Expand description

Elementary operation in the unwind operations.

Variants

SaveRegister

Defines that a register is saved at the specified offset.

Fields of SaveRegister

reg: Reg

The saved register.

stack_offset: u32

The specified offset relative to the stack pointer.

RestoreRegister

Defines that a register is as defined before call.

Fields of RestoreRegister

reg: Reg

The restored register.

StackAlloc

The stack pointer was adjusted to allocate the stack.

Fields of StackAlloc

size: u32

Size to allocate.

StackDealloc

The stack pointer was adjusted to free the stack.

Fields of StackDealloc

size: u32

Size to deallocate.

SetFramePointer

The alternative register was assigned as frame pointer base.

Fields of SetFramePointer

reg: Reg

The specified register.

RestoreFramePointer

Restores a frame pointer base to default register.

RememberState

Saves the state.

RestoreState

Restores the state.

Aarch64SetPointerAuth

On aarch64 ARMv8.3+ devices, enables or disables pointer authentication.

Fields of Aarch64SetPointerAuth

return_addresses: bool

Whether return addresses (hold in LR) contain a pointer-authentication code.
