Add compiler macros and compilation sanity-checks for functions with keywords. 2010-10-25 Aidan Kehoe <kehoea@parhasard.net> Add compiler macros and compilation sanity-checking for various functions that take keywords. * byte-optimize.el (side-effect-free-fns): #'symbol-value is side-effect free and not error free. * bytecomp.el (byte-compile-normal-call): Check keyword argument lists for sanity; store information about the positions where keyword arguments start using the new byte-compile-keyword-start property. * cl-macs.el (cl-const-expr-val): Take a new optional argument, cl-not-constant, defaulting to nil, in this function; return it if the expression is not constant. (cl-non-fixnum-number-p): Make this into a separate function, we want to pass it to #'every. (eql): Use it. (define-star-compiler-macros): Use the same code to generate the member*, assoc* and rassoc* compiler macros; special-case some code in #'add-to-list in subr.el. (remove, remq): Add compiler macros for these two functions, in preparation for #'remove being in C. (define-foo-if-compiler-macros): Transform (remove-if-not ...) calls to (remove ... :if-not) at compile time, which will be a real win once the latter is in C. (define-substitute-if-compiler-macros) (define-subst-if-compiler-macros): Similarly for these functions. (delete-duplicates): Change this compiler macro to use #'plists-equal; if we don't have information about the type of SEQUENCE at compile time, don't bother attempting to inline the call, the function will be in C soon enough. (equalp): Remove an old commented-out compiler macro for this, if we want to see it it's in version control. (subst-char-in-string): Transform this to a call to nsubstitute or nsubstitute, if that is appropriate. * cl.el (ldiff): Don't call setf here, this makes for a load-time dependency problem in cl-macs.el

This directory contains a number of XEmacs dynamic modules.  These
modules can be loaded directly with the command 'M-x load-module'.
However, the preferred method of loading a module is to issue a
"(require 'module-name)" command to the Lisp interpreter.  This will
store information so that a later "(unload-feature 'module-name)" can
succeed.

To compile one of these modules, simply enter the desired directory,
type 'configure', and then 'make'.  If you are building the module for
an installed XEmacs, then 'make install' will place the module in the
appropriate directory for XEmacs to find it later (assuming you have
permission to write to that directory).  A subsequent 'load-module' or
'require' will then load the module, as described above.

Each of these demonstrates different features and limitations of the
XEmacs module loading technology.  For a complete discussion on XEmacs
dynamic modules, please consult the XEmacs Module Writers Guide, which
can be found in the ../info directory.

For those wanting to get started with module writing, please see the
'sample' directory.  It contains two subdirectories: internal and
external.  The 'internal' subdirectory contains the framework needed to
migrate some core piece of XEmacs functionality into code that can
either be compiled into the core or built as a separate module.  The
'external' subdirectory contains the somewhat simpler framework needed
to build a module separately from XEmacs.  These should be considered
starting places for module writing.
