From fffa10c175fcadd8c7f473e1f91d9776cf6c24f6 Mon Sep 17 00:00:00 2001 From: "Felix S. Klock II" Date: Fri, 29 Nov 2013 18:20:27 +0100 Subject: [PATCH] Removed some dead code. While tracking down how this function became dead, identified a spot (@fn cannot happen) where we probably would prefer to ICE rather than pass silently; so added fail! invocation. --- src/librustc/middle/kind.rs | 12 +----------- 1 file changed, 1 insertion(+), 11 deletions(-) diff --git a/src/librustc/middle/kind.rs b/src/librustc/middle/kind.rs index a4348a71d21..bd6e7d528a7 100644 --- a/src/librustc/middle/kind.rs +++ b/src/librustc/middle/kind.rs @@ -182,17 +182,6 @@ fn with_appropriate_checker(cx: &Context, check_freevar_bounds(cx, fv.span, var_t, bounds, None); } - fn check_for_box(cx: &Context, fv: &freevar_entry, bounds: ty::BuiltinBounds) { - // all captured data must be owned - let id = ast_util::def_id_of_def(fv.def).node; - let var_t = ty::node_id_to_type(cx.tcx, id); - - // check that only immutable variables are implicitly copied in - check_imm_free_var(cx, fv.def, fv.span); - - check_freevar_bounds(cx, fv.span, var_t, bounds, None); - } - fn check_for_block(cx: &Context, fv: &freevar_entry, bounds: ty::BuiltinBounds, region: ty::Region) { let id = ast_util::def_id_of_def(fv.def).node; @@ -225,6 +214,7 @@ fn with_appropriate_checker(cx: &Context, .. }) => { // can't happen + fail!("internal error: saw closure with managed sigil (@fn)"); } ty::ty_closure(ty::ClosureTy { sigil: BorrowedSigil,
