re PR debug/43190 (Used pointer typedefs eliminated from debug info)
PR debug/43190
* function.c (used_types_insert): Don't skip through named pointer
types. Don't use TYPE_MAIN_VARIANT if the original type has a name
and it is different from the main variant's type.
* c-c++-common/dwarf2/pr43190.c: New test.
