- Why is -march=native not enabled by default by compilers IDEs?
For -O0, whether -march=native or -march=<generic> is the default still specifies the same family, so both are perfectly compatibly with -O0; and whenever another optimization level is specified, -march=native is beneficial to performance So, for me, the fact that -O0 is the default doesn't matter for -march's default –
- What are my available march mtune options? - Stack Overflow
-march=native will pick the right arch and tune settings for the machine the compiler is running on, or tune=generic if the compiler doesn't recognize the specific model of CPU it's running on (e g old gcc on a Skylake, will still enable -mavx2 -mpopcnt -mbmi2 and so on, but will set -mtune=generic instead of something closer to appropriate )
- Implementation of March memory testing algorithm
If you need to perform a fast BIST for example, you can fill memory with prand numbers read back, fill with the inverse of the same prand numbers, read back Or performing a prand test first to weed out the blatantly bad boards, then perform the March tests with perhaps the exception of the address test

- GCC: mtune vs march vs mcpu - Stack Overflow
However, I've read that -mcpu is possibly the best flag to set instead of -march or -mtune as -mcpu is specific to the very processor, not just the more common architecture specified by -marm (a difference of something like -mcpu=cortex-a8 over -march=armv7-a)
- gcc generic march for all the x64 platforms - Stack Overflow
GCC have -march= and -mtune option as described here But it is not obvious which of the options to choose for x64 platform as generic one Say, -mtune= have the generic value, but -march= for x64 have no I suspect that -march=nocona (as frequently seen everywhere) or even -march=i686 -m64 is the solution, but I'm not sure
