--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- https://gcc.gnu.org/onlinedocs/gcc-7.3.0/gcc/Optimize-Options.html#index-fdelete-null-pointer-checks This option is enabled by default on most targets. On Nios II ELF, it defaults to off. On AVR and CR16, this option is completely disabled. --- CUT --- Does that explain the difference with respect of -fdelete-null-pointer-checks ?
