Disabling “cast from pointer to smaller type uint32_t” error in Clang

Question

I\'m working on a school project that involves porting a large piece of C++ code on an experimental piece of hardware. Unfortunately, that hardware is 64-bit and the code contai

Answer 1

Save this piece of code as mycast.hpp and add -include mycast.hpp to your Makefile.

#include 

template
U Reinterpret_cast(T *x) {
    return (U)(uintptr_t)x;
}

template
U Reinterpret_cast(T &x) {
    return *(U*)&x;
}

#define reinterpret_cast Reinterpret_cast

They should do their job unless your code is too tricky.

Your strategy will not work for stack-allocated objects, be careful!! You can insert some debugging/logging logic to Reinterpret_cast if necessary.
