Implementations

impl X64Register

pub fn to_index(&self) -> RegisterIndex

Returns the index of the register.

pub fn from_dwarf_regnum(x: u16) -> Option<X64Register>

Converts a DWARD regnum to X64Register.

pub fn prefix_mov_to_stack(&self) -> Option<&'static [u8]>

Returns the instruction prefix for movq %this_reg, ?(%rsp).

To build an instruction, append the memory location as a 32-bit offset to the stack pointer to this prefix.
