I mean, > when none of them are used. By default the fixes will not be applied i.e. the behaviour will be equivalent to -mno-fix-cortex-a53-835769 and -mno-fix-cortex-a53-843419. However, you (or your compiler vendor) can configure GCC during GCC compile time with the --enable-fix-cortex-a53-843419 or --enable-fix-cortex-a53-835769 options. In that case the fixes will be applied automatically i.e. behave as if -mfix-cortex-a53-843419 or -mfix-cortex-a53-835769 were specified. You can find out if your GCC distribution enables these configuration options automatically by running gcc with the "-v" option, and seeing if any of those two --enable-fix* options appear in the configuration options.
