Struct RegisterContext 

pub struct RegisterContext {
    pub cpu_type: CpuType,
    pub is_64_bit: bool,
    /* private fields */
}

Register context holding register values indexed by DWARF register number.

Supports ARM64 and x86_64 DWARF register maps.

Fields

cpu_type: CpuType

is_64_bit: bool

Implementations

impl RegisterContext

pub fn new(cpu_type: CpuType) -> Self

Creates a new empty register context.

pub fn pc(&self) -> Option<u64>

Gets the program counter.

pub fn sp(&self) -> Option<u64>

Gets the stack pointer.

pub fn fp(&self) -> Option<u64>

Gets the frame pointer.

pub fn lr(&self) -> Option<u64>

Gets the link register (ARM64 only, returns None for x86_64).

pub fn get(&self, dwarf_reg: u16) -> Option<u64>

Gets a register by DWARF number.

pub fn set(&mut self, dwarf_reg: u16, value: u64)

Sets a register by DWARF number.

pub fn clear(&mut self, dwarf_reg: u16)

Clears a register by DWARF number.

pub fn set_pc(&mut self, value: u64)

Sets the program counter.

pub fn set_sp(&mut self, value: u64)

Sets the stack pointer.

pub fn set_fp(&mut self, value: u64)

Sets the frame pointer.

pub fn clear_volatile(&mut self)

Clears all volatile registers, keeping only non-volatile ones + SP + PC.

pub fn from_thread_state(state: &ThreadState, cpu_type: CpuType) -> Option<Self>

Converts from the existing ThreadState type used by CrashRustler.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RegisterContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result
