From 4297fcb821c3188449b64184af73e41491a6118f Mon Sep 17 00:00:00 2001 From: xleroy Date: Mon, 23 Jul 2012 15:01:54 +0000 Subject: - Revised non-overflow constraints on memory injections so that injections compose (Values, Memdata, Memory) - Memory chunks: Mfloat64 now has alignment 8; introduced Mfloat64al32 that works like old Mfloat64 (i.e. has alignment 4); simplified handling of memcpy builtin accordingly. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1983 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- common/Events.v | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'common/Events.v') diff --git a/common/Events.v b/common/Events.v index 93e18278..b36a86f1 100644 --- a/common/Events.v +++ b/common/Events.v @@ -1283,7 +1283,7 @@ Qed.
