+ * NEWS: Mention new option.
+ * lexsup.c (parse_args): Handle --print-memory-usage.
+ (ld_options): Add --print-memory-usage.
+ * ldmain.c (main): Call lang_print_memory_usage.
+ * ldlex.h (enum option_values): Add OPTION_PRINT_MEMORY_USAGE.
+ * ldlang.h: Add prototype of lang_print_memory_usage.
+ * ldlang.c (lang_print_memory_size, lang_print_memory_usage): New
+ functions.
+ * ld.texinfo (Options): Document --print-memory-usage.
+ * ld.h (args_type): Add print_memory_usage field.

* po/fr.po: Updated French Translation.
* Add support for LLVM plugin.
+* Add --print-memory-usage option to report memory blocks usage.

Changes in 2.25:
* PE binaries now once again contain real timestamps by default. To disable
/* If TRUE we'll just print the default output on stdout. */

in an @code{OUTPUT_FORMAT} linker script command (@pxref{File Commands}).
+@kindex --print-memory-usage
+@cindex memory usage
+@item --print-memory-usage
+Print used size, total size and used size of memory regions created with
+the @ref{MEMORY} command. This is useful on embedded targets to have a
+quick view of amount of free memory. The format of the output has one
+headline and one line per region. It is both human readable and easily
+parsable by tools. Here is an example of an output:
+
+@smallexample
+Memory region Used Size Region Size %age Used
+ ROM: 256 KB 1 MB 25.00%
+ RAM: 32 B 2 GB 0.00%
