* src/fileio.c (Fexpand_file_name): Don't build multibyte strings
from unibyte non-ASCII strings when NAME and DEFAULT_DIRECTORY
have different multibyteness, as this adds bytes to the byte
sequence, and in some situations, e.g., when the home directory
includes non-ASCII characters, can fail file APIs. (Bug#30755)
* lisp/startup.el (normal-top-level): Make sure default-directory
is set to a multibyte string when decoded on MS-Windows.
(cherry picked from commit 3aab8626ba)
* src/font.c (font_open_entity): Fail after 15 iterations through
the loop that looks for a font whose average_width and height are
both positive. This avoids infinite loops for fonts that, e.g.,
report average_width of zero for any possible size we try.
(Bug#31316)
(cherry picked from commit e2879c1f83)
* src/xdisp.c (move_it_in_display_line_to): Avoid looping in
previous/next-line when wrap-prefix is set to a too-wide
stretch of whitespace. (Bug#30432)
(cherry picked from commit 842b3d7412)
* src/xdisp.c (display_line): Avoid looping in redisplay when
wrap-prefix is set to a too-wide stretch of whitespace.
(Bug#30432)
(cherry picked from commit 2a1fe08307)
* src/xdisp.c (pos_visible_p): For the leftmost glyph, adjust the X
coordinate due to line-number display. (Bug#30834)
(cherry picked from commit 4a20174d79)
* src/xdisp.c (Fwindow_text_pixel_size): Adjust the return value
when we stop one buffer position short of TO. (Bug#30746)
(cherry picked from commit 33cba5405c)
* src/xdisp.c (move_it_to): Initialize the line_number_produced_p
flag before iterating on a new line. (Bug#30818)
(cherry picked from commit 5c585b8b99)
* src/xdisp.c (Fwindow_text_pixel_size): Correct the result when
there's a display property at the TO position, and the call to
move_it_to overshoots. (Bug#30746)
(cherry picked from commit 50e2c0fb51)
* src/dispextern.h (struct it): New members tab_offset and
line_number_produced_p.
* src/xdisp.c (display_line): Don't set row->x to a negative value
if line numbers are being displayed. (Bug#30582)
Reset the line_number_produced_p flag before laying out the glyph
row.
(x_produce_glyphs): Use the line_number_produced_p flag to decide
whether to offset the X coordinate due to line-number display.
Use the tab_offset member to restore the original TAB width for
alignment purposes.
(move_it_in_display_line_to): Don't produce line numbers when moving
in hscrolled window to the left of first_visible_x.
(maybe_produce_line_number): Set the line_number_produced_p flag.
(Bug#30584)
* src/term.c (produce_glyphs): Correct TAB width only when
line_number_produced_p flag is set.
(cherry picked from commit 1ac1905538)
* src/process.c (read_process_output): Track bytes read from
a process.
(wait_reading_process_output): If called recursively through
timers and/or process filters via accept-process-output, it is
possible that the output of wait_proc has already been read by
one of those recursive calls, leaving the original call hanging
forever if no further output arrives through that fd and no
timeout has been set. Fix that by using the process read
accounting to keep track of how many bytes have been read and
use that as a condition to break out of the infinite loop and
return to the caller as well as to calculate the proper return
value (if a wait_proc is given that is).
* src/process.h (struct Lisp_Process): Add nbytes_read to track
bytes read from a process.
(cherry picked from commit 4ba32858d6)
* src/dispnew.c (buffer_posn_from_coords): Improve commentary.
* src/xdisp.c (move_it_in_display_line_to): Don't exit the loop
under truncate-lines if the glyph at TO_CHARPOS was not yet
produced. This avoids bailing out too early when we are at
TO_CHARPOS, but didn't yet produce glyphs for that buffer
position, because the last call to PRODUCE_GLYPHS at this position
was for an object other than the buffer. For further details, see
http://lists.gnu.org/archive/html/emacs-devel/2018-01/msg00537.html.

The check-syntax target is enabled the use of Flymake's "legacy"
backend, flymake-proc-legacy-flymake in src/*.c. It works quite well

In GCC 8, gcc -fsanitize=undefined flags the undefined behavior
that Emacs relies on in its XPNTR and XSYMBOL low-level functions.
Disable undefined sanitization in these functions. Although this
disabling doesn’t suffice if DEFINE_KEY_OPS_AS_MACROS is true, it
works for -fsanitize=undefined -DINLINING=0, which is good enough.

(PNTR_ADD): New function and macro.
The function disables -fsanitize=undefined.
(macro_XPNTR): Use it.
* src/conf_post.h (ATTRIBUTE_NO_SANITIZE_UNDEFINED): New macro.
* src/lisp.h (XSYMBOL): Disable -fsanitize=undefined.
* src/fileio.c (Fexpand_file_name): Don't build multibyte strings

sequence, and in some situations, e.g., when the home directory
includes non-ASCII characters, can fail file APIs. (Bug#30755)
