532 * (3) received signal
533 *
534 * Detail:
535 * (1) called invalid address
536 * In this case, saved ip is invalid address.
537 * It needs to just save the address for the information,
538 * skip the frame, and restore the frame calling the
539 * invalid address from %rsp.
540 * The problem is how to check whether the ip is valid or not.
541 * This code uses mincore(2) and assume the address's page is
542 * incore/referenced or not reflects the problem.
543 * Note that High Sierra's mincore(2) may return -128.
544 * (2) read or write invalid address
545 * saved ip is valid. just restart backtracing.
546 * (3) received signal in user space
547 * Same as (2).
548 * (4) received signal in kernel
549 * In this case saved ip points just after syscall, but registers are
550 * already overwritten by kernel. To fix register consistency,
551 * skip libc's kernel wrapper.
552 * To detect this case, just previous two bytes of ip is "\x0f\x05",
553 * syscall instruction of x86_64.
