* src/comp.h, src/thread.h: Add INLINE_HEADER_BEGIN and
INLINE_HEADER_END, since it uses INLINE.
* src/emacs.c: Include these two files.

The C standard does not allow size-zero arrays, so redo struct
Lisp_Subr to not use size-zero arrays when native compilation is
not being used. Formerly, the code was using size-zero arrays (a
GNU C extension) to avoid using memory unnecessarily when
HAVE_NATIVE_COMP is not defined. Replace this hack with the
more-traditional hack of putting the relevant members inside
‘#ifdef HAVE_NATIVE_COMP’.
* src/alloc.c (cleanup_vector, mark_object):
* src/comp.c (make_subr):
* src/data.c (Fsubr_native_lambda_list, Fsubr_native_comp_unit):
* src/eval.c (init_eval_once, funcall_lambda):
* src/lisp.h (SUBR_NATIVE_COMPILEDP, SUBR_NATIVE_COMPILED_DYNP)
(SUBR_TYPE):
* src/lread.c (Fload):
Conditionally compile with ‘#ifdef HAVE_NATIVE_COMP’ instead of
with ‘if (NATIVE_COMP_FLAG)’. Redo members like native_comp_u[0]
to be plain native_comp_u. Put all uses of these members inside
‘#ifdef HAVE_NATIVE_COMP’.
* src/lisp.h (struct Lisp_Subr): Members native_comp_u,
native_c_name, lambda_list, type are now all ifdeffed out if
HAVE_NATIVE_COMP is not defined, instead of being size-zero
arrays. All uses changed.
* src/pdumper.c (dump_subr, dump_cold_native_subr)
(dump_do_dump_relocation):
* src/comp.h (NATIVE_COMP_FLAG): Remove; no longer needed.

* src/emacs.c (real_filename, set_invocation_vars)
(init_vars_for_load): Functions deleted; callers adjusted.
(init_cmdargs): Put back all the code which was extracted into
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.
(pdumper_set_emacs_execdir) [HAVE_NATIVE_COMP]: New function.
(pdumper_load) [HAVE_NATIVE_COMP]: Call pdumper_set_emacs_execdir.
* src/comp.c (fixup_eln_load_path): Use Fsubstring_no_properties
instead of Fsubstring. No need to cons a file name, as the caller
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.

* lisp/emacs-lisp/comp.el (comp-emit-for-top-level): Synthesize
'top_level_run' so it returns the last value returned by
`comp--register-subr'.
* src/comp.c (load_comp_unit): Return what 'top_level_run'
returns.
(Fnative_elisp_load): Return what 'load_comp_unit' returns.

When recompiling remove the corresponding stale elns found in the
`comp-eln-load-path'.
When removing a package remove the corresponding elns too.
On Windows both of these are performed only when possible, when it's
not the file is renamed as .eln.old and a last attempt to remove this
is performed closing the Emacs session. When a file being deleted was
loaded by multiple Emacs sessions the last one being closed should
delete it.
* lisp/emacs-lisp/comp.el (comp-clean-up-stale-eln): New function.
(comp-delete-or-replace-file): Rename from
`comp--replace-output-file' and update so it can be used for
replacing or deleting shared libs safetly.
* lisp/emacs-lisp/package.el (package--delete-directory): When
native compiled just call `comp-clean-up-stale-eln' for each
eln file we want to clean-up.
* src/alloc.c (cleanup_vector): Call directly the dynlib_close.
* src/comp.c (syms_of_comp): Update for comp_u->cfile removal.

be the filename.

is fully completed.

all_loaded_comp_units_h the load filename.

rename.

Removing `Vcomp_sym_subr_c_name_h' all c_name functions are GC
markable only through 'data_ephemeral_vec'. A recursive load must not
overide its content otherwise a previously activated load will have
the original content collected before it's used.

field.
* src/comp.c (unset_cu_load_ongoing): New function.

When closing emacs will inspect all directories from which it loaded
native compilation units. If it finds a ".eln.old" file it will try to
delete it, if it fails that means that another Emacs instance is using it.
When compiling a file we rename the file that was in the output path
in case it has been loaded into another Emacs instance.
When deleting a package we move any ".eln" or ".eln.old" files in the
package folder that we can't delete to `package-user-dir`. Emacs will
check that directory when closing and delete them.
* lisp/emacs-lisp/comp.el (comp--replace-output-file): Function called
from C code to finish the compilation process. It performs renaming of
the old file if necessary.
* lisp/emacs-lisp/package.el (package--delete-directory): Function to
delete a package directory. It moves native compilation units that it
can't delete to `package-user-dir'.
* src/alloc.c (cleanup_vector): Call dispose_comp_unit().
(garbage_collect): Call finish_delayed_disposal_of_comp_units().
* src/comp.c: Restore the signal mask using unwind-protect. Store
loaded native compilation units in a hash table for disposal on
close. Store filenames of native compilation units GC'd in a linked
list to finish their disposal when the GC is over.
(clean_comp_unit_directory): Delete all *.eln.old files in a
directory.
(clean_package_user_dir_of_old_comp_units): Delete all *.eln.old files
in `package-user-dir'.
(dispose_all_remaining_comp_units): Dispose of native compilation
units that are still loaded.
(dispose_comp_unit): Close handle and cleanup directory or arrange for
later cleanup if DELAY is true.
(finish_delayed_disposal_of_comp_units): Dispose of native compilation
units that were GC'd.
(register_native_comp_unit): Register native compilation unit for
disposal when Emacs closes.
* src/comp.h: Introduce cfile member in Lisp_Native_Comp_Unit.
Add declarations of functions that: clean directories of unused native
compilation units, handle disposal of native compilation units.
* src/emacs.c (kill-emacs): Dispose all remaining compilation units
right right before calling exit().
* src/eval.c (internal_condition_case_3, internal_condition_case_4):
Add functions.
* src/lisp.h (internal_condition_case_3, internal_condition_case_4):
Add functions.
* src/pdumper.c (dump_do_dump_relocation): Set cfile to a copy of the
Lisp string specifying the file path.
