In doc/extend.texi we have:
int foo ()
@{
int x = 42;
int *y = &x;
int result;
asm ("magic stuff accessing an 'int' pointed to by '%1'"
"=&d" (r) : "a" (y), "m" (*y));
return result;
@}
two problems, r != result. Second problem, there should be a : before the
output constraint.
The current docs on the web site are unchanged.
