual source files for each benchmark are not included, since they are distributed under a non-free/restrictive license.

Features

• Building of all C/C++ programs of the suite
• Out-of-source builds thanks to cmake
• Optional capability to create LLVM bitcode files thanks to llvm-ir-cmake-utils and LLVM opt pass pipelines (see the config/pipelines subdirectory).
• Capability to configure and build any desired subset of the programs by using the corresponding configuration (see the files in the config subdirectory).

Requirements

• cmake 3.0.0 or later
• a sensible C/C++ compiler

How to use

1. git clone --recursive this repo and also have available the benchmark source.
2. Create symlinks to the src subdirectory of each benchmark program. This can be automated with the relevant script found in the utils/scripts/source_tree subdirectory of this repo, for example:

create-symlink-bmk-subdir.sh -c suite_all.txt -s [path-to]/CPU2006/ -t [path-to]/specious/CPU2006 -l src

3. Create a directory for an out-of-source build and cd into it.
4. Run cmake and cmake --build . with that appropriate options. For examples on the various options have a look at the build scripts (provided for convenience) located in the utils/scripts/source_tree subdirectory.
5. Optionally, you can install the benchmarks by

cmake -DCMAKE_INSTALL_PREFIX=[path-to-install] -P cmake_install.cmake

Omitting CMAKE_INSTALL_PREFIX will use the ../install/ directory relative to the build directory.
