Re: [PATCH] Do not emit __gnu_lto_v1 symbol.

[Georg-Johann Lay]

Hi Martin.

In SVN r273662 you changed a comment in avr.c from __gnu_lto_v1 to 
__gnu_lto_slim without changing the relevant code:

  /* __gnu_lto_slim is just a marker for the linker injected by toplev.c.
     There is no need to trigger __do_clear_bss code for them.  */

  if (!STR_PREFIX_P (name, "__gnu_lto"))
    avr_need_clear_bss_p = true;

This means that just defining symbol __gnu_lto_slim will trigger code 
from libgcc (code to clear .bss, which is supposed to be conditional 
depending on whether .bss actually contains anything).

Would you also adjust that test?

Thanks,

Johann
