Souper is a superoptimizer for LLVM IR. It uses an SMT solver to help identify missing peephole optimizations in LLVM's midend optimizers.
You will need a reasonably modern compiler toolchain. LLVM has instructions on how to get one for Linux: http://llvm.org/docs/GettingStarted.html#getting-a-modern-host-c-toolchain
You will also need CMake to build Souper and its dependencies, and the zstd library from your package manager or from Homebrew.
$buildtype is optional; it defaults to Release and may be set to any LLVM build type. $extra_cmake_flags is optional. It is passed to CMake.
Again, the build type is optional and defaults to Release. In any case it must match the build type used when compiling the dependencies.
Optionally run 'make check' to run Souper's test suite. To run the test suite under Valgrind, run 'make check LIT_ARGS="-v --vg --vg-leak"' instead. By default the solver is also run under Valgrind. This can be disabled by by adding --vg-arg=--trace-children-skip=/path/to/solver to LIT_ARGS.
Note that GCC 4.8 and earlier have a bug in handling multiline string literals. You should build Souper using GCC 4.9+ or Clang.
