From 39b8b2b623087fa643daeed424bd2fa79076f463 Mon Sep 17 00:00:00 2001 From: bjorn3 Date: Sat, 14 Nov 2020 19:16:43 +0100 Subject: Remove StructRet arg attr It is applied exactly when the return value has an indirect pass mode. Except for InReg on x86 fastcall, arg attrs are now only used for optimization purposes and thus are fine to ignore. --- compiler/rustc_target/src/abi/call/mod.rs | 5 ----- 1 file changed, 5 deletions(-) (limited to 'compiler/rustc_target') diff --git a/compiler/rustc_target/src/abi/call/mod.rs b/compiler/rustc_target/src/abi/call/mod.rs index 0931e8a3771..91b004c41d9 100644 --- a/compiler/rustc_target/src/abi/call/mod.rs +++ b/compiler/rustc_target/src/abi/call/mod.rs @@ -59,7 +59,6 @@ mod attr_impl { const NoCapture = 1 << 2; const NonNull = 1 << 3; const ReadOnly = 1 << 4; - const StructRet = 1 << 6; const InReg = 1 << 8; } } @@ -619,10 +618,6 @@ impl<'a, Ty> FnAbi<'a, Ty> { a => return Err(format!("unrecognized arch \"{}\" in target specification", a)), } - if let PassMode::Indirect { ref mut attrs, extra_attrs: _, on_stack: _ } = self.ret.mode { - attrs.set(ArgAttribute::StructRet); - } - Ok(()) } } -- cgit 1.4.1-3-g733a5
