Now that -Og inlining has been improved this is no longer helpful.
* src/Makefile.in (KEY_OPS_CFLAGS): Remove. All uses removed.
This improved CPU performance of ‘make compile-always’ by 5% on my
platform, which was gcc -Og, GCC 9.3.1 20200317 (Red Hat 9.3.1-1),
Fedora 31 x86-64 (AMD Phenom II X4 910e, circa 2010).

Bring back the dmpstruct.h checking, and use it when
--enable-checking=structs is specified. The checking can be helpful
to some developers, although it gets in the way of others and is

implied by --enable-checking.

Problem reported by Andy Moreton in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00359.html
* src/Makefile.in (${charsets}, $(lispsource)/loaddefs.el):
Revert incorrect changes to $(MAKE) -C invocations when the
target is in the source tree not the build tree.
|

Instead of building a file temacs.in used only to compute a
fingerprint, compute the fingerprint directly from the .o and
.a files that go into temacs.in. This speeds up the build by
avoiding the need to link temacs twice, once with a dummy
fingerprint.
* lib-src/make-fingerprint.c (main): No need to generate
a fingerprint file that includes config.h, now that fingerprint.c
depends on all the .o files.
* src/Makefile.in ($(libsrc)/make-fingerprint$(EXEEXT)):
Use the same rule as $(libsrc)/make-docfile$(EXEEXT).
* src/fingerprint-dummy.c: Remove.
* src/Makefile.in (${charsets}, $(libsrc)/make-docfile$(EXEEXT))
($(LIBEGNU_ARCHIVE), $(lwlibdir)/liblw.a, $(oldXMenudir)/libXMenu11.a)
(../config.status, ${ETAGS}, ../lisp/TAGS, $(lwlibdir)/TAGS)
($(lispsource)/loaddefs.el):
Prefer ‘$(MAKE) -C $(dir $@)’ to ‘${MAKE} -C SOMESTRING’ when
either will do, as the former is more regular and lets us
coalesce rules better.
(EMACS_DEPS_PRE, EMACS_DEPS_POST, BUILD_EMACS_PRE)
(BUILD_EMACS_POST, temacs.in$(EXEEXT)): Remove.
(FINGERPRINTED): New macro.
(fingerprint.c): Use it instead of temacs.in$(EXEEXT), to
avoid the need to build temacs.in at all.
(temacs$(EXEEXT)): No need to depend on other .o files now;
fingerprint.o is enough, since it depends on the rest.
Spell out what used to be in BUILD_EMACS_PRE and BUILD_EMACS_POST.
(mostlyclean): No need to remove temacs.in.

C11 doesn’t guarantee the existence of types like uint64_t,
so avoid these types in portable code, as it’s easy to do so.
There’s no need to avoid the types in w32-specific code,
since w32 is guaranteed to have them.
* lib-src/make-fingerprint.c (main):
* src/fingerprint-dummy.c:
* src/fingerprint.h:
* src/pdumper.c (dump_fingerprint, struct dump_header):
Prefer unsigned char to uint8_t in portable code, as either will do.
Put an "#include <config.h>" in fingerprint.c files, so
that the corresponding .o file is rebuilt after ./configure is run.
* lib-src/make-fingerprint.c (main):
Simplify loop.
* src/Makefile.in (fingerprint.c): Update atomically.
* src/pdumper.c: Omit unnecessary check that off_t is the same
size as int32_t or int64_t, as the code does not rely on this
assumption.
(dump_off): Use int_least32_t, not int32_t.
(struct dump_reloc): Use unsigned int, not uint32_t.
(dump_anonymous_allocate_w32, dump_anonymous_allocate_posix)
(dump_anonymous_allocate, dump_map_file_w32, dump_map_file_posix)
(dump_map_file:
Do the sanity checks at compile time, not at run-time, to avoid
usage of uint64_t etc. on non-w32 platforms.

The hassles of updating the dmpstruct.h-using code bit me again.
These updates are more trouble than they’re worth. See:
https://lists.gnu.org/r/emacs-devel/2019-03/msg00122.html
As I’m the main person who’s made changes in this area since
dmpstruct.h was introduced, I’m the most motivated to clean up
the situation.
* make-dist (possibly_non_vc_files): Remove src/dmpstruct.h.
* src/Makefile.in (dmpstruct_headers, dmpstruct.h): Remove.
(pdumper.o): Do not depend on dmpstruct.h.
(mostlyclean): Do not remove dmpstruct.h.
* src/dmpstruct.awk: Remove.
* src/pdumper.c: Do not include dmpstruct.h.
(CHECK_STRUCTS): Remove. All uses removed.

This does not change behavior; it’s just long-overdue
refactoring (Bug#32902).
* src/emacs.c (main): Call init_timefns, syms_of_timefns.
* src/timefns.c: New file, containing timestamp-related stuff
from editfns.c and sysdep.c.
* src/Makefile.in (base_obj): Add timefns.o.
* src/editfns.c: Simplify by moving a big chunk to timefns.c.
Do not include systime.h, sys/resource.h, sys/param.h,
strftime.h, coding.h.

(time_add, time_subtract, time_arith, Ftime_add)
(Ftime_subtract, Ftime_less_p, Fget_internal_run_time)

(emacs_getenv_TZ, emacs_setenv_TZ): Move to timefns.c.
* src/emacs.c (main): Adjust to initialization changes.
* src/sysdep.c: Include <sys/resource.h> if it's present.
Regularize includes a bit.
(Fget_internal_run_time): Move here from editfns.c.
(init_timefns, syms_of_timefns): New functions.
* src/w32.h (w32_get_internal_run_time): Move decl here
so that it need not be cloned.
* test/src/editfns-tests.el:
* test/src/editfns-tests.el (format-time-string-with-zone)
(format-time-string-with-outlandish-zone)

Problem reported by T.V Raman in:

Say ‘rm ./*.o’ instead of ‘rm *.o’ to avoid undesirable failure
when a file name begins with ‘-’.

* src/bignum.c, src/bignum.h: New files. Only modules that
need to know how bignums are implemented should include
bignum.h. Currently these are alloc.c, bignum.c (of course),
data.c, emacs.c, emacs-module.c, floatfns.c, fns.c, print.c.
* src/Makefile.in (base_obj): Add bignum.o.
* src/alloc.c (make_bignum_str): Move to bignum.c.
(make_number): Remove; replaced by bignum.c’s make_integer.
All callers changed.
* src/conf_post.h (ARG_NONNULL): New macro.
* src/json.c (json_to_lisp): Use it.
* src/data.c (Fnatnump):
Move NATNUMP’s implementation here from lisp.h.
* src/data.c (Fnumber_to_string):
* src/editfns.c (styled_format):
Move conversion of string to bignum to bignum_to_string, and
call it here.
* src/emacs-module.c (module_make_integer):
* src/floatfns.c (Fabs):
Simplify by using make_int.
* src/emacs.c: Include bignum.h, to expand its inline fns.
* src/floatfns.c (Ffloat): Simplify by using XFLOATINT.
(rounding_driver): Simplify by using double_to_bignum.
(rounddiv_q): Clarify use of temporaries.
* src/lisp.h: Move decls that need to know bignum internals to
bignum.h. Do not include gmp.h or mini-gmp.h; that is now
bignum.h’s job.
(GMP_NUM_BITS, struct Lisp_Bignum, XBIGNUM, mpz_set_intmax):
Move to bignum.h.
(make_int): New function.
(NATNUMP): Remove; all callers changed to use Fnatnump.
(XFLOATINT): If arg is a bignum, use bignum_to_double, so that
bignum internals are not exposed here.
* src/print.c (print_vectorlike): Use SAFE_ALLOCA to avoid the
need for a record_unwind_protect_ptr.

This is in preparation for using Gnulib regex for etags,
to avoid collisions in include directives.

* src/Makefile.in: Note that TAGS are generated in build dir.

The check-syntax target is enabled the use of Flymake's "legacy"
backend, flymake-proc-legacy-flymake in src/*.c. It works quite well
with C sources. The green light for this change had already been
given some time ago in
https://lists.gnu.org/archive/html/emacs-devel/2017-10/msg00385.html
* src/Makefile.in (check-syntax): New target.
(.PHONY): Add check-syntax.
|
|
* src/Makefile.in (all): Move target ahead of dep-file inclusion.
|
|
* configure.ac: Use EMACS_CHECK_MODULES fors LCMS2 rather than
AC_SEARCH_LIBS.
* src/Makefile.in: Get LCMS2_LIBS and LCMS2_CFLAGS from configure,
instead of just LIBLCMS2.

It already exists in the Cygwin-w32 build.
* src/w32fns.c (Fw32_battery_status): Move to...

the MS Windows and Cygwin builds.
(syms_of_w32cygwinx): New function.
* src/lisp.h: Add prototype of syms_of_w32cygwinx.
* src/emacs.c (main) [HAVE_NTGUI or CYGWIN]: Call syms_of_w32cygwinx.
* src/Makefile.in (SOME_MACHINE_OBJECTS):
* configure.ac (W32_OBJ) [HAVE_W32]: Add w32cygwinx.o.
(W32_LIBS) [CYGWIN]: Set equal to "-lkernel32" in non-w32 build.
(W32_OBJ) [CYGWIN]: Set equal to "w32cygwinx.o" in non-w32 build.
* etc/NEWS: Document the new battery support.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
