Unrool a load-time loop at macro expansion time, cl-macs.el
2010-12-29 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (inline-side-effect-free-compiler-macros):
Unroll a loop here at macro-expansion time, so these compiler
macros are compiled. Use #'eql instead of #'eq in a couple of
places for better style.

| 6260 Use this to conditionalize execution of lisp code based on the | |
| 6261 presence or absence of emacs or environment extensions. | |
| 6262 FEXP can be a symbol, a number, or a list. | |
| 6263 If it is a symbol, that symbol is looked up in the `features' variable, | |
| 6264 and non-nil will be returned if found. | |
| 6265 If it is a number, the function will return non-nil if this Emacs | |
| 6266 has an equal or greater version number than FEXP. | |
| 6267 If it is a list whose car is the symbol `and', it will return | |
| 6268 non-nil if all the features in its cdr are non-nil. | |
| 6269 If it is a list whose car is the symbol `or', it will return non-nil | |
| 6270 if any of the features in its cdr are non-nil. | |
| 6271 If it is a list whose car is the symbol `not', it will return | |
| 6272 non-nil if the feature is not present. | |
| 6273 | |
| 6274 Examples: | |
| 6275 | |
| 6276 (featurep 'xemacs) | |
| 6277 => ; Non-nil on XEmacs. | |
| 6278 | |
| 6279 (featurep '(and xemacs gnus)) | |
| 6280 => ; Non-nil on XEmacs with Gnus loaded. | |
| 6281 | |
| 6282 (featurep '(or tty-frames (and emacs 19.30))) | |
| 6283 => ; Non-nil if this Emacs supports TTY frames. | |
| 6284 | |
| 6285 (featurep '(or (and xemacs 19.15) (and emacs 19.34))) | |
| 6286 => ; Non-nil on XEmacs 19.15 and later, or FSF Emacs 19.34 and later. | |
