From 8a8ee1a3ed249e4077a7ce0b88903b493419e7d7 Mon Sep 17 00:00:00 2001 From: Tomasz Miąsko Date: Fri, 6 Nov 2020 00:00:00 +0000 Subject: inliner: Use substs_for_mir_body Changes from 68965 extended the kind of instances that are being inlined. For some of those, the `instance_mir` returns a MIR body that is already expressed in terms of the types found in substitution array, and doesn't need further substitution. Use `substs_for_mir_body` to take that into account. --- compiler/rustc_codegen_ssa/src/mir/mod.rs | 14 +++++--------- 1 file changed, 5 insertions(+), 9 deletions(-) (limited to 'compiler/rustc_codegen_ssa/src/mir') diff --git a/compiler/rustc_codegen_ssa/src/mir/mod.rs b/compiler/rustc_codegen_ssa/src/mir/mod.rs index 84e82e88e8e..01fd1681593 100644 --- a/compiler/rustc_codegen_ssa/src/mir/mod.rs +++ b/compiler/rustc_codegen_ssa/src/mir/mod.rs @@ -92,15 +92,11 @@ impl<'a, 'tcx, Bx: BuilderMethods<'a, 'tcx>> FunctionCx<'a, 'tcx, Bx> { T: Copy + TypeFoldable<'tcx>, { debug!("monomorphize: self.instance={:?}", self.instance); - if let Some(substs) = self.instance.substs_for_mir_body() { - self.cx.tcx().subst_and_normalize_erasing_regions( - substs, - ty::ParamEnv::reveal_all(), - &value, - ) - } else { - self.cx.tcx().normalize_erasing_regions(ty::ParamEnv::reveal_all(), *value) - } + self.instance.subst_mir_and_normalize_erasing_regions( + self.cx.tcx(), + ty::ParamEnv::reveal_all(), + value, + ) } } -- cgit 1.4.1-3-g733a5
