CPP_Analysis: A Analyzer of c or c++

The tool is built on ClangIR.

1. Build

CPP_Analysis depends on LLVM. So before building CPP_Analysis, LLVM should be build and add the find_package CMAKE_PREFIX_PATH.

1.1 Building LLVM

The important thing the following parameter: Add LLVM_ENABLE_PROJECTS="clang;mlir". Because we need to use clang frontend and mlir.

For instance, an command to build llvm could be:

cmake -DCMAKE_BUILD_TYPE=Debug
      -DLLVM_ENABLE_PROJECTS=clang;mlir
      -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE 
      -DCMAKE_C_COMPILER:FILEPATH=/usr/bin/clang
      -DCMAKE_CXX_COMPILER:FILEPATH=/usr/bin/clang++
      --no-warn-unused-cli 
      -S/Users/shuanglong/projects/llvm-project/llvm 
      -B/Users/shuanglong/projects/llvm-project/build 
      -G Ninja 
      path/to/cmakefile

Attention: The llvm now needs to change a little bit see Fix issues of ClangIR

1.2 Building CPP_Analysis

You can use the following command to compile CPP_Analysis project.

cmake -DCMAKE_BUILD_TYPE=Debug 
	  -DCMAKE_PREFIX_PATH=/path/to/llvm-project/build 
	  -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE 
	  -DCMAKE_C_COMPILER:FILEPATH=/usr/bin/clang 
	  -DCMAKE_CXX_COMPILER:FILEPATH=/usr/bin/clang++ 
	  --no-warn-unused-cli 
	  -S/Users/shuanglong/projects/CPP_ANALYSIS 
	  -B/Users/shuanglong/projects/CPP_Analysis/build 
	  -G Ninja

CMAKE_PREFIX_PATH must be the path to the llvm build directory you just compiled.
