[LLVMdev] convert integer to double "uitofp" or "sitofp" ?
Hello,
As I understand, in LLVM IR it cannot be determined whether a register of type int is signed or unsigned.
If one wants to convert an integer to a double, which instruction should be used: "uitofp" or "sitofp" ?
We track the values taken by all load instructions and we process them using a function. If the value is a pointer, we use int64 as the type of the function
