About Aladdin's Input

[xyzsam]

When you write a program for Aladdin, there are two parts: the kernel that Aladdin converts into an accelerator model, and all the surrounding code (e.g. main, reading from input files, etc). The kernel must be C, but the surrounding code can be C++. Example:

extern "C" {
void my_kernel(int* array, size) {
  // This is the function that gets traced by LLVM-Tracer.
  // this MUST be C
}
}
int main() {
  // Surrounding code can use C++.
  std::vector<int> data{1,2,3,4};
  my_kernel(data.data(), data.size());
}

Note the extern "C" block - that ensures C-style linkage, so you don't need to worry about C++ name mangling.
