f35d6a9c73 * CONTRIBUTE: Improve commit message instructions
e0ee1d003a Work around IBM XL C compiler bug
6b99b6eb8b * admin/make-tarball.txt: Various clarifications.
bbf4140091 * admin/diff-tar-files: Don't assume .tar.gz.
0a50ad11db * lisp/tab-bar.el (tab-bar-close-other-tabs): Fix regression.
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/comp.c (maybe_defer_native_compilation): Update to accumulate
delayed objects in `comp--delayed-sources'.
(syms_of_comp): Add `comp--delayed-sources' and `comp--loadable'
vars.
* lisp/startup.el (startup--honor-delayed-native-compilations): New
function.
(normal-top-level): Call it.
* src/comp.c (comp_hash_source_file): Condition code that requires
zlib with HAVE_ZLIB.
* etc/NEWS: Explain that '--without-compress-install' is necessary
when configuring with native compilation but without zlib.
* src/comp.c (DEF_DLL_FN, init_gccjit_functions): Don't load and
don't define functions/macros if libgccjit doesn't have them, to
avoid compiler warnings.
* lisp/emacs-lisp/comp.el ('native-comp-compiler-options): New option.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Add support
for new 'native-comp-compiler-options'.
* src/comp.c (Fcomp_native_compiler_options_effective_p): New function.
(add_compiler_options): New function.
(Fcomp__compile_ctxt_to_file): Call 'add_compiler_options'.
* Makefile.in:
* configure.ac: Change eln file install location to
Contents/Frameworks.
* src/comp.c (hash_native_abi): Replace dots with underscores in the
eln install location as the macOS code-signing tool won't sign the
files if the parent directories have dots.
* src/comp.c (Fcomp_el_to_eln_rel_filename): Don't use
'file-truename', as it is only available once files.el is loaded,
which doesn't work during dumping, until loadup loads files.el.
Instead, use 'realpath'. (Bug#48578)
* src/w32.c (realpath): New function.
* src/w32.h (realpath): Add prototype.
* nt/mingw-cfg.site (ac_cv_func_realpath)
(gl_cv_func_realpath_works): Define to "yes", as this function is
now implemented in w32.c.
* 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.
* src/comp.c (fixup_eln_load_path): Account the fact that the
file can be dumped in the 'preloaded' subfolder.
* lisp/loadup.el: Likewise.
* src/lread.c (maybe_swap_for_eln1): New function.
(maybe_swap_for_eln): Handle 'preloaded' subfolder.
* src/Makefile.in (LISP_PRELOADED): Export preloaded files.
* lisp/emacs-lisp/comp.el (comp-debug): Update docstring and
move default on Windows systems from 0 to 1.
* src/comp.c (Fcomp__compile_ctxt_to_file): Tweak debug
levels.
* src/comp.c (maybe_defer_native_compilation): Check if the file
is registered in 'V_comp_no_native_file_h'.
(syms_of_comp): 'V_comp_no_native_file_h' new global.
* src/lread.c (maybe_swap_for_eln): Register files in
'V_comp_no_native_file_h'.
* lisp/faces.el (tty-run-terminal-initialization): Do not
explicitly load .elc file to not exclude .eln being loaded in
place.
* src/comp.c (Fcomp_el_to_eln_rel_filename): New function.
(Fcomp_el_to_eln_filename): Make use of.
(syms_of_comp): Register 'Scomp_el_to_eln_rel_filename'.
* src/lread.c (maybe_swap_for_eln): Make use of
'Fcomp_el_to_eln_rel_filename' to hash prevent unnecessary
multiple hashing.
* src/comp.c (add_driver_options): Throw an error if
`comp-native-driver-options' is set globally but
'gcc_jit_context_add_driver_option' is not available, ignore for
the file-local case.
