From abe2bb5c40260a31ce5ee27b841bcbd647ff8b88 Mon Sep 17 00:00:00 2001 From: xleroy Date: Sat, 9 Apr 2011 16:59:13 +0000 Subject: Merge of branch "unsigned-offsets": - In pointer values "Vptr b ofs", interpret "ofs" as an unsigned int. (Fixes issue with wrong comparison of pointers across 0x8000_0000) - Revised Stacking pass to not use negative SP offsets. - Add pointer validity checks to Cminor ... Mach to support the use of memory injections in Stacking. - Cleaned up Stacklayout modules. - IA32: improved code generation for Mgetparam. - ARM: improved code generation for op-immediate instructions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1632 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- backend/LTLintyping.v | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'backend/LTLintyping.v') diff --git a/backend/LTLintyping.v b/backend/LTLintyping.v index ad3ad644..c928f3f6 100644 --- a/backend/LTLintyping.v +++ b/backend/LTLintyping.v @@ -89,7 +89,7 @@ Inductive wt_instr : instruction -> Prop := forall arg tbl, Loc.type arg = Tint -> loc_acceptable arg -> - list_length_z tbl * 4 <= Int.max_signed -> + list_length_z tbl * 4 <= Int.max_unsigned -> wt_instr (Ljumptable arg tbl) | wt_Lreturn: forall optres, -- cgit
