From d226e7aa93425ba2090f423642341a99ab047838 Mon Sep 17 00:00:00 2001 From: Nikita Popov Date: Fri, 19 Sep 2025 14:53:16 +0200 Subject: Use standard attribute logic for allocator shim Use llfn_attrs_from_instance() to generate the attributes for the allocator shim. This ensures that we generate all the usual attributes (and don't get to find out one-by-one that a certain attribute is important for a certain target). Additionally this will enable emitting the allocator-specific attributes (not included here). This change is quite awkward because the allocator shim uses SimpleCx, while llfn_attrs_from_instance uses CodegenCx. I've switched it to use SimpleCx plus tcx/sess arguments where necessary. If there's a simpler way to do this, I'd love to know about it... --- compiler/rustc_codegen_llvm/src/context.rs | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'compiler/rustc_codegen_llvm/src/context.rs') diff --git a/compiler/rustc_codegen_llvm/src/context.rs b/compiler/rustc_codegen_llvm/src/context.rs index 057f525c76f..2478042a2e6 100644 --- a/compiler/rustc_codegen_llvm/src/context.rs +++ b/compiler/rustc_codegen_llvm/src/context.rs @@ -876,7 +876,7 @@ impl<'ll, 'tcx> MiscCodegenMethods<'tcx> for CodegenCx<'ll, 'tcx> { } else { let fty = self.type_variadic_func(&[], self.type_i32()); let llfn = self.declare_cfn(name, llvm::UnnamedAddr::Global, fty); - let target_cpu = attributes::target_cpu_attr(self); + let target_cpu = attributes::target_cpu_attr(self, self.sess()); attributes::apply_to_llfn(llfn, llvm::AttributePlace::Function, &[target_cpu]); llfn } @@ -891,15 +891,15 @@ impl<'ll, 'tcx> MiscCodegenMethods<'tcx> for CodegenCx<'ll, 'tcx> { } fn set_frame_pointer_type(&self, llfn: &'ll Value) { - if let Some(attr) = attributes::frame_pointer_type_attr(self) { + if let Some(attr) = attributes::frame_pointer_type_attr(self, self.sess()) { attributes::apply_to_llfn(llfn, llvm::AttributePlace::Function, &[attr]); } } fn apply_target_cpu_attr(&self, llfn: &'ll Value) { let mut attrs = SmallVec::<[_; 2]>::new(); - attrs.push(attributes::target_cpu_attr(self)); - attrs.extend(attributes::tune_cpu_attr(self)); + attrs.push(attributes::target_cpu_attr(self, self.sess())); + attrs.extend(attributes::tune_cpu_attr(self, self.sess())); attributes::apply_to_llfn(llfn, llvm::AttributePlace::Function, &attrs); } @@ -918,7 +918,7 @@ impl<'ll, 'tcx> MiscCodegenMethods<'tcx> for CodegenCx<'ll, 'tcx> { attributes::apply_to_llfn( llfn, llvm::AttributePlace::Function, - attributes::target_features_attr(self, vec![]).as_slice(), + attributes::target_features_attr(self, self.tcx, vec![]).as_slice(), ); Some(llfn) } else { -- cgit 1.4.1-3-g733a5
