From 1e97bb4f6297b6fa7949684e522a592aab754d99 Mon Sep 17 00:00:00 2001 From: Xavier Leroy Date: Thu, 22 Jan 2015 19:26:05 +0100 Subject: Delay reads from !Machine.config before it is properly initialized. Several definitions in Cutil and elsewhere were accessing the default value of !Machine.config, before it is properly initialized in Driver. Delay evaluation of these definitions, and initialize Machine.config to nonsensical values so that lack of initialization is caught early (e.g. in Cutil.find_matching_*_kind). Also, following up on commit [3b8a094], don't use "wchar_t" typedef to type wide string literals, even if this typedef is in scope. The risk here is to hide an inconsistency between "wchar_t"'s definition in standard headers and CompCert's built-in definition. --- cparser/Elab.ml | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'cparser/Elab.ml') diff --git a/cparser/Elab.ml b/cparser/Elab.ml index faffc36f..bad92cf6 100644 --- a/cparser/Elab.ml +++ b/cparser/Elab.ml @@ -1198,7 +1198,7 @@ let elab_expr loc env a = | CONSTANT cst -> let cst' = elab_constant loc cst in - { edesc = EConst cst'; etyp = type_of_constant env cst' } + { edesc = EConst cst'; etyp = type_of_constant cst' } (* 6.5.2 Postfix expressions *) @@ -1339,31 +1339,31 @@ let elab_expr loc env a = match b1.edesc with | EConst(CStr s) -> let sz = String.length s + 1 in - EConst(CInt(Int64.of_int sz, size_t_ikind, "")) + EConst(CInt(Int64.of_int sz, size_t_ikind(), "")) | EConst(CWStr s) -> let sz = (!config).sizeof_wchar * (List.length s + 1) in - EConst(CInt(Int64.of_int sz, size_t_ikind, "")) + EConst(CInt(Int64.of_int sz, size_t_ikind(), "")) | _ -> ESizeof b1.etyp in - { edesc = bdesc; etyp = TInt(size_t_ikind, []) } + { edesc = bdesc; etyp = TInt(size_t_ikind(), []) } | TYPE_SIZEOF (spec, dcl) -> let (ty, env') = elab_type loc env spec dcl in if wrap incomplete_type loc env' ty then err "incomplete type %a" Cprint.typ ty; - { edesc = ESizeof ty; etyp = TInt(size_t_ikind, []) } + { edesc = ESizeof ty; etyp = TInt(size_t_ikind(), []) } | EXPR_ALIGNOF a1 -> let b1 = elab a1 in if wrap incomplete_type loc env b1.etyp then err "incomplete type %a" Cprint.typ b1.etyp; - { edesc = EAlignof b1.etyp; etyp = TInt(size_t_ikind, []) } + { edesc = EAlignof b1.etyp; etyp = TInt(size_t_ikind(), []) } | TYPE_ALIGNOF (spec, dcl) -> let (ty, env') = elab_type loc env spec dcl in if wrap incomplete_type loc env' ty then err "incomplete type %a" Cprint.typ ty; - { edesc = EAlignof ty; etyp = TInt(size_t_ikind, []) } + { edesc = EAlignof ty; etyp = TInt(size_t_ikind(), []) } | UNARY(PLUS, a1) -> let b1 = elab a1 in @@ -1465,7 +1465,7 @@ let elab_expr loc env a = err "illegal pointer arithmetic in binary '-'"; if wrap sizeof loc env ty1 = Some 0 then err "subtraction between two pointers to zero-sized objects"; - (TPtr(ty1, []), TInt(ptrdiff_t_ikind, [])) + (TPtr(ty1, []), TInt(ptrdiff_t_ikind(), [])) | _, _ -> error "type error in binary '-'" end in { edesc = EBinop(Osub, b1, b2, tyop); etyp = tyres } -- cgit
