In a patch series I am working on, I'd like to have a non-POD member in dwarf2_per_cu_data. This currently can't be done because dwarf2_per_cu_data is allocated on an obstack and initialized with memset. This patch changes the DWARF reader to allocate objects of this type with 'new'. The various "subclasses" of this type (signatured_type in particular) are now changed to derive from dwarf2_per_cu_data, and also use 'new' for allocation. Regression tested on x86-64 Fedora 32. gdb/ChangeLog 2021-04-30 Tom Tromey <tom@tromey.com> * dwarf2/read.h (struct dwarf2_per_bfd) <allocate_per_cu, allocate_signatured_type>: Change return type. <all_comp_units, all_type_units>: Hold unique pointers.
