How to Build

• make sure clang/clang++ is in your $PATH
• mkdir my-build-dir
• optionally mkdir my-install-dir
• [path to repo]/utils/build.sh [path torepo]/ [path to installation dir]
• cd my-build-dir
• make
• optionally make install

How to execute

Using opt

• make sure LLVM's opt is in your $PATH
• opt -load [path to plugin]/libLLVMSimplifyLoopExitsFront.so -simplify-loop-exits-front foo.bc -o foo.out.bc

Using clang

• make sure LLVM's clang is in your $PATH
• clang -Xclang -load -Xclang [path to plugin]/libLLVMSimplifyLoopExitsFront.so foo.c -o foo

Requirements

• Built and executed with:
  • LLVM 3.7.0
  • LLVM 3.8.0

Notes

• When the build script uses LLVM's cmake utility functions the lib shared library prefix is omitted
