Use the existing C-level line number cache within #'line-number.
src/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* buffer.c:
* buffer.c (Fline_number): New C implementation, using the line
number cache of line-number.c, with a new optional BUFFER
argument.
* buffer.c (syms_of_buffer):
Make it available to Lisp.
* line-number.c (buffer_line_number):
New argument, RESPECT-NARROWING, describing whether to count from
the beginning of the visible region or from the beginning of the
buffer.
* line-number.h:
* line-number.h (buffer_line_number): Update its declaration.
* redisplay.c (window_line_number): Call it with the new argument.
lisp/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* simple.el:
* simple.el (line-number): Moved to buffer.c; we have an existing
line number cache in C, it's a shame not to have it available.

line source
This directory contains C header files containing machine-specific definitions. Each file describes a particular machine. The emacs configuration script edits ../config.h to include the appropriate one of these files, and then each emacs source file includes config.h. template.h is a generic template for machine descriptions; it describes the parameters a machine file can specify. General XEmacs Changes ---------------------- 1. Removed all code dealing with VALBITS and XSET*. These are handled differently in XEmacs. 2. Removed all defines of WORDS_BIGENDIAN. Now determined by configure. 3. Put #ifndef PURESIZE around all PURESIZE defines so that it can be overridden at configure time. 4. Removed all defines of NO_ARG_ARRAY. The arg-array hack is not done in XEmacs. (If you want to put it back, use configure -- autoconf has a check for this.) 5. Removed all defines of BITS_PER_INT, BITS_PER_LONG -- now determined by configure. See ../s/README for a list of other changes made to the FSF 19.30 configuration files for XEmacs.
