memory command on 9pc64

Test if large memory is really allocated to a process.

H2: Test Code

void
main(int argc, char *argv[])
{
	char *p, buf[256];
	ulong i,n[4];
	ulong GB = 1024*1024*1024;

	ARGBEGIN{
	default: usage();
	}ARGEND

	n[0] = 1;
	n[1] = 1;
	n[2] = 1;
	n[3] = 1;

	for(i = 0; i< 4; i++){
		p = malloc(n[i]*GB);
		print("%d %dGB %08p\n",i,n[i],p);
	}
	read(0,buf, sizeof(buf));
}


H2: The Result

H3:	9front (9pc64)

the 6.out is running

Totally OK.
It would be better if we get total memory size allocated to a process.
memory command on both 9pcf and 9pc64 does not show malloced size.
