[syscall_linux,go] doesn't have Ptrace API support for ARM64 architecture

[oss...@puresoftware.com]

Hi,

I am working on delve (go debugger)  to provide support for ARM64 platform but  syscall_linux,go doesn't support ARM64 platform.

for getting reg values through Ptrace, we added following code in syscall_linux,go ..

ptrace(PTRACE_GETREGSET, pid, uintptr(elf.NT_PRSTATUS), uintptr(unsafe.Pointer(&iovec)))

can anyone suggest if i need to add support for ARM64 or is there any other method to get DWARF values on ARM64 platform ..

The syscall package is more or less frozen. Look at
golang.org/x/sys/unix instead, which does have the function
PtraceGetRegsArm64.
