dlltool copies strings with strdup all over the place, seeming to take
the attitude that anything might be modified. That leads to lots of
memory leaks. Fixing the leaks by removing the strdup calls of course
means you need to take good care that strings *aren't* modified. This
isn't as easy as it sounds due to functions like xlate that have
const char* params but then manage to modify the strings. I've fixed
xlate, but if I've missed something somewhere then this patch likely
will break dlltool. Testsuite coverage of dlltool isn't good.
The leaks in defparse.y are small. It also is a little work to verify
that all the strings I'm freeing in defparse.y are in fact malloc'd,
which is no doubt why the leaks are there.
Using bfd_xalloc in make_one_lib_file and functions called from there
results in memory being freed automatically at the bfd_close in
make_one_lib_file, without any fuss.
The patch also makes use of xasprintf to replace xmalloc followed by
sprintf.
* defparse.y (opt_name2): Free incoming ID strings after
adding prefix/suffix.
* dlltool.c (struct ifunct): Constify char* fields.
(struct iheadt, struct dlist): Likewise.
(set_dll_name_from_def, def_heapsize, def_stacksize),
(def_section, assemble_file): Use xasprintf.
(def_name, def_library): Free dll_name and name.
(def_description, new_directove): Don't strdup incoming args.
(append_import): Likewise.
(def_import): Free module after appending dllext.
(run): Free temp_base.
(scan_filtered_symbols): Don't segfault on NULL strchr return.
Remove unnecessary strdup.
(scan_drectve_symbols): Likewise. Constify pointers.
Use bfd_malloc_and_get_section. Use xmemdup.
(add_excludes): Use xasprintf and xstrdup.
(gen_exp_file): Free xlate return. Constify pointer to suit
struct changes. Free copy.
(xlate): Always copy arg. Use xasprintf and xstrdup.
(make_imp_label): Add bfd arg. Use bfd_xalloc.
(gen_lib_file): Adjust to suit.
(make_one_lib_file): Likewise. Use bfd_xalloc for section data
and relocs. Simplify code calling xlate, and free xlate return.
(dll_name_list_free_contents): Flatten recursion.
(mangle_defs): Free d_export_vec.
(main): Formatting. Use xasprintf.
* resres.c (write_res_id): Free section data.
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
