You can declare local variables in either registers or memory (the stack). So a `var` statement has two forms: - - `var x/eax: int <- copy 0` - - `var x: int` + - Living in a register, e.g. `var x/eax: int <- copy 0` defines `x` which + lives in `eax`. + - Living in memory, e.g. `var x: int` defines `x` on the stack. Variables in registers must be initialized. Variables on the stack are implicitly zeroed out. |
