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/Constpropproof.v | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'backend/Constpropproof.v') diff --git a/backend/Constpropproof.v b/backend/Constpropproof.v index 16f839fc..714468aa 100644 --- a/backend/Constpropproof.v +++ b/backend/Constpropproof.v @@ -355,6 +355,17 @@ Proof. eapply exec_Itailcall; eauto. apply sig_function_translated; auto. constructor; auto. + (* Ibuiltin *) + TransfInstr. intro. + exists (State s' (transf_function f) sp pc' (rs#res <- v) m'); split. + eapply exec_Ibuiltin; eauto. + eapply external_call_symbols_preserved; eauto. + exact symbols_preserved. exact varinfo_preserved. + econstructor; eauto. + eapply analyze_correct_1; eauto. simpl; auto. + unfold transfer; rewrite H. + apply regs_match_approx_update; auto. simpl; auto. + (* Icond, true *) exists (State s' (transf_function f) sp ifso rs m); split. caseEq (cond_strength_reduction (approx_reg (analyze f)!!pc) cond args); -- cgit
