+       default n
+       help
+         Enable this function to disable link-time optimizations.
+         The default linker behavior is to combine identical literal
+         values to reduce code size and remove unnecessary overhead from
+         assembler-generated 'longcall' sequences.
+         Enabling this option improves the link time but increases the
+         code size, and possibly execution time.
