+
+ Fix integer width and related bugs (Bug#9874).
+ * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
+ (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
+ (string_bytes, check_sblock, allocate_string_data):
+ (compact_small_strings, Fmake_bool_vector, make_string)
+ (make_unibyte_string, make_multibyte_string)
+ (make_string_from_bytes, make_specified_string)
+ (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
+ (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
+ (mark_vectorlike):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ (allocate_pseudovector):
+ Use int, not EMACS_INT, where int is wide enough.
+ (inhibit_garbage_collection, Fgarbage_collect):
+ Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
+ * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
+ int might not be wide enough.
+ (bidi_cache_search, bidi_cache_find, bidi_init_it)
+ (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
+ (bidi_at_paragraph_end, bidi_find_paragraph_start)
+ (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
+ (bidi_level_of_next_char, bidi_move_to_visually_next):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
+ (Fkill_buffer, Fset_buffer_major_mode)
+ (advance_to_char_boundary, Fbuffer_swap_text)
+ (Fset_buffer_multibyte, overlays_at, overlays_in)
+ (overlay_touches_p, struct sortvec, record_overlay_string)
+ (overlay_strings, recenter_overlay_lists)
+ (adjust_overlays_for_insert, adjust_overlays_for_delete)
+ (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
+ (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
+ (Foverlay_recenter, last_overlay_modification_hooks_used)
+ (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ (validate_region): Omit unnecessary test for b <= e,
+ since that's guaranteed by the previous test.
+ (adjust_overlays_for_delete): Avoid pos + length overflow.
+ (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
+ (report_overlay_modification):
+ Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
+ (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
+ Omit pointer cast, which isn't needed anyway, and doesn't work
+ after the EMACS_INT -> ptrdiff_t change.
+ (Fmove_overlay): Delete an evaporating overlay
+ if it becomes empty after its bounds are adjusted to fit within
+ its buffer. Without this fix, in a nonempty buffer (let ((o
+ (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
+ yields an empty overlay that has the evaporate property, which is
+ not supposed to happen. (Bug#9642)
+ * buffer.h: Adjust decls to match defn changes elsewhere.
+ (struct buffer_text, struct buffer):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ Use EMACS_INT, not int, where int might not be wide enough.
+ * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
+ not int, to avoid needless 32-bit limit on 64-bit hosts.
+ (exec_byte_code): Use tighter memory-full test, one that checks
+ for alloca overflow. Don't compute the address of the object just
+ before an array, as that's not portable. Use EMACS_INT, not
+ ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
+ * callint.c (Fcall_interactively):
+ Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
+ * callproc.c (call_process_kill, Fcall_process):
+ Don't assume pid_t fits into an Emacs fixnum.
+ (call_process_cleanup, Fcall_process, child_setup):
+ Don't assume pid_t fits into int.
+ (call_process_cleanup, Fcall_process, delete_temp_file)
+ (Fcall_process_region):
+ Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

+ (Fupcase_word, Fdowncase_word, Fcapitalize_word):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ (casify_object): Avoid integer overflow when overallocating buffer.
+ * casetab.c (set_identity, shuffle): Prefer int to unsigned when
+ either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
+ * category.c (Fchar_category_set): Don't assume fixnum fits in int.
+ * category.h (CATEGORYP): Don't assume arg is nonnegative.
+ * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
+ integers are now checked earlier. All uses replaced with XINT.
+ (ccl_driver):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ For CCL_MapSingle, check that content and value are in int range.
+ (ccl_driver, Fregister_code_conversion_map):
+ Check that Vcode_version_map_vector is a vector.
+ (resolve_symbol_ccl_program): Check that vector header is in range.
+ Always copy the vector, so that we can check its contents reliably
+ now rather than having to recheck each instruction as it's being
+ executed. Check that vector words fit in 'int'.
+ (ccl_get_compiled_code, Fregister_ccl_program)
+ (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
+ program indexes, to avoid needless 32-bit limit on 64-bit hosts.
+ (Fccl_execute, Fccl_execute_on_string): Check that initial reg
+ contents are in range.
+ (Fccl_execute_on_string): Check that status is in range.
+ * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
+ * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
+ Accept and return EMACS_INT, not int, because callers can pass values
+ out of 'int' range.
+ (c_string_width, strwidth, lisp_string_width, chars_in_text)
+ (multibyte_chars_in_text, parse_str_as_multibyte)
+ (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
+ (str_as_unibyte, str_to_unibyte, string_count_byte8)
+ (string_escape_byte8, Fget_byte):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
+ avoid mishandling large integers.
+ * character.h: Adjust decls to match defn changes elsewhere.
+ * charset.c (load_charset_map_from_file, find_charsets_in_text)
+ (Ffind_charset_region):
+ Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
+ (load_charset_map_from_file): Redo idx calculation to avoid overflow.
+ (load_charset_map_from_vector, Fdefine_charset_internal):
+ Don't assume fixnum fits in int.
+ (load_charset_map_from_vector, Fmap_charset_chars):
+ Remove now-unnecessary CHECK_NATNUMs.
+ (Fdefine_charset_internal): Check ranges here, more carefully.
+ Don't rely on undefined behavior with signed left shift overflow.
+ Don't assume unsigned int fits into fixnum, or that fixnum fits
+ into unsigned int. Don't require max_code to be a valid fixnum;
+ that's not true for gb10830 4-byte on a 32-bit host. Allow
+ invalid_code to be a cons, for the same reason. Require code_offset
+ to be a character. Avoid int overflow if max_char is close
+ to INT_MAX.
+ (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
+ this is intended anyway and avoids some undefined behavior.
+ (load_charset_map): Pass unsigned, not int, as 2nd arg of
+ INDEX_TO_CODE_POINT, as that's what it expects.
+ (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
+ * charset.h (DECODE_CHAR): Return int, not unsigned;
+ this is what was intended anyway, and it avoids undefined behavior.
+ (CHARSET_OFFSET): Remove unused macro, instead of fixing its
+ integer-overflow issues.
+ (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
+ Formerly, it returned EMACS_INT on 64-bit hosts in the common case
+ where the argument is EMACS_INT, and this behavior is not intended.
+ * chartab.c (Fmake_char_table, Fset_char_table_range)
+ (uniprop_get_decoder, uniprop_get_encoder):
+ Don't assume fixnum fits in int.
+ * cmds.c (move_point): New function, that does the gist of
+ Fforward_char and Fbackward_char, but does so while checking
+ for integer overflow more accurately.
+ (Fforward_char, Fbackward_char): Use it.
+ (Fforward_line, Fend_of_line, internal_self_insert)
+ (internal_self_insert):
+ Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+ Fix a FIXME, by checking for integer overflow when calculating
+ target_clm and actual_clm.
+ * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
+ (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
