[PATCH v3 0/7] Handle foreign type units in .debug_names

[Simon Marchi <simon.marchi@efficios.com>]

This is v3 of:

  https://inbox.sourceware.org/gdb-patches/20260416200256.386186-1-simon.marchi@efficios.com/

I merged the first patch of v2 ("gdb: refuse to produce .gdb_index when
skeletonless type units are present"), ensuring that GDB does not
produce bogus indexes in presence of foreign type units.

I addressed the review comments from v2, which were all pretty minor.
The first patch of this series moves the dwo data structures to a new
dwarf2/dwo.h header file, instead of dwarf2/read.h.  That is the only
one worth re-reviewing, I think, all the others have the Approved-By tag
already.

Simon Marchi (7):
  gdb/dwarf: move dwo_unit and dwo_file to dwo.h
  gdb/dwarf: move dwarf2_cu::section to cu.c
  gdb/dwarf: add dwo_file::find_tus
  gdb/dwarf: generate foreign type units in .debug_names
  gdb/dwarf: add debug output in read-debug-names.c
  gdb/dwarf: add more context to complaints in
    mapped_debug_names_reader::scan_one_entry
  gdb/dwarf: read foreign type units
