CCPtool is an instrument used to determine calling conventions of c-like functions in binary files. It's simple to use and simple to embed as a part chain of commands or as a part of other code.
Capstone version >= 3.0.1
gcc version >= 4.8.5 supporting -std=c++1y
cd CCPtool && make && make install
Run CCPtool --help to get internal help.
CCPtool uses virtual addresses of functions provided to it to seek to functions in file to analyse.
CCPtool filename vaddr1 [vaddr2, ...]
For each address supplied it will print to stdout a line containing a word standing for the function's calling convention type.
