From 255cee09b71255051c2b40eae0c88bffce1f6f32 Mon Sep 17 00:00:00 2001 From: xleroy Date: Sat, 20 Apr 2013 07:54:52 +0000 Subject: Big merge of the newregalloc-int64 branch. Lots of changes in two directions: 1- new register allocator (+ live range splitting, spilling&reloading, etc) based on a posteriori validation using the Rideau-Leroy algorithm 2- support for 64-bit integer arithmetic (type "long long"). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2200 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- backend/Constpropproof.v | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'backend/Constpropproof.v') diff --git a/backend/Constpropproof.v b/backend/Constpropproof.v index 580d551..a6385f4 100644 --- a/backend/Constpropproof.v +++ b/backend/Constpropproof.v @@ -186,6 +186,11 @@ Proof. destruct chunk; simpl; auto. congruence. eapply IHil; eauto. omega. + (* Init_int64 *) + destruct H. destruct (zeq pos 0). subst. rewrite Zplus_0_r in H0. + destruct chunk; simpl; auto. + congruence. + eapply IHil; eauto. omega.
