Struct lief::pe::exception_aarch64::Packed

pub struct Packed<'a> { /* private fields */ }

This structure represents a packed AArch64 exception entry.

An excepted entry can be packed if the unwind data fit in 30 bits

Implementations

impl Packed<'_>

pub fn frame_size(&self) -> u8

Size of the allocated stack

pub fn reg_I(&self) -> u8

Number of non-volatile INT registers (x19-x28) saved in the canonical stack location.

pub fn reg_F(&self) -> u8

Number of non-volatile FP registers (d8-d15) saved in the canonical stack location

pub fn H(&self) -> u8

1-bit flag indicating whether the function homes the integer parameter registers (x0-x7) by storing them at the very start of the function. (0 = doesn’t home registers, 1 = homes registers).

pub fn CR(&self) -> u8

Flag indicating whether the function includes extra instructions to set up a frame chain and return link.
