Hi harshit shah, I do not understand what you are trying to do. Do you want ints to be 64-bit on a 32-bit word architecture? Do you want pointers to be 64-bit on a 32-bit memory address architecture? Do you want both ints and pointers to be 64-bit on a 32-bit word & 32-bit memory address architecture? Either change will violate your platform's ABI. You wont be able to access system calls or the standard C library (or any other shared library), or use input or output, from the object code compiled from a non-ABI compliant compiler. You'll need to recompile any libraries you use. If you want to access system calls or standard C library, you'll need to write your own springboard routines*, probably in assembly, to convert from your non-ABI-compliant ints and pointers to ABI-compliant. As an alternative to consider, I recommend using a 64-bit platform. Probably a lot less work. Another alternative is to write your own virtual machine that uses 64-bit ints and pointers, and then write a cross-compiler to your virtual machine. Sincerely, --Eljay * springboard routines / thunk routines / trampoline routines ... I'm not sure what the correct terminology is.
