_ [CPU][アーキテクチャ][NetBSD][MACHINE_ARCH]MACHINE_ARCH とは

MACHINE_ARCH の一覧はどこかで取得できるのか？

build.sh では MACHINE_ARCH が設定されてなければ uname を呼び出す。

CVS log for src/build.sh

	# Find information about the build platform.  This should be
	# kept in sync with _HOST_OSNAME, _HOST_OSREL, and _HOST_ARCH
	# variables in share/mk/bsd.sys.mk.
	#
	# Note that "uname -p" is not part of POSIX, but we want uname_p
	# to be set to the host MACHINE_ARCH, if possible.  On systems
	# where "uname -p" fails, prints "unknown", or prints a string
	# that does not look like an identifier, fall back to using the
	# output from "uname -m" instead.
	#
	uname_s=$(uname -s 2>/dev/null)
	uname_r=$(uname -r 2>/dev/null)
	uname_m=$(uname -m 2>/dev/null)
	uname_p=$(uname -p 2>/dev/null || echo "unknown")
	case "${uname_p}" in
	''|unknown|*[^-_A-Za-z0-9]*) uname_p="${uname_m}" ;;
	esac

uname(1) (/usr/bin/uname) は uname(3) (libc) を呼び出している。

CVS log for src/usr.bin/uname/uname.c

	if (uname(&u) != 0) {
		err(EXIT_FAILURE, "uname");
		/* NOTREACHED */
	}

uname(3) (libc) は sysctl を呼び出している

CVS log for src/lib/libc/gen/uname.c

int
uname(struct utsname *name)
{
	int mib[2];
	size_t len;
	char *p;

	_DIAGASSERT(name != NULL);

	mib[0] = CTL_KERN;
	mib[1] = KERN_OSTYPE;
	len = sizeof(name->sysname);
	if (sysctl(mib, 2, &name->sysname, &len, NULL, 0) == -1)
		goto error;

	mib[0] = CTL_KERN;
	mib[1] = KERN_HOSTNAME;
	len = sizeof(name->nodename);
	if (sysctl(mib, 2, &name->nodename, &len, NULL, 0) == -1)
		goto error;

	mib[0] = CTL_KERN;
	mib[1] = KERN_OSRELEASE;
	len = sizeof(name->release);
	if (sysctl(mib, 2, &name->release, &len, NULL, 0) == -1)
		goto error;

	mib[0] = CTL_KERN;
	mib[1] = KERN_VERSION;
	len = sizeof(name->version);
	if (sysctl(mib, 2, &name->version, &len, NULL, 0) == -1)
		goto error;

	/* The version may have newlines in it, turn them into spaces. */
	for (p = name->version; len--; ++p) {
		if (*p == '\n' || *p == '\t') {
			if (len > 1)
				*p = ' ';
			else
				*p = '\0';
		}
	}

	mib[0] = CTL_HW;
	mib[1] = HW_MACHINE;
	len = sizeof(name->machine);
	if (sysctl(mib, 2, &name->machine, &len, NULL, 0) == -1)
		goto error;
	return (0);

error:
	return (-1);
}
