[PATCH v3 0/7] Fix printing macros

[Simon Marchi <simon.marchi@polymtl.ca>]

Hi,

This is v3 of

  https://sourceware.org/pipermail/gdb-patches/2022-April/188230.html

This new attempt uses an approach similar to v2 (use complete paths to
identify symtabs/subfiles and macro_source_files).  But instead
modifying the existing filename/name fields of symtab and subfile, and
therefore causing important UI changes, this new version adds the
information in a new field.

Patches 3 and 4 are preparatory.  Patch 6 removes some code that I
believe is made obsolete by patch 5.

Simon Marchi (7):
  gdb: introduce symtab_create_debug_printf
  gdb: add debug prints in buildsym.c
  gdb/dwarf: pass compilation directory to line header
  gdb/dwarf: pass a file_entry to line_header::file_file_name
  gdb: add "id" fields to identify symtabs and subfiles
  gdb: remove code to prepend comp dir in
    buildsym_compunit::start_subfile
  gdb/testsuite: add macros test for source files compiled in various
    ways
