annotate lisp/lisp-mode.el @ 4910:6bc1f3f6cf0d
Make canoncase visible to Lisp; use it with chars in internal_equalp.
src/ChangeLog addition:
2010-02-01 Aidan Kehoe <kehoea@parhasard.net>
* fns.c (internal_equalp):
Use bytecode_arithcompare, which takes two args, instead of
passing a stack pointer to Feqlsign.
Use CANONCASE(), not DOWNCASE(), for case-insensitive character
comparison.
Correct a comment here.
* casefiddle.c (casify_object): New operation in this function,
CASE_CANONICALIZE.
(Fcanoncase): New function, used for case-insensitive comparison.
* lisp.h:
Make Fcanoncase, bytecode_arithcompare visible here.
* bytecode.c (bytecode_arithcompare):
Make this visible to other files.
lisp/ChangeLog addition:
2010-02-01 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (equalp):
Remove special treatment for an #'equalp with a single character
constant argument, it was incorrect (it used #'downcase instead of
#'canoncase).
