From a82c9c0e4a0b8e37c9c3ea5ae99714982563606f Mon Sep 17 00:00:00 2001 From: xleroy Date: Sat, 14 Jan 2012 14:23:26 +0000 Subject: Merge of the nonstrict-ops branch: - Most RTL operators now evaluate to Some Vundef instead of None when undefined behavior occurs. - More aggressive instruction selection. - "Bertotization" of pattern-matchings now implemented by a proper preprocessor. - Cast optimization moved to cfrontend/Cminorgen; removed backend/CastOptim. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1790 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- backend/Linearizeproof.v | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'backend/Linearizeproof.v') diff --git a/backend/Linearizeproof.v b/backend/Linearizeproof.v index 2f96a09b..50db0c65 100644 --- a/backend/Linearizeproof.v +++ b/backend/Linearizeproof.v @@ -629,12 +629,14 @@ Proof. traceEq. econstructor; eauto. - (* Lcond true *) + (* Lcond *) destruct (find_label_lin_inv _ _ _ _ _ TRF H REACH AT) as [c' EQ]. simpl in EQ. subst c. + destruct b. + (* true *) assert (REACH': (reachable f)!!ifso = true). eapply reachable_successors; eauto. simpl; auto. - exploit find_label_lin_succ; eauto. inv WTI; auto. intros [c'' AT']. + exploit find_label_lin_succ; eauto. inv WTI; eauto. intros [c'' AT']. destruct (starts_with ifso c'). econstructor; split. eapply plus_left'. @@ -648,10 +650,7 @@ Proof. econstructor; split. apply plus_one. eapply exec_Lcond_true; eauto. econstructor; eauto. - - (* Lcond false *) - destruct (find_label_lin_inv _ _ _ _ _ TRF H REACH AT) as [c' EQ]. - simpl in EQ. subst c. + (* false *) assert (REACH': (reachable f)!!ifnot = true). eapply reachable_successors; eauto. simpl; auto. exploit find_label_lin_succ; eauto. inv WTI; auto. intros [c'' AT']. -- cgit
