AMD64PtraceRegs is the struct used by the freebsd kernel to return the general purpose registers for AMD64 CPUs. source: sys/x86/include/reg.h

type AMD64Registers

type AMD64Registers struct {
	Regs     *AMD64PtraceRegs
	Fpregs   []proc.Register
	Fpregset *amd64util.AMD64Xstate
	Fsbase   uint64
	// contains filtered or unexported fields
}

AMD64Registers implements the proc.Registers interface for the native/freebsd backend and core/freebsd backends, on AMD64.

func NewAMD64Registers

func NewAMD64Registers(regs *AMD64PtraceRegs, fsbase uint64, loadFpRegs func(*AMD64Registers) error) *AMD64Registers

func (*AMD64Registers) BP

func (r *AMD64Registers) BP() uint64

func (*AMD64Registers) Copy

func (r *AMD64Registers) Copy() (proc.Registers, error)

Copy returns a copy of these registers that is guaranteed not to change.

func (*AMD64Registers) GAddr

func (r *AMD64Registers) GAddr() (uint64, bool)

GAddr returns the address of the G variable if it is known, 0 and false otherwise.

func (*AMD64Registers) Get

func (r *AMD64Registers) Get(n int) (uint64, error)

Get returns the value of the n-th register (in x86asm order).

func (*AMD64Registers) PC

func (r *AMD64Registers) PC() uint64

PC returns the value of RIP register.

func (*AMD64Registers) SP

func (r *AMD64Registers) SP() uint64

SP returns the value of RSP register.

func (*AMD64Registers) Slice

func (r *AMD64Registers) Slice(floatingPoint bool) ([]proc.Register, error)

Slice returns the registers as a list of (name, value) pairs.

func (*AMD64Registers) TLS

func (r *AMD64Registers) TLS() uint64

TLS returns the address of the thread local storage memory segment.
