re PR c++/44188 (Fails to produce DW_AT_typedef for typedef of anonymous struct)
Fix PR c++/44188
gcc/ChangeLog:
PR c++/44188
* c-common.c (is_typedef_decl): Move this definition ...
* tree.c (is_typedef_decl): ... here.
(typdef_variant_p): Move definition here from gcc/cp/tree.c.
* c-common.h (is_typedef_decl): Move this declaration ...
* tree.h (is_typedef_decl): ... here.
(typedef_variant_p): Move declaration here from gcc/cp/cp-tree.h
* dwarf2out.c (is_naming_typedef_decl): New function.
(gen_tagged_type_die): Split out of ...
(gen_type_die_with_usage): ... this function. When an anonymous
tagged type is named by a typedef, make sure a DW_TAG_typedef DIE
is emitted for the typedef.
(gen_typedef_die): Emit DW_TAG_typedef also for typedefs naming
anonymous tagged types.
gcc/cp/ChangeLog:
PR c++/44188
* cp-tree.h (typedef_variant_p): Move this declaration to
gcc/tree.h.
* tree.c (typedef_variant_p): Move this definition to gcc/tree.c.
* decl.c (grokdeclarator): Do not rename debug info of an
anonymous tagged type named by a typedef.
gcc/testsuite/ChangeLog:
PR c++/44188
* g++.dg/debug/dwarf2/typedef3.C: New test.
