Wasm makes no distinction between signed and unsigned integers as variables, only calling them integers. The relevant operations are split between signed and unsigned. https://webassembly.github.io/spec/core/appendix/index-instr... See how there's only i32.load and i32.eq, but there's i32.lt_u and i32.lt_s. Loading bits from memory or comparing them is the same operation bit for bit for each of signed and unsigned. However, less than requires knowing the desired signess, and is split between signed and unsigned. |
