Hi,

The command `frama-c-gui henry1.c -wp` will prove all of your invariants
at once.

Another solution is to call Frama-C programatically, ie:

    frama-c henry1.c -wp -then -report

Then WP yields:
    [wp] [WP:simplified] Goal store_phase_loop_inv_established : Valid
    [wp] [WP:simplified] Goal store_phase_loop_inv_2_established : Valid
    [wp] [Alt-Ergo] Goal store_phase_loop_inv_preserved : Valid
    [wp] [Alt-Ergo] Goal store_phase_loop_inv_2_preserved : Valid

and Report synthesizes:
--------------------------------------------------------------------------------
--- Properties of Function 'phase'
--------------------------------------------------------------------------------

[  Valid  ] Invariant (file henry1.c, line 7)
            by WP-Store.
[  Valid  ] Invariant (file henry1.c, line 8)
            by WP-Store.

--------------------------------------------------------------------------------
--- Status Report Summary
--------------------------------------------------------------------------------
     2 Completely validated
     2 Total

HTH,
Florent.
