[Frama-c-discuss] How to get the "VALID" results with dynamically calling wp?

Hi, I have some doubts about wp. A simple program named b.c as below

void phase(void)
  int m;
  int a;
  m = 0;
  a = 10;
  /*@ loop invariant a-10 == 0;
      loop invariant m >= 0;

void main(void)

There are two invariants here. Now run the command "frama-c-gui b.c" and we
can find that both of the status of the invariants is "no verification
If I click the menu "Prove the annotation by WP" on one of them and get the
result is
local status--valid
consolidated status--unkonwn.
Then click the menu on the other invariant and the statuses all become to
be valid.
If wp is dynamically  called with code to prove the invariants it can only
be proved one by one. How to get the "VALID" results above?

Best regards.
