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

/* Hey Emacs, this is -*- C -*- code! */

/* Synched up with: Not synched with FSF. */

/* Think twice before editing this file.  Generated automatically by configure.

 The file startup.el guesses at reasonable values for load-path, exec-path,
 and lock-directory.  This means that if you move emacs and its associated
 sub-tree to a different place in the filesystem, or to a different machine,
 you won't have to do anything for it to work.

 If you define the paths in this file then they will take precedence over
 any value generated by the heuristic in startup.el.  The hardcoded paths
 will be checked to see if they are valid, in which case they will be used.
 Otherwise the editor will attempt to make its normal guess.

 See the NEWS file for a description of the heuristic used to locate the lisp
 and exec directories at startup time.  If you are looking at this file
 because you are having trouble, then you would be much better off arranging
 for those heuristics to succeed than defining the paths in this file.

   **  Let me say that again.  If you're editing this file, you're making
   **  a mistake.  Re-read the section on installation in ../etc/NEWS.

 If it defines anything, this file should define some subset of the following:

   PATH_PREFIX		The default value of `prefix-directory'.  This is the
   			default root for everything.

   PATH_LOADSEARCH	The default value of `load-path'.

   PATH_EXEC		The default value of `exec-directory' and `exec-path'.
			(exec-path also contains the value of whatever is in
			the PATH environment variable.)

   PATH_DATA		The default value of `data-directory'.  This
			is where architecture-independent files are
			searched for.

   PATH_LOCK		The name of the directory that contains lock files
			with which we record what files are being modified in 
			Emacs.  This directory should be writable by everyone.
			If this is specified, the string must end with a slash!

   PATH_SUPERLOCK	The name of the file !!!SuperLock!!! in the lock 
			directory.  You probably should let this default...

   PATH_INFO		The default value of `Info-directory-list'.
			This is where info files are searched for. */
