You're thinking of -march=native. It's not set by default, but you might find it set in a makefile.Why do you think you need to use any -march option?Well, for all I knew, absence of any option could mean that gcc generates code for the machine where I run the compile command, and not for others. Following that logic, I expected to need a -march option.
