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/Lineartyping.v | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'backend/Lineartyping.v') diff --git a/backend/Lineartyping.v b/backend/Lineartyping.v index 028e120..4ea2ea9 100644 --- a/backend/Lineartyping.v +++ b/backend/Lineartyping.v @@ -87,6 +87,12 @@ Inductive wt_instr : instruction -> Prop := tailcall_possible sig -> match ros with inl r => r = IT1 | _ => True end -> wt_instr (Ltailcall sig ros) + | wt_Lbuiltin: + forall ef args res, + List.map mreg_type args = (ef_sig ef).(sig_args) -> + mreg_type res = proj_sig_res (ef_sig ef) -> + arity_ok (ef_sig ef).(sig_args) = true -> + wt_instr (Lbuiltin ef args res) | wt_Llabel: forall lbl, wt_instr (Llabel lbl) -- cgit v1.2.3
