Code size optimization for stm8 microcontroller using STM8-DCE

how can I add STM8-DCE for compiling a project for the stm8 microcontroller so that it removes unused functions for size optimization when compiling via SDCC, here is the project address GitHub - CTXz/STM8-DCE: SDCC STM8 Dead Code Elimination Tool

See https://github.com/maxgerhardt/pio-stm8-dce.
