9.11.14 Unique_section Variable Attribute

The unique_section attribute places the variable in a uniquely named section, just as if -fdata-sections had been specified. If the variable also has a section attribute, use that section name as the prefix for generating the unique section name.

For example,
int tin __attribute__ ((section (".ofcatfood"), unique_section)
will place the variable tin in section .ofcatfood.
