When building with both -ffunction-sections and
-g, the compiler outputs an invalid warning for
each compiled file:
drv/timer.c:1: warning: -ffunction-sections may affect debugging on some
targets
The code printing this is here:
--- gcc/toplev.c ---
#ifndef OBJECT_FORMAT_ELF
if (flag_function_sections && write_symbols != NO_DEBUG)
warning ("-ffunction-sections may affect debugging on some targets");
#endif
--- gcc/toplev.c ---
A possible fix could be adding elfos.h to the tm_file
list for the avr target in config.gcc, which may also
lead to simplifications in some parts of config/avr.h.
