Clang and Ghidra integrations for analysis

I've been working on some tools to facilitate using Ghidra's decompiler and Clang's front-end plugins to help provide some functional code analysis. This folder contains some of this work.

I borrowed DecompileToC.java from the work provided in the following repository:

• https://github.com/h4sh5/ghidra-headless-decompile

Compilation of Clang plugin

The source code in StmtParser.cpp is intended to be compiled as a front-end plugin for clang. The following is an example of compiling/linking it:

clang++ -g2 -DPIC -fpic -shared -o StmtParser.so StmtParser.cpp `llvm-config --cxxflags`

Running

To use this plugin with clang (doesn't try to compile, but instead just pre-processes and parses the source with -E):

clang -cc1 -load ./StmtParser.so -plugin parse-stmts -E your_source_code.c `llvm-config --cflags` > sigs.txt

The above command will write the list of signatures and function call relationships to sigs.txt, while writing any parsing errors or warnings to stderr.
