re PR debug/45088 (pointer type information lost in debuginfo)
Fix for PR debug/45088
gcc/
* dwarf2out.c (gen_type_die_with_usage): Do not try to emit debug
info for a redundant typedef that has DECL_ORIGINAL_TYPE set. Use
that underlying type instead.
gcc/testsuite/
* g++.dg/debug/dwarf2/self-ref-1.C: New test.
* g++.dg/debug/dwarf2/self-ref-2.C: Likewise.
