From 9c7c84cc40eaacc1e2c13091165785cddecba5ad Mon Sep 17 00:00:00 2001 From: xleroy Date: Tue, 29 Jun 2010 08:27:14 +0000 Subject: Support for inlined built-ins. AST: add ef_inline flag to external functions. Selection: recognize calls to inlined built-ins and inline them as Sbuiltin. CminorSel to Asm: added Sbuiltin/Ibuiltin instruction. PrintAsm: adapted expansion of builtins. C2Clight: adapted detection of builtins. Conventions: refactored in a machine-independent part (backend/Conventions) and a machine-dependent part (ARCH/SYS/Conventions1). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1356 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- backend/RTLgenproof.v | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'backend/RTLgenproof.v') diff --git a/backend/RTLgenproof.v b/backend/RTLgenproof.v index a96dfbfd..a1bd6618 100644 --- a/backend/RTLgenproof.v +++ b/backend/RTLgenproof.v @@ -1213,6 +1213,22 @@ Proof. rewrite H2; eauto. traceEq. rewrite G. constructor; auto. + + (* builtin *) + inv TS. + exploit transl_exprlist_correct; eauto. + intros [rs' [E [F [G J]]]]. + exploit tr_store_optvar_correct. eauto. eauto. + apply match_env_update_temp. eexact F. eauto. + intros [rs'' [A B]]. + econstructor; split. + left. eapply star_plus_trans. eexact E. eapply plus_left. + eapply exec_Ibuiltin. eauto. rewrite G. + eapply external_call_symbols_preserved; eauto. + exact symbols_preserved. exact varinfo_preserved. + eexact A. reflexivity. traceEq. + econstructor; eauto. constructor. rewrite Regmap.gss in B. auto. + (* seq *) inv TS. econstructor; split. -- cgit
