1 # This file defines a tcl proc to assist with testing the llvm2cpp. There are
2 # no llvm2cpp specific test cases. Instead, it utilizes all the existing test
3 # cases and makes sure llvm2cpp can run them. The basic idea is that we find
4 # all the LLVM Assembly (*.ll) files, run llvm2cpp on them to generate a C++
5 # program, compile those programs, run them and see if what they produce matches
6 # the original input to llvm2cpp.
