From 8539759095f95f2fbb680efc7633d868099114c8 Mon Sep 17 00:00:00 2001 From: xleroy Date: Sat, 29 Dec 2012 16:55:38 +0000 Subject: Merge of the clightgen branch: - Alternate semantics for Clight where function parameters are temporaries, not variables - New pass SimplLocals that turns non-addressed local variables into temporaries - Simplified Csharpminor, Cshmgen and Cminorgen accordingly - SimplExpr starts its temporaries above variable names, therefoe Cminorgen no longer needs to encode variable names and temps names. - Simplified Cminor parser & printer, as well as Errors, accordingly. - New tool clightgen to produce Clight AST in Coq-parsable .v files. - Removed side condition "return type is void" on rules skip_seq in the semantics of CompCert C, Clight, C#minor, Cminor. - Adapted RTLgenproof accordingly (now uses a memory extension). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2083 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- backend/CminorSel.v | 1 - 1 file changed, 1 deletion(-) (limited to 'backend/CminorSel.v') diff --git a/backend/CminorSel.v b/backend/CminorSel.v index bb5143c1..a063544d 100644 --- a/backend/CminorSel.v +++ b/backend/CminorSel.v @@ -246,7 +246,6 @@ Inductive step: state -> trace -> state -> Prop := E0 (State f Sskip k sp e m) | step_skip_call: forall f k sp e m m', is_call_cont k -> - f.(fn_sig).(sig_res) = None -> Mem.free m sp 0 f.(fn_stackspace) = Some m' -> step (State f Sskip k (Vptr sp Int.zero) e m) E0 (Returnstate Vundef k m') -- cgit
