re PR debug/43190 (Used pointer typedefs eliminated from debug info)

Browse Source 
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.
