* The linker command line option --print-map-locals can be used to include
local symbols in a linker map. (ELF targets only).
+* A new linker script sorting directive has been added: REVERSE. This reverses
+ the order of the sorting. It be combined with either SORT_BY_INIT_PRIORITY
+ or SORT_BY_NAME.

* For most ELF based targets, if the --enable-linker-version option is used
then the version of the linker will be inserted as a string into the .comment

@code{SORT} is an alias for @code{SORT_BY_NAME}.
+@cindex REVERSE
+@code{REVERSE} indicates that the sorting should be reversed. If used
+on its own then @code{REVERSE} implies @code{SORT_BY_NAME}, otherwise
+it reverses the enclosed @code{SORT..} command. Note - reverse
+sorting of alignment is not currently supported.
+
+Note - the sorting commands only accept a single wildcard pattern. So
+for example the following will not work:
+@smallexample
+ *(REVERSE(.text* .init*))
+@end smallexample
+To resolve this problem list the patterns individually, like this:
+@smallexample
+ *(REVERSE(.text*))
+ *(REVERSE(.init*))
+@end smallexample
+
+Note - you can put the @code{EXCLUDE_FILE} command inside a sorting
+command, but not the other way around. So for example:
+@smallexample
+ *(SORT_BY_NAME(EXCLUDE_FILE(foo) .text*))
+@end smallexample
+will work, but:
+@smallexample
+ *(EXCLUDE_FILE(foo) SORT_BY_NAME(.text*))
+@end smallexample
+will not.

When there are nested section sorting commands in linker script, there
can be at most 1 level of nesting for section sorting commands.
