test/Shell/SymbolFile/DWARF/DW_TAG_basic_type_DW_ATE_UTF_nonC.ll

;
; This test verifies that DWARF DIE of type DW_TAG_basic_type with DW_ATE_UTF
; are matched based on their bit size (8, 16, 32) in addition to their name.
;
; This is used by languages which don't use the C(++) naming of
; `char{8,16,32}_t`, e.g. the D programming language uses `char`, `wchar`, `dchar`.
;
; The D code used to generate this IR is:
; ```
; // Compiled with `ldc2 --mtriple=x86_64-pc-linux -betterC -g -c --output-ll utftypes.d`
; __gshared string utf8 = "Hello";
; __gshared wstring utf16 = "Dlang"w;
; __gshared dstring utf32 = "World"d;
; ```
;
; Note: lldb will print types differently before and after 'run'.
