Hi This is to do with binutils but I believe it's OK to discuss it here since it's more AVR ABI related.
At present, we use first 7 bits (bits 0-6) of e_flags of the ELF header for specifying the "arch" (ISA variation) and the 8th bit (bit 7) is used for EF_AVR_LINKRELAX_PREPARED to indicate that the object file uses local symbols as reference. The remaining bits are unused. I am trying to introduce a new series for Tiny core. As I see 0xx series is used for Mega and 1xx series is used for XMega now. If I have to have 200 series for Tiny, I need to move the EF_AVR_LINKRELAX_PREPARED to a different position. I know this will cause binary incompatibility with older versions, But I propose that we move this to 31st bit (e_flags is of type ELF32_Word). Comments?
