From c5bc95676bf2063c54b3f010fc713d95b4e4dd68 Mon Sep 17 00:00:00 2001 From: khyperia Date: Tue, 6 Oct 2020 15:39:12 +0200 Subject: Let backends access span information Sometimes, a backend may need to emit warnings, errors, or otherwise need to know the span of the current item in a basic block. So, add a set_span method to give the backend that information. --- compiler/rustc_codegen_llvm/src/builder.rs | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'compiler/rustc_codegen_llvm/src') diff --git a/compiler/rustc_codegen_llvm/src/builder.rs b/compiler/rustc_codegen_llvm/src/builder.rs index 0c172dc33ba..f496f3283da 100644 --- a/compiler/rustc_codegen_llvm/src/builder.rs +++ b/compiler/rustc_codegen_llvm/src/builder.rs @@ -16,7 +16,7 @@ use rustc_data_structures::small_c_str::SmallCStr; use rustc_hir::def_id::DefId; use rustc_middle::ty::layout::TyAndLayout; use rustc_middle::ty::{self, Ty, TyCtxt}; -use rustc_span::sym; +use rustc_span::{sym, Span}; use rustc_target::abi::{self, Align, Size}; use rustc_target::spec::{HasTargetSpec, Target}; use std::borrow::Cow; @@ -139,6 +139,8 @@ impl BuilderMethods<'a, 'tcx> for Builder<'a, 'll, 'tcx> { unsafe { llvm::LLVMGetInsertBlock(self.llbuilder) } } + fn set_span(&self, _span: Span) {} + fn position_at_end(&mut self, llbb: &'ll BasicBlock) { unsafe { llvm::LLVMPositionBuilderAtEnd(self.llbuilder, llbb); -- cgit 1.4.1-3-g733a5
