From be454f056fc7637da6d1922c532d73831dc072db Mon Sep 17 00:00:00 2001 From: Arlo Siemsen Date: Thu, 14 Oct 2021 10:26:42 -0700 Subject: Change `char` type in debuginfo to DW_ATE_UTF Rust previously encoded the `char` type as DW_ATE_unsigned_char. The more appropriate encoding is DW_ATE_UTF. Clang uses this same debug encoding for char32_t. This fixes the display of `char` types in Windows debuggers as well as LLDB. --- compiler/rustc_codegen_llvm/src/debuginfo/metadata.rs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'compiler/rustc_codegen_llvm/src') diff --git a/compiler/rustc_codegen_llvm/src/debuginfo/metadata.rs b/compiler/rustc_codegen_llvm/src/debuginfo/metadata.rs index ef87b7b1a7e..4ca92b3efe0 100644 --- a/compiler/rustc_codegen_llvm/src/debuginfo/metadata.rs +++ b/compiler/rustc_codegen_llvm/src/debuginfo/metadata.rs @@ -87,7 +87,7 @@ const DW_ATE_signed: c_uint = 0x05; #[allow(non_upper_case_globals)] const DW_ATE_unsigned: c_uint = 0x07; #[allow(non_upper_case_globals)] -const DW_ATE_unsigned_char: c_uint = 0x08; +const DW_ATE_UTF: c_uint = 0x10; pub const UNKNOWN_LINE_NUMBER: c_uint = 0; pub const UNKNOWN_COLUMN_NUMBER: c_uint = 0; @@ -933,7 +933,7 @@ fn basic_type_metadata<'ll, 'tcx>(cx: &CodegenCx<'ll, 'tcx>, t: Ty<'tcx>) -> &'l ty::Never => ("!", DW_ATE_unsigned), ty::Tuple(elements) if elements.is_empty() => ("()", DW_ATE_unsigned), ty::Bool => ("bool", DW_ATE_boolean), - ty::Char => ("char", DW_ATE_unsigned_char), + ty::Char => ("char", DW_ATE_UTF), ty::Int(int_ty) if cpp_like_debuginfo => (int_ty.msvc_basic_name(), DW_ATE_signed), ty::Uint(uint_ty) if cpp_like_debuginfo => (uint_ty.msvc_basic_name(), DW_ATE_unsigned), ty::Float(float_ty) if cpp_like_debuginfo => (float_ty.msvc_basic_name(), DW_ATE_float), -- cgit 1.4.1-3-g733a5
