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