536 * (3) received signal
537 *
538 * Detail:
539 * (1) called invalid address
540 * In this case, saved ip is invalid address.
541 * It needs to just save the address for the information,
542 * skip the frame, and restore the frame calling the
543 * invalid address from %rsp.
544 * The problem is how to check whether the ip is valid or not.
545 * This code uses mincore(2) and assume the address's page is
546 * incore/referenced or not reflects the problem.
547 * Note that High Sierra's mincore(2) may return -128.
548 * (2) read or write invalid address
549 * saved ip is valid. just restart backtracing.
550 * (3) received signal in user space
551 * Same as (2).
552 * (4) received signal in kernel
553 * In this case saved ip points just after syscall, but registers are
554 * already overwritten by kernel. To fix register consistency,
555 * skip libc's kernel wrapper.
556 * To detect this case, just previous two bytes of ip is "\x0f\x05",
557 * syscall instruction of x86_64.
