    At the LLVM level, size_t doesn’t exist. It is a construct for the benefit of the developer that is typedef’d to a native type. The native types have a fixed size for the target architecture and that is how the compiler represents them in LLVM bit code. So on x86, size_t might by viewed by the front end as unsigned long, which it then writes to LLVM as i32 (since LLVM assembly doesn’t have an unsigned type).
