Some notation for describing statement forms:
|
||||
- `var/reg` indicates a variable in some register. Sometimes we require a
|
||||
variable in a specific register, e.g. `var/eax`.
|
||||
- `var/xreg` indicates a variable in some floating-point register.
|
||||
- `var` without a `reg` indicates either a variable on the stack or
|
||||
dereferencing a variable in a (non-floating-point) register: `*var/reg`
|
||||
dereferencing a variable in a (non-floating-point) register: `*var/reg`.
|
||||
- `n` indicates a literal integer. There are no floating-point literals.
