}Expand description
Elementary operation in the unwind operations.
Variants
Defines that a register is saved at the specified offset.
Fields of SaveRegister
Defines that a register is as defined before call.
The stack pointer was adjusted to allocate the stack.
Fields of StackAlloc
size: u32Size to allocate.
The stack pointer was adjusted to free the stack.
Fields of StackDealloc
size: u32Size to deallocate.
The alternative register was assigned as frame pointer base.
Restores a frame pointer base to default register.
Saves the state.
Restores the state.
On aarch64 ARMv8.3+ devices, enables or disables pointer authentication.
Fields of Aarch64SetPointerAuth
return_addresses: boolWhether return addresses (hold in LR) contain a pointer-authentication code.
