(RE_SETUP_SYNTAX_TABLE_FOR_OBJECT): Simplify

2023-04-12T20:32:39+00:00

It turns out all calls to this function pass the same value
for the `count` argument, and they're all in `regexp.c`.

* src/syntax.c (RE_SETUP_SYNTAX_TABLE_FOR_OBJECT):
Rename from `SETUP_SYNTAX_TABLE_FOR_OBJECT`.  Remove `count` argument.
Move call to `RE_SYNTAX_TABLE_BYTE_TO_CHAR` to where its result is
actually used.
* src/regex-emacs.c (re_search_2, re_match_2): Adjust accordingly.

* src/syntax.h (RE_SYNTAX_TABLE_BYTE_TO_CHAR): Rename from
`SYNTAX_TABLE_BYTE_TO_CHAR` to clarify that it takes a byteoffset as
used in the regexp engine and not a "bytepos".  Adjust all callers.

src/regex-emacs.c (POS_AS_IN_BUFFER): Delete macro

2023-04-12T19:44:58+00:00

That macro added 1 to buffer positions because:

    Strings are 0-indexed, buffers are 1-indexed

but the reality is that this 1 was added to the regexp engine's "byte
offsets" which are not 1-based byte positions as used throughout
the rest of Emacs, but they are BEGV_BYTE-relative offsets, so the two
did not cancel out.

* src/regex-emacs.c (PTR_TO_OFFSET, POS_AS_IN_BUFFER): Delete macros;
use `POINTER_TO_OFFSET` instead.
(re_search_2, re_match_2, re_match_2_internal): Adjust accordingly.
* src/syntax.h (SYNTAX_TABLE_BYTE_TO_CHAR): Don't remove 1 from buffer
byteoffsets now that `POS_AS_IN_BUFFER` doesn't add it any more.

(struct gl_state_s): Delete `offset` field

2023-04-12T19:20:07+00:00

`gl_state` had an `offset` field because:

    For buffers, regex-emacs.c passes arguments to the
    UPDATE_SYNTAX_TABLE functions which are relative to BEGV

but the reality is that these arguments are byte offsets relative to
BEGV_BYTE whereas `offset` was counted in chars, so the two didn't
cancel each other out.

* src/syntax.h (struct gl_state_s): Delete `offset` field.
(UPDATE_SYNTAX_TABLE_FORWARD, UPDATE_SYNTAX_TABLE_BACKWARD)
(SYNTAX_TABLE_BYTE_TO_CHAR):
* src/syntax.c (SETUP_SYNTAX_TABLE, SETUP_SYNTAX_TABLE_FOR_OBJECT)
(update_syntax_table, skip_syntaxes): Simplify accordingly.

Remove unused fns/data and make fns static

2022-03-19T19:48:53+00:00

* src/comp.c (saved_sigset, helper_temp_output_buffer_setup):
Remove; unused.
* src/comp.c (logfile, helper_link_table):
* src/fns.c (hashfn_equal, hashfn_eql):
* src/frame.c (frame_windows_min_size):
* src/gnutls.c (emacs_gnutls_global_init):
* src/minibuf.c (Vcommand_loop_level_list):
* src/syntax.c (syntax_code_spec):
* src/timefns.c (time_overflow):
* src/xterm.c (x_xrender_color_from_gc_foreground)
(x_display_set_last_user_time):
Now static, since it’s not used elsewhere.
* src/xterm.c (x_xrender_color_from_gc_foreground)
(x_xrender_color_from_gc_background): Move earlier to avoid
forward use.
(x_xrender_color_from_gc_foreground): Do not define unless
!defined USE_CAIRO && (RENDER_MAJOR > 0 || RENDER_MINOR >= 2),
since it’s not used otherwise.
