Do not try to redefine the 'abort' function. Instead, redo
the code so that it calls 'emacs_abort' rather than 'abort'.
This removes the need for the NO_ABORT configure-time macro
and makes it easier to change the abort code to do a backtrace.
* configure.ac (NO_ABRT): Remove.
* admin/CPP-DEFINES (NO_ABORT): Remove.
* nt/inc/ms-w32.h (w32_abort) [HAVE_NTGUI]: Remove.
* src/.gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
* src/emacs.c (abort) [!DOS_NT && !NO_ABORT]:
Remove; sysdep.c's emacs_abort now takes its place.
* src/lisp.h (emacs_abort): New decl. All calls from Emacs code to
'abort' changed to use 'emacs_abort'.
* src/msdos.c (dos_abort) [defined abort]: Remove; not used.
(abort) [!defined abort]: Rename to ...
(emacs_abort): ... new name.
* src/sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
the place of the old 'abort' in emacs.c.
* src/w32.c, src/w32fns.c (abort): Do not #undef.
* src/w32.c (emacs_abort): Rename from w32_abort.

src/.gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
and later about non-assignments with no effect. See discussion at
http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
details.

* src/lisp.h (struct Lisp_Symbol): Change xname to meaningful
name since all xname users are fixed long time ago. Do not use
INTERNAL_FIELD.
(set_symbol_name, set_symbol_function, set_symbol_plist):
(set_symbol_next, set_overlay_plist): New function.
(struct Lisp_Cons): Do not use INTERNAL_FIELD.

src/.gdbinit (xcar, xcdr, xlist, xwindow, nextcons, xprintsym):
Adapt to latest changes in field names of the corresponding Lisp
objects.
|
|
|
|
|
| |
src/.gdbinit (xframe): Adapt to introduction of FVAR and the
resulting renaming of 'struct frame' members.

* .gdbinit (xvectype, xpr, xbacktrace): Adjust to reflect the
2012-07-04 changes to pseudovector representation. Problem
reported by Eli Zaretskii in <http://bugs.gnu.org/1995-05-30T23:07:[email protected]#30>.

* .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
arms of an 'if', not using conditional expressions; otherwise GDB
complains about the types in the unevaluated arm when the argument
is an integer literal.
(xgetint): Simplify expression.
* alloc.c (gdb_make_enums_visible): New constant. This ports to
GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
Zaretskii in <http://bugs.gnu.org/1995-05-30T23:07:[email protected]#13>.
* lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
needed now that we have gdb_make_enums_visible.
(enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
(enum enum_USE_LSB_TAG):
New enum types, packaging up enums that need to be exported to GDB.

* 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.

|

* lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
than macros. This simplifies debugging in the usual case, since
it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
and it allows expressions involving EMACS_INT casts.
* .gdbinit (xreload): Simplify by using EMACS_INT cast.

src/w32term.c (x_draw_glyphless_glyph_string_foreground): Draw the
box before drawing the glyphs inside it.
src/dispextern.h (enum glyphless_display_method): Rename
GLYPHLESS_DISPLAY_HEXA_CODE to GLYPHLESS_DISPLAY_HEX_CODE. All
users changed.
src/term.c (append_glyphless_glyph, produce_glyphless_glyph): Fix
comments.
(produce_glyphless_glyph): Enclose "U+nnnn" and "empty box"
whitespace in "[]", to simulate a box. Don't use uninitialized
variable `width'.
lisp/international/characters.el (glyphless-char-display-control):
Renamed from glyphless-char-control; all users changed. Doc fix.
Signal an error if display method is not one of the recognized
symbols.
doc/emacs/rmail.texi (Rmail Coding): Characters with no fonts are not
necessarily displayed as empty boxes.
doc/emacs/mule.texi (Language Environments, Fontsets): Characters with no
fonts are not necessarily displayed as empty boxes.
doc/emacs/display.texi (Text Display): Document display of glyphless

.gdbinit (prowlims): Display row->minpos and row->maxpos.
Display truncated_on_left_p and truncated_on_right_p flags.
Formatting fixes.
(pmtxrows): Display the ordinal number of each row. Don't display
rows beyond the last one.
xdisp.c (RECORD_MAX_MIN_POS): New macro.
(display_line): Use it to record the minimum and maximum buffer
positions for glyphs in the row being assembled. If word wrap is
in effect, restore minimum and maximum positions seen up to the
wrap point, when iterator returns to it.
(find_row_edges): Fix logic; eol_pos should be tested before the
rest.
(try_window_reusing_current_matrix): Give up if in bidi-reordered
row and cursor not already at point. Restore original pre-bidi
code for unidirectional buffers.
bidi.c (bidi_cache_shrink, bidi_cache_iterator_state): Fix
reallocation of the cache. (Bug#6210)
(bidi_cache_iterator_state): Don't zero out new_paragraph (it is
not copied by bidi_copy_it).

xdisp.c (try_cursor_movement): Give up if rows are
bidi-reordered and point moved backwards. Examine all the
candidate rows that occlude point, to return the best match.
(row_containing_pos): With bidi-reordered rows, don't return the
first one that occludes point; rather, examine all candidates and
return the best match, with he glyph that's closest to point.
(display_line): When looking for min position, don't consider
negative values of glyph->charpos. (Fixes a crash with "C-x 3" at
ZV.) Record the position after EOL in it->eol_pos, and use it to
set end_pos of the last row produced for a continued line. Fix
the condition for passing candidate rows to set_cursor_from_row:
check ends_at_zv_p flag of the best candidate row, not of the
current row.
dispextern.h (struct it): New member eol_pos.
.gdbinit (prowlims): Display the ends_at_zv_p flag.

xdisp.c (display_line): Special-case the calculation of row->end
in rows that end at ZV, to avoid abort in CHAR_TO_BYTE. Handle
empty lines correctly when calculating row's max and min pos.
Display cursor at the first glyph row that has its ends_at_zv_p
flag set.

Region display and extension seems to work.
Solved a crash in bidirectional display of etc/HELLO.
(HELLO display still not 100% OK, e.g. near Kannada.)
.gdbinit (pitx): Display some bidi information about the
iterator.
dispextern.h (BIDI_AT_BASE_LEVEL): Enclose definition in
parentheses.
xdisp.c (handle_stop_backwards): Save and restore it->current
and it->position, instead of expecting the caller to do that.
(next_element_from_buffer): When moving across stop_charpos,
record it in prev_stop. When IT_CHARPOS backs up, call
handle_stop_backwards only if above the base embedding level.
This solves the crash while displaying etc/HELLO in bidi mode.

Redesign handle_stop_backwards.
Fix character mirroring for non-ASCII characters.
xdisp.c (handle_stop_backwards): Call compute_stop_pos in the
loop, instead of calling handle_stop. Call handle_stop only once,
after the loop.
(next_element_from_buffer): Don't call handle_stop_backwards if at
stop position. If base_level_stop is zero, set it to 1.
term.c (append_glyph): Fill resolved_level and bidi_type slots
of struct glyph for unidirectional display.
xdisp.c (set_cursor_from_row): Handle zero-width characters.
bidi.c (bidi_mirror_char): More efficient code (suggested by
Ehud Karni <[email protected]>). Don't even try to mirror
non-ASCII characters.
