2337869fbf Pacify gcc 11.1.1 -Wanalyzer-null-argument
* lib-src/etags.c (regexp): Omit member force_explicit_name,

link (tempname, NULL) to be called.

since GCC doesn’t seem to be smart enough to check the single ‘if’.

could be given a NULL arg.

initial value.

* src/emacs.c (real_filename, set_invocation_vars)
(init_vars_for_load): Functions deleted; callers adjusted.

set_invocation_vars.
(load_pdump_find_executable): Make sure the return value has any
symlinks in it expanded.
(load_pdump): Accept only 2 arguments, not 3.  Determine both the
file name of the Emacs executable and of the dump file in
synchronized manner, so that if we decided to look for the dump
file in its hardcoded installation directory, the directory of the
Emacs executable will also be where we expect it to be installed.
Pass only 2 arguments to pdumper_load.  (Bug#47800)  (Bug#44128)
* src/pdumper.c (dump_do_dump_relocation): Use emacs_execdir
instead of Vinvocation_directory to produce absolute file names of
*.eln files that are recorded in the pdumper file.  Pass the full
.eln file name to fixup_eln_load_path.

already did that.  Use explicit const string to avoid "magic"
values.

* lisp/startup.el (normal-top-level): Use expand-file-name instead
of concat.  Decode comp-eln-load-path and expand-file-name its
members.
