      Bring back dmpstruct.h · 9994bf17
      Paul Eggert authored
      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

      Remove the need for temacs.in · d8260374
      Paul Eggert authored
      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.

      Remove assumption of uint64_t etc. in portable code · e44ff2de
      Paul Eggert authored
      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.

      Remove dmpstruct.h · 44a39e3e
      Paul Eggert authored
      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.

      Modularize bignums better · 9abaf5f3
      Paul Eggert authored
      * 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.

      Prefer HTTPS to FTP and HTTP in documentation · bc511a64
      Paul Eggert authored
      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.
