## Test that dsymutil correctly handles -gsimple-template-names, where
## DW_AT_name does not include template parameters and template arguments are
## represented as DW_TAG_template_type_parameter children instead.
##
## CU1 defines MyTemplate<int> and MyTemplate<float> (both named "MyTemplate").
## CU2 defines MyTemplate<float> (also named "MyTemplate").
##
## dsymutil must not incorrectly unify MyTemplate<int> with MyTemplate<float>.
## CU2's MyTemplate<float> should unify with CU1's MyTemplate<float>.
## Classic linker: CU1 keeps both specializations. CU2's type reference is
## redirected to CU1's MyTemplate<float>.
##
## Type references use 0x00000000[[VAR]] to match DWARF32 ref_addr (8 hex digit
## DIE offset zero-extended to 16 hex digits for the 8-byte ref_addr).
