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.
2deb20c Port last_marked change to full-program optimizers
27eb668 Adapt GDB scripts to '--enable-check-lisp-object-type' builds
dac64e3 Avoid optimizing out the last_marked[] array
* etc/emacs-buffer.gdb <$qnil>: New variable.
(ybuffer-list, yset-buffer): Use $qnil for comparing against
'nil', as direct comparison with Qnil doesn't work in a build with
'--enable-check-lisp-object-type'.
* src/.gdbinit: Adapt commands of the temporary breakpoint in
init_sys_modes to a build with '--enable-check-lisp-object-type'.
Prefer straight quotes in random script files, as they are not converted.
Prefer grave quotes in a couple of places in the manual that were missed
earlier, as these quotes are converted.
The DATA_SEG_BITS hack was needed for older 32 bit platforms.
As a result of this change, Emacs won't work on IRIX 6.5 with IRIX
cc, but that platform is so old that SGI itself stopped supporting
it in December 2013. If you still need Emacs on IRIX, please
either compile with GCC and port the undumping code, or run
'./configure --with-wide-int'.
* configure.ac (DATA_SEG_BITS): Remove. All uses removed.
* src/alloc.c (gdb_make_enums_visible): Update to match lisp.h.
* src/lisp.h (GCTYPEBITS): Move definition up, and switch to the
DEFINE_GDB_SYMBOL_START way to define it.
(NONPOINTER_BITS): New macro.
(EMACS_INT): Use it.
[!USE_LSB_TAG && !WIDE_EMACS_INT]: Fail, and suggest reporting
the problem and/or configuring --with-wide-int.
(USE_LSB_TAG): Simplify, based on above changes.
(gdb_DATA_SEG_BITS): Remove. All uses removed.
* src/vm-limit.c (exceeds_lisp_ptr): Remove. All uses removed.
* etc/emacs-buffer.gdb ($tagmask, $valmask): Remove.
(ygetptr): Adjust to recent changes in lisp.h and emacs.c,
by using VALMASK instead of $valmask, CHECK_LISP_OBJECT_TYPE
instead of gdb_use_union, and DATA_SEG_BITS instead of
gdb_data_seg_bits. Also, use $ptr.i rather than $ptr.u.val.
* src/.gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
$bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
(xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
Adjust to changes in lisp.h and emacs.c, by using
CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
instead of gdb_valbits.
(xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
instead of gdb_array_mark_flag.
(xboolvector): Get size from $->size, not $->header.size.
Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
(xreload, hook-run, hookpost-run): Remove.
* src/emacs.c: Include <verify.h>.
(gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
(gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
Remove.
(gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
(gdb_USE_LSB_TAG): New enum constants.
(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
Also define these as enum constants, so they're visible to GDB.
(ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
as constants, so they're visible to GDB.
* src/lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
(PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
Now enum constants, not macros, so they're visible to GDB.
(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
more convenient now. All uses changed.
(VALMASK) [USE_LSB_TAG]: Also define in this case.
* src/mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
